Arian Edalat spent the first half of his 22 years in desalination watching membranes foul, and the second half learning to talk back to them: Active Membranes, co-founded on a UCLA coating, makes a reverse-osmosis membrane electrically conductive, feeds it a few volts and lets the surface repel the salts that would crust onto it. In its first long pilot, in Yuma, Arizona, that meant run at 84% recovery with no antiscalant, about 92% with a second stage on the brine, and cleaning events cut from nine to three, by the company’s count. But the money is what caught my attention: Arian has raised about $3.2 million, grants included, and the $5 million round he is raising now is meant to be the last one before profitability. So, with ZwitterCo at close to $98 million for a membrane, I went into my Leviathan database to see whether the market agrees.

Why do reverse osmosis membranes foul, and what does it cost?

Every desalination plant is engineered around one enemy. Fouling, the organic layers that settle on a membrane, and scaling, minerals such as gypsum crystallising on its surface, cost an operator chemicals, energy, downtime and membranes: nine cleaning events in nine months on the Yuma plant Arian Edalat piloted on. And he calls it the tail that wags the dog.

Reverse osmosis, RO from here on, pushes salty water through a membrane at pressure so that only the water gets across, and the membrane has no say in what arrives (in Arian’s words it is a dumb plastic), so everything upstream of it exists to protect it. I made the same point in my desalination editorial last year: RO uses about ten times less energy than boiling seawater, but its membranes foul, scale and break like any industrial process. Well, the bill lands on the operator, because an hour of cleaning in 50°C heat is an hour a community goes without water. NALA Membranes attacks the same pain from the material side, with a polymer that survives chlorine.

How does an electrically conductive membrane stop scaling?

Active Membranes coats a standard polyamide RO membrane until its surface resistivity (the resistance across one square of surface, in ohms per square) drops from 10^7 to between 100 and 200, about five orders of magnitude. A low-voltage alternating signal, 4 volts at 1 hertz, then lets the charged surface repel charged ions before they nucleate, or seed a first crystal.

Now, polyamide is the thin active layer of nearly every RO membrane sold today, and it is an insulator, so nobody had bothered to plug one in. So I will spare you the physics (I did some a long time ago, and it did not end well), because Arian’s own summary lands it better: the coated sheet ends up, in his words, “infinitely more conducting to electrical current”. And once electrons move through the surface, the membrane can push away the calcium, sulfate and other charged species that would seed a crystal, and because you can read its performance as you vary voltage, waveform and frequency, it tells you when a water is beating it.

Inside the Yuma pilot: 75% to 92% recovery, nine cleanings to three

In Yuma, Arizona, a brackish-water plant ran at 75% recovery. Without chemistry, the active membranes ran the same water at 84%; with a second stage on the brine, Arian puts the whole plant at about 92%, his figure, not a multiplication. Cleaning events fell from nine to three in nine months, and lifecycle savings came out between 32% and 60%.

Recovery rate is the share of the feed water that leaves a desalination plant as fresh water, the rest leaving as brine, so a plant at 75% sends a quarter of what it pumped in back out as brine, and every point of recovery is money twice. (Yes, I checked the company report in my Leviathan database before repeating this.) And it places Active Membranes at TRL 6 to 7, TRL being the NASA scale from 1 to 9 for how baked a technology is, so a prototype proven in real conditions, with 20-gallon-per-minute field trials on produced water and brackish groundwater. So, pilot figures, as the company reports them, and not yet a commercial plant.

Can you run reverse osmosis without antiscalant?

The single “aha” in head-to-head pilots is the missing chemical: no antiscalant dosing, no chemical clarifier upstream, one or two dosing pumps fewer, on the same skid, vessels and pump. And a produced-water site Arian had treated with two-stage chemical clarification in 2018 ran again with none, at half the footprint and half the cost.

An antiscalant is a chemical dosed continuously upstream of an RO membrane to keep dissolved minerals from crystallising on it; it buys higher recovery, at the price of a chemical bill that never stops and a brine that is harder to dispose of. Now, my objection on air was about who books the saving, because the business model of an engineering consultant is copy-paste (he recovers the margin lost on his first three plants by reproducing the design), and Arian’s answer is that the consultant can keep copy-pasting the RO skid and simply stop copying the clarifier and two of the dosing pumps. Look, I dissected that adoption-chain problem in my newsletter last November, and it does not go away because the physics is good.

