A physico-chemical water treatment system for relief agencies.

The article presents information on the physico-chemical water treatment system for relief agencies. A physicochemical water treatment system was developed which has a minimum of power and mechanical plant requirements. The system comprised a pump driving the raw water supply through a spiral pipe flocculator and an upflow clarifier of novel new design fabricated within a standard Oxfam TII tank. This system was intensively tested and developed in Great Britain in a joint Department for International Development and Oxfam-funded research and development project.
