A clear solution for dirty water

Abstract

Worldwide, as many as 2 billion people drink water that could be harmful to their health because of the presence of parasites, bacteria, viruses, or heavy metals. Now household products company Procter & Gamble has added a new weapon to the point-of-use water treatment arsenal. As part of its Children's Safe Drinking Water Program, the company has developed PUR™, a simple new method to purify drinking water. Each packet of PUR - which consists of flocculant agents and powdered bleach - can purify up to 10 liters of water. Within 20 minutes, even muddy water is cleared of suspended particles, microbes, and other toxicants.