Can a $200 paint sprayer become a membrane factory?

The first conductive sheets came off a Home Depot drum coated with a handheld wall sprayer, a $200 rig built to enter the US Bureau of Reclamation’s “More Water, Less Concentrate” prize. Its successor, the Spitfire, sprays and heats the coating, was chosen after 20 spraying methods were screened, and now coats sheets for standard 4-inch and 8-inch elements.

The method came out of David Jassby’s laboratory at UCLA, and in January 2024 the university’s newsroom listed Jassby and Eric Hoek among the company’s co-founders. Getting from a lab bench to a spiral-wound element, the rolled membrane cartridge that slides into a pressure vessel, usually eats a membrane start-up’s first tens of millions, because the industry’s answer is a big, chunky coating line. Well, Arian says he did not have that money, so he had to be creative, and the Spitfire is what creative looked like (the name is affectionate, the machine less so). And by November 2025, Aquatech reported the first standard 8040 modules, eight inches by forty, and a seawater pilot lined up in Israel.

Franchising membrane production: KFC for membranes

Now, two things keep RO membranes in a handful of hands, the five or so producers I counted out with Arian on air, arguably three big ones: the capital a coating line costs and its concentration in a few mega-sites. So Active Membranes’ answer is a “mother” facility in California and partner-run coating and rolling lines in their own markets.

So the pitch to a partner in Malta or the Gulf is that the Spitfire comes to you, you coat and roll locally, and you own a product your competitors cannot buy. Now, an OEM, the company that builds the RO skid, then gets to choose between selling one plant a year at $1 million or ten plants at $500,000, because a plant without a chemical clarifier and with fewer dosing pumps fits budgets and sites that never penciled out. And that is the opposite of the path ZwitterCo took, which I raised on air: raise tens of millions, build the plant, own the capacity. Both can be right, but the second is the one investors are trained to fund.

Seedstrapping: grants first, one seed, then stretch

Seedstrapping is the pattern I named the week this episode aired: bootstrap on grants and non-dilutive money to the first paying customers, take one modest seed, then stretch it toward profitability. Active Membranes has done the first two steps, about $3.2 million in total, and the $5 million round it is raising now is meant to be the stretch.

Non-dilutive funding is money a company receives without giving up shares: grants, government research contracts such as the US Small Business Innovation Research awards, or profits from a sister business, and Arian used all of them, the sister business being Pacifica Water Solutions, the consultancy he co-founded in 2019, which reinvested into the venture. And he is not alone on this microphone: Swapnil Shrivastav of Uravu Labs told me too much cash makes you solve problems by throwing money, and Fajer Mushtaq of Oxyle took a technology from lab to full-scale product on $3 million of equity and $6 million of non-dilutive money. But the other side of the ledger is SOURCE Global, whose collapse I took apart in June.

Why do water VCs want founders to raise less?

Peter Yolles, founder and managing partner of Echo River Capital, which my Leviathan database has in 23 water rounds across 18 companies, says he looks for a long runway of technology development before founders raise dilutive capital. When has a VC ever told anyone to take less of their money? Well, in water, they practically beg you to.

I spent two weeks of evenings on the newsletter that named seedstrapping, because I am fun at parties, and the numbers held: Correlation Ventures’ analysis of 21,000-plus deals, which I walked through in August 2025, has 65% of venture investments failing to return their capital and 4% returning ten times. And water is harsher still, because you need paying customers before the risky VCs return your call, so the founder who arrives with proof instead of projections has already done the investor’s de-risking for free (and yes, Peter backed both Active Membranes and Uravu Labs). So his line, below, should be taught in water entrepreneurship schools, if those existed.

Are water-tech checks really getting smaller?

