Water treatment (continued)

Another type of low cost treatment plant for small towns is based on the gravity flow slow sand filtration process, a technique first developed in the UK some 150 years ago. Pilot studies to test the suitability of the process under local conditions have been successfully undertaken in Victoria by the Rural Water Commission in recent years. Based on these studies a full scale demonstration plant has now been completed to service a population of approximately 200. This process could provide a low cost alternative to more conventional treatment plant, since it uses no chemicals and omits the clarification step.

A unique method of water treatment, the 'Sirofloc' process, was developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Clarification involves the magnetization of particulate matter, which aggregates and settles rapidly, so the clarifier is much smaller than in the conventional plant. There is no filter and the clarifying agent can be re-used. The advantages of this Australian invention over a full-scale conventional plant are lesser capital cost, low head loss across the plant, and much less sludge for disposal.
