No batteries required – “For clean water, just add sunlight … “

Chemistry World reported in an article on 26 June 2012 about a potential use for rural applications, “Researchers from Japan have developed a photocatalytic reactor for a water purifier that does not require batteries. Rather than using an external power source to pump water through the reactor, the system uses diffusion and capillary action to achieve an entirely non-electric reactor.”

Contents:
This book is dedicated to various water treatment processes. Water treatment describes those processes used to make water more acceptable for a desired end-use. These can include use as drinking water, industrial processes, medical and many other uses. The goal of all water treatment processes is to remove existing contaminants in the water, or reduce the concentration of such contaminants so the water becomes fit for its desired end-use. One such use is returning water that has been used back into the natural environment without adverse ecological impact. Measures taken to ensure water quality not only relate to the treatment of the water, but to its conveyance and distribution after treatment as well.[As taken from Syndetics]

The definitive guide to the theory and practice of water treatment engineering.This newly revised edition of the classic reference provides complete, up-to-date coverage of both theory and practice of water treatment system design. The Third Edition brings the field up to date, addressing new regulatory requirements, ongoing environmental concerns, and the emergence of pharmacological agents and other new chemical constituents in water.Written by some of the foremost experts in the field of public water supply, Water Treatment, Third Edition maintains the book’s broad scope and reach, while reorganizing the material for even greater clarity and readability. Topics span from the fundamentals of water chemistry and microbiology to the latest methods for detecting constituents in water, leading-edge technologies for implementing water treatment processes, and the increasingly important topic of managing residuals from water treatment plants.[As taken from Syndetics]