In August 2025 I counted about $600 million into water tech, more checks than 2024 and about 10% smaller. The full year in my Leviathan database deepened it: with the largest round of each year removed, 178 rounds for $977 million in 2025 against 166 for $1.14 billion in 2024, so 7% more rounds and a 20% smaller average check.

I keep every water funding round I can document in Leviathan, and the largest round of each year distorts everything: Lilac Solutions’ $145 million in 2024, Tidal Vision’s $140 million in 2025. So take those two out, as I did on the podcast, and the average check falls from $6.9 million to $5.5 million.

But the average is not the number that matters to a founder. The median, the check right in the middle of the pile, went from $3.2 million in 2024 to $2.2 million in 2025, a third smaller, so more companies got funded and the typical one got less, which is the market voting for something like what Arian is doing.

How does $3.2 million compare with what membrane peers raised?

Active Membranes’ $2.33 million seed is a normal seed: the median seed round in my database was $2.2 million in 2024 and $2.0 million in 2025. But ZwitterCo raised $97.7 million across four rounds, NALA Membranes $19.75 million across six, Evove $12.95 million, Aqua Membranes $7 million, and Active Membranes stands at $3.24 million across two entries.

The difference is in what comes after the seed, and I ran the same query for every membrane company that has sat on this microphone, so the figure below carries the whole list, Membrion included at $43 million. Now, the two cases worth walking are the poles: ZwitterCo raised thirty times what Active Membranes did, most of it in one $58.4 million round in July 2024, to build capacity, while NALA, whose chlorine-tolerant polymer I wrote up in July, sits at six times and is still adding rounds in 2026. Active Membranes’ seed closed the same month as ZwitterCo’s big round, led by Natural Ventures with Echo River Capital and Pacifica Water Solutions, for $2.3 million per PR Newswire, 10 July 2024.

Can a $5 million last round still return 10x?

My objection on air was Echo River’s own thesis: Peter Yolles believes 10x, even 100x, is possible in water, and 10x in six to eight years means hypergrowth, so machines and footprint paid upfront, franchise or not. His answer: low capital makes the mistakes smaller and the path nimbler, and 2030 ends in profitability or an exit.

Let’s walk the arithmetic, which is not investment advice. A $5 million last round caps the total raised at roughly $8 million, not all equity since the first $3.2 million mixes in grants, so a 10x on the shares sold needs an exit well north of $80 million, how far north depending on the investors’ share. In water membranes that means a strategic acquisition, not an IPO, and Arian says so (“a good exit would be nice at some point”) in a market of five or so RO membrane producers keener, as I put it to him on air, to partner on outside tech than to invent it. So he sits on the seedstrapper end of my newsletter’s barbell.

What 2026 is testing: XPRIZE semifinals, Israel, and the home KFC

Active Membranes now offers its first standard 8-inch by 40-inch modules and has a seawater pilot lined up in Israel, both reported by Aquatech in November 2025, and on 12 May 2026 XPRIZE named it a semifinalist in both tracks of its $119 million Water Scarcity competition, one of 37 teams, with finalists due in 2027 and winners in 2028.

Now, Track A tests whole desalination systems, about 1,000 litres a day over two weeks, and Track B tests new materials at laboratory scale, so a company in both is claiming to be a system and a material at once, which is the franchise argument in prize form. Aqua Membranes is in the same semifinal, so the spacer route and the conductive route will be measured side by side. And Arian’s own list for the next twelve months was shorter: build the home KFC in California, make it replicable, and cultivate the partners in Israel, the Mediterranean and the Middle East, “wars and things permitting”. He had a line about the industry that I will let him say himself.

Frequently asked questions

What is membrane fouling?

Membrane fouling is the build-up of organic matter, biofilm and particles on the surface of a reverse-osmosis membrane, which raises the pressure the plant needs and lowers its output. Every part of a desalination plant upstream of the membrane, from pretreatment to the recovery it runs at, is designed to limit it.

What is the difference between scaling and fouling of membranes?

Fouling is the deposit of organic, biological or particulate layers on the membrane. Scaling is dissolved minerals, such as calcium sulfate (gypsum) or calcium carbonate, crystallising on it once their concentration passes what the brine can hold. Active Membranes’ electrical control targets the charged species behind scaling and biofouling.

