Toilet-to-tap Process Turns Water from “Nasty” to Nourishing

Dow scientists work to find the best methods to make water clean enough to drink

What flows from our membranes is essentially the Rolls-Royce of municipal water.

After a day spent basking in the sunshine of Orange County, California, you head inside to pour a cool glass of water from the tap. What you taste is clean, pure and refreshing. You’d never know that just weeks ago that water was … sewage? Really?

You can’t be blamed for thinking this idea far-fetched – or even a little gross.

And as sou...ties and companies are increasingly realizing the economic value of clean water,” said Andrew Liveris, Dow chairman and chief executive officer. “That’s driving growth in Dow’s water business at two times [the rate of] the global GDP.”

“What we’re perfecting at a large scale, for big centralized plants, may become affordable and effective enough to use in a decentralized system, household by household,” he said. “[This way], we each control and regenerate our own water supplies.”
