China - ‘Toilet-to-tap’ coming to China, professor says

WASHINGTON DC — In 2010 China will embrace “toilet-to-tap” water treatment technology, predicts Xia Siqing, an environmental science professor at Tongji University in Shanghai and former visiting professor at Arizona State University, according to a Feb 20 story on Environmental Science Technology Online News.

Professor Xia is experimenting and testing “toilet-to-tap” purification techniques with a small-scale 105-gallons-per-day (400-liter) treatment plant housed in the university’s College Environmental Science and Engineering lab building.

Although Xia insists the reclaimed water is pure enough to be used for kidney dialysis, washing carbon-chips, and replenishing drinking-water supplies, according to the article, the water is actually reserved for use in laboratory experiments and local irrigation.

A second demonstration project of Xia‘s “toilet-to-tap” purification system is scheduled for the Shanghai World Expo to be held in 2010.