How do you prevent membrane fouling?

Conventionally with pretreatment, antiscalant dosing, pH control and periodic cleaning-in-place. Active Membranes’ electrically conductive coating lets the membrane repel charged foulants at its own surface, which is how the Yuma pilot ran without antiscalant and with three cleaning events in nine months instead of nine.

Is membrane fouling reversible?

Partly: cleaning-in-place removes the reversible layers, but every cleaning means downtime, chemicals and wear, and repeated cleanings shorten a membrane’s life. That is why cutting nine cleaning events to three in the Yuma pilot is a lifecycle-cost number rather than a convenience.

What is the biggest problem with desalination?

In Arian Edalat’s operator view, scaling and fouling: they drive the chemicals, the footprint and the complexity that keep desalination uneconomic below communities of roughly 5,000 to 10,000 people, which is where most of the unserved demand sits.

What is seedstrapping?

Seedstrapping is my term for bootstrapping on grants and non-dilutive money until the first paying customers, taking one modest seed round, then stretching it toward profitability. Active Membranes, with about $3.2 million raised and a $5 million round planned as its last, and Uravu Labs are the worked examples.

Who invested in Active Membranes?

A seed round closed in July 2024, led by Natural Ventures with Echo River Capital and Pacifica Water Solutions, for about $2.3 million, plus a 2025-tagged extension of about $0.9 million in my Leviathan database. The total of about $3.2 million that Arian quotes includes grants and prize money.

What is the XPRIZE Water Scarcity competition?

A $119 million competition backed by the Mohamed bin Zayed Water Initiative to make seawater desalination reliable, sustainable and affordable. On 12 May 2026 it named 37 semifinalists, 20 in Track A (systems) and 17 in Track B (materials); Active Membranes is in both. Finalists come in 2027 and winners in 2028.

Where this goes next

So if the $5 million round really is the last one, 2030 is the date Arian set himself, and the XPRIZE finals in 2028 will come first, which means somewhere between the two we will learn whether a membrane company can grow on a franchise of $200-rig descendants. The full hour with Arian is in the player above, and the seedstrapping playbook is in my newsletter if you want it before your next board meeting.

The post Why Active Membranes Wants Its $5M Round to Be Its Last appeared first on (don't) Waste Water.

Uravu Labs makes water out of air, and yet what the Bangalore startup builds interests me less than what it decided: stop selling water as water. In atmospheric water generation, the cost of water is really the cost of heat, and Uravu’s own numbers make the point, at 2 cents a liter on grid electricity, 1 cent where the heat comes free. So instead of chasing the humanitarian market that swallowed $270 million at SOURCE Global alone, Uravu pays its bills selling premium water to hotels and breweries, roughly $1 million a year from one factory that sells over 80% of what it makes, and hunts the places where waste heat is free. The flagship target is data centers, a $569 million water-CAPEX market that will spill out close to a thousand terawatt-hours of heat by 2030. The question I want to walk through is whether hunting applications, rather than praying for cheap water, is how water-from-air finally becomes a business.

What is Uravu Labs known for?

Uravu Labs was founded in Bangalore in 2019 by engineers whose campus had run dry in 2016; co-founder and CEO Swapnil Shrivastav was one of five finalists in the $1.75 million Water Abundance XPRIZE, the only Indian team of the five, picked from 98 entrants (WaterWorld covered the 2018 finalist round). That prize asked for 2,000 liters a day at 2 cents a liter on renewable energy, a bar Uravu would chase for the next seven years.

The XPRIZE glory did what glory does: the first customers never came. They tried everything the “water for all” playbook prescribes, CSR budgets, NGOs, community devices, and nobody would carry a new technology’s risk. So they shifted gears, and the reset became the company, in Swapnil’s words: “today we sell the water… we don’t sell the technology”, to customers who already pay bottled-water prices.

An atmospheric water generator, to define it before judging it, pulls the moisture sitting in ambient air and turns it into drinking water, by cooling air below its dew point like a dehumidifier or by soaking moisture into a sorbent and releasing it with heat.

How much does atmospheric water generation cost?

