Slow sand filtration

摘要: This review will initially consider the history and early development of slow sand filtration process progress to examine present design in some detail also touch upon construction methods. Theoretical aspects be examined. Operation management dealt with, with cleaning resanding techniques being particularly considered. The advantages explored, especially simplicity operation ability remove potentially pathogenic organisms from water. Of disadvantages, it difficulties associated appreciably turbid waters that given most space although effects algal blooms investigated. Emphasis available for pretreatment source also, particularly, applicability developing world.
