Water Treatment and Wastewater Treatment are complex fields. Have you ever met someone that told you, he was fully confident to know everything about them? Well spoiler: that person lied 😀

But don’t worry, by patiently compiling (and never stopping!) all the questions I hear left and right, then looking for the best experts to answer them, I’ll build a definitive Water Industry cheat sheet for you right here.

About How Long have Wastewater Treatment Plants been in Existence?

The timelines of Water and Wastewater Management started around the same milestones, with the first large civilizations.

Around 3’500 BC, the first evidence is found of Water & Wastewater Management in the Mesopotamian Empire.

The Romans would then be the first to provide a full circle integrated water cycle management.

And then… nothing!

With the collapse of the Roman Empire, everything that the Mesopotamians, the Indus, the Greeks, or the Romans had brought to human wellbeing kind of vanished.

Water would recover, gradually. But for wastewater… the dark age would last over a millennial!

Dive into the depth of that story here, to answer this simple question: how long do Wastewater Treatment Plants exist?

Who are the most influential people in the Water Industry?

This exercise is for sure very subjective, yet here’s my attempt:

5️ The Man who defied a US President
4️ The Water Detective that triggered an Industry Revolution
3️ The Man that triggered desalination – and got a dismal reward
2️ The Man that made Drinking Water “Pure and Wholesome”
1️ The Technology, that’s somehow in my garden

To clarify my choices (a little), I also give you the list of people that were close to making it towards the end of this deep dive!

What is a Membrane Bioreactor?

It is the most rapidly growing wastewater treatment technology and has the power to turn a secondary treatment into an almost quaternary one.

Yet, 25 years ago, early pioneers were seen as slightly mad to believe, Membrane Bioreactors could become a thing!

At the times, membranes already had difficulties establishing themselves in clean water applications, so you can imagine that in wastewater it was even worse…

What’s the secret of MBRs? We’ve made a thorough tour of the question (… and if there’s something missing, please reach out!)

What is Membrane Filtration?

As we’ve just seen, membrane treatments grew in 30 years to a dominant water treatment technology (almost from scratch). Yet, do you know everything about them?

I strived to put all the key knowledge about membrane filtration in a single place so that you’ll know the ins and outs of microfiltration, ultrafiltration, nanofiltration, reverse osmosis, and all their friends!

What is Ozone Water Treatment?

They may well be around for 120 years, but ozone plants are still a riddle to many.

Killer Gas? Killer Song? We investigate all of this in this ozone water treatment deep dive.

In short, ozone is tri-oxygen, an unstable form of oxygen that happens to be one of the most powerful oxidants on earth.

You can produce it by breaking dioxygen through UV radiation or electrical shocks.

… and once introduced into water, it may disinfect, purify, remove specific pollutants (and much more).

So, did you know:

🍏 … that the “Ozone Layer” is almost a fraud?
🍏 … that the guy that discovered Ozone actually did not notice?
🍏 … that 19th-century hipsters saw the gas as a source of wellbeing?
🍏 … that the First World War almost killed ozone treatments?
🍏 … that it took the discovery of Four Horsemen to revive the ozone hype in the 1970s?
🍏 … that one of the major improvements of ozone generation resulted from another lab accident?
🍏 … that history was made both in the South-West of Germany and in LA?
🍏 … And that you can find ozone quite easily around you if you’d like to experience it first-hand?

No? Then you’ll love the video summary you’ll find here.

What is Singapore’s Secret to Nail Water Treatment?

Water is integral to Singapore’s success, and it is not a coincidence. Since the country took its political independence from Malaysia, it conscientiously built its water independence as well!

This water management marvel will be over in 2060 when Singapore cuts the last cord that still ties it to Malaysia, and it involves water reuse, the most advanced water treatments, and gigantic water infrastructure.

How does that work in detail? You’ll find out in this deep dive!