Swapnil Shrivastav’s levelized cost curve for Uravu Labs, stated on my microphone in August 2025, runs from 10 to 12 cents a liter five years ago to 5 cents two years ago and 2 cents today, computed with grid electricity at 12 cents per kilowatt-hour, and 1 cent where the heat comes free. Levelized simply means the machine’s whole life is in the number, capital included.

Christopher Gasson, the publisher of Global Water Intelligence, famously called atmospheric water generation an “egregious waste of money”, and the numbers backed him, with desalination at 30 to 40% of its thermodynamic optimum and AWG near 5%. Swapnil doesn’t argue with the ceiling (water from air, he says, will not beat desalination for 10 or 15 years), so the question worth asking becomes “cheap enough for whom”.

And the curve explains the strategy: the drop from 12 cents to 2 came from engineering, while the drop from 2 to 1 comes from somebody else’s heat. Once you see that, you stop asking where water is expensive and start asking where heat is free.

The strategy: stop looking at water as just water

Uravu Labs runs two tracks at once, and the split is the strategy. Track one keeps the lights on: hospitality and beverage customers in Bangalore, an Italian-style microbrewery among the first believers, roughly $1 million in annual recurring revenue from a segment Swapnil honestly caps at about $10 million, served by a factory that pays itself back in under 24 months. He calls it the Tesla strategy (premium niches first while the technology matures), and over 80% of every liter made in two years was actually sold.

Track two is the bet, and he framed it with the line that gave this article its spine:

In practice that means hunting two or three markets whose own economics carry the water along, data centers and climate-controlled agriculture are the two he names, with a 2-meter cube that fits a standard 20-foot shipping container as the deployable unit. I covered where that discipline comes from in my newsletter on seed-strapping: too much cash, in his words, makes you solve problems by throwing money.

Do data centers really need water from air?

Data centers are the flagship application Uravu Labs is hunting, and the sizing goes like this: in 2025, Global Water Intelligence estimated the water CAPEX of data centers at $569 million for the year, cooling taking about 80% of it, while the International Energy Agency’s 2025 Energy and AI report projects data centers consuming around 945 terawatt-hours of electricity by 2030. Nearly all of that leaves the building as heat, and against that torrent, the projection I walked through in the episode editorial puts reused data-center heat at about 3.5 terawatt-hours a year by 2030. In the editorial I called it what it looks like: “not a gap, it’s a canyon”.

The 1 MW arithmetic

The expensive step of desiccant-based water-from-air is the heat that drives the water back out of the salts, and a data center manufactures exactly that all day long. By Uravu’s projections, feed the system a 45°C stream and you drop it to 30°C for each megawatt of waste heat used, collecting about 20 cubic meters of water a day. I fact-checked that claim in the episode: it works out to 0.83 liters per kilowatt-hour of heat, within the envelope of peer-reviewed efficiency figures, on the efficient end. And the output is distilled, which happens to be exactly what a cooling loop wants to drink (scaling and fouling, the two words every cooling engineer mutters in their sleep). I dissected the full thesis in my newsletter edition “VCs vs. Physics: Who Wins?”, and if you enjoy this kind of rabbit hole, that’s the one to subscribe to.

Where could the strategy break?

Swapnil Shrivastav supplies his own counterweight, and he does it better than the skeptics: asked when a data center actually runs on this, he answered that any integration at scale is realistically two years away, because data centers are critical infrastructure and nobody lets a Bangalore startup plug an experiment into a live cooling loop. In the companion newsletter I added two structural caveats of my own: operators “are here to play with Data, AI and cute pictures of babies stored on drives”, not to optimize exotic water tech, and “if heat networks take off, selling heat will always be a better monetary deal than selling water”.

The $497 million counterfactual

And picking the wrong application is not a hypothetical risk. I mapped the whole category in my Leviathan database: 32 companies carry the atmospheric-water-generation tag, with disclosed funding of $497 million. So let’s do the maths together: SOURCE Global, which sold hydropanels as a “water for all” play, raised $270 million by ESG Today’s 2022 tally ($223.8 million of it in rounds my database can see), and was declared dead in early 2025, four months before Uravu closed its fifth round. That one bet absorbed 45% of every disclosed AWG dollar, and with the other casualties added, 45.4% of the category’s lifetime capital now sits in dead or distressed companies. Colin Goddard, then SOURCE’s VP North America, had told me on this same microphone the goal was “the cheapest water on Earth”, and thermodynamics had other plans.

