Abstract
The paper mentions some of the reported uses of Horizontal Flow Roughing Filters (IIRF) in drinking water treatment plants in Europe before briefly reviewing research activities carried out in the use of IIRF prior to Slow Sand Filters. Design, operation and maintenance aspects Of HRF are reviewed on the basis of the laboratory and field tests carried out in Tanzania and Switzerland, respectively in addition to experience gained in operation of a number of plants already built to date. Design aspects are introduced from the point of view Of its philosophy and optimization strategies before design guidelines are given. Important layout and construction details are also discussed. Operation and maintenance activities involved are outlined prior to reviewing economic aspects. At the end, conclusions regarding the viability Of application of HRE in rural water supply schemes and the need to combine the findings of all researchers are given.
