One company is leading the way in membrane technology that actually turns sewage into drinkable water.

While this sounds like something far-fetched (and certainly not anything you’d actually want to drink), Bloomberg Business recently interviewed Snehal Desai, Global Business Director for Water & Process Solutions at Dow Chemical and Minneapolis Chapter President for The CMO Club, to get a closer look at how the process works.

You’ve probably heard of water filtration systems that purify waste, making it reusable for crop and lawn irrigation. Well, Dow’s toilet-to-tap system takes it one step further in a more rigorous process that relies on membranes – not chemicals – to purify sewage water.

Why sewage? Can’t we find water from somewhere else?

Desai explains that most of the water we are drinking isn’t naturally pure to begin with, and may have started off as waste that was purified and dumped back into a river or ocean. Dow’s special membrane – which is finer than a human hair – has perfected the water purification process to deliver cleaner water than most systems and sources that we rely on today.

“Even cleaner than some bottled waters,” he said.

As water shortages increase around the world, cities and states are looking for a more reliable way to get water to their residents. Experts like Desai believe membranes are the answer and will be the future of clean water sources.