Is the smart money buying the strategy?

The data-center thesis reached Uravu Labs through its own cap table: about 18 months before our conversation, investor Peter Yolles of Echo River Capital kept sending Swapnil stories about data centers drinking whole towns’ worth of water; the founder went hunting, and the investor later cut a follow-on cheque. By late 2025 I counted nine AWG companies raising within the year, Echo River’s follow-on among them, in my “Four Questions About Source” edition.

Now the wallet-level evidence, from my Leviathan database again: Uravu’s syndicate has widened every full round, 5 investors in the 2021 pre-seed, 8 in 2022, 9 in 2023, 10 in the July 2025 round that funds the pilots, with $3.5 million disclosed (Inc42 pegged the total near $4 million in April 2023, so read that figure as a floor). And one stat I couldn’t resist computing: not one of SOURCE Global’s 17 backers, Gates, Bezos, Jack Ma, Masayoshi Son, Branson, BlackRock, appears on Uravu’s cap table. For the wider context, my State of Water Tech Funding 2025 has the full picture.

FAQ: the questions people actually ask

Do data centers use water?

Yes, mostly for cooling: Global Water Intelligence sized data-center water CAPEX at $569 million in 2025, cooling taking about 80%. Uravu’s angle is to flip the same problem around: use the heat side to produce water instead of only consuming it.

What is an atmospheric water generator?

A machine that harvests the moisture in air and turns it into liquid water, by chilling air below its dew point (the dehumidifier route) or by absorbing moisture into a desiccant and driving it out with heat. Uravu abandoned the first route after 1.5 years: below 50 to 60% relative humidity, it stops cooperating.

How do you make water from air without electricity?

Strictly speaking you don’t, but you can make it without dedicated energy. By Uravu’s fact-checked projection, a 45°C waste-heat stream dropped to 30°C drives the desiccant cycle at about 0.83 liters per kilowatt-hour of heat, landing near 1 cent a liter versus 2 cents on grid power.

Do atmospheric water generators really work?

They work; the honest question is where they make sense. The category runs near 5% of its thermodynamic optimum against desalination’s 30 to 40%, so pure drinking-water plays lose to wells, tankers and bottles almost everywhere. They earn their keep where quality or an allied application, cooling above all, carries the economics.

What is the revenue of Uravu Labs?

About $1 million in annual recurring revenue from the Bangalore consumer and hospitality business, a segment Swapnil himself caps at around $10 million, which is precisely why the company is hunting bigger applications.

Is Uravu Labs water safe to drink?

What leaves the machine is distilled water at near-laboratory grade (pH around 7, near-zero dissolved solids, in Swapnil’s words almost pharma-grade ASTM Type 3), which the company then supplies to hospitality and beverage customers.

What is the future of Uravu Labs?

Ten to fifteen replications of the Bangalore factory, a project deployed in Abu Dhabi, and data-center pilots targeted within 6 to 12 months, with integration at scale a couple of years out by the founder’s own estimate.

The two-year test

So, does the strategy hold? My honest read: the physics argument for waste-heat AWG is sound, the fact-check landed on the efficient-but-plausible end, and the funding pattern (small cheques, a widening syndicate, an investor who seeded the thesis) looks like conviction rather than fashion. But the strategy has written its own exam: within roughly two years, either a data center lets Uravu bolt onto its cooling loop, or the flagship application stays a well-argued pitch while hotels and breweries keep the company alive.

Swapnil, who at 29 calls himself probably the oldest person in his company, is spending the new round to force the answer, and he closed our conversation with an open call to data-center and climate-controlled-agriculture operators who want to co-create a pilot. And if you want to judge the bet yourself, listen to the full episode below, because the best due diligence in water tech is still hearing a founder argue against his own pitch.
