【Abstract】 In this experiment the fiber ball is used as a filter medium for direct filtration of raw water.The results show that the fiber ball can effectively filtrate raw water of 50～150 ntu turbidities at 10～20 m·h -1 filtration velocity without any coagulant. Compared with sand filtration,the fiber ball filtration has good qualities of a higher velocity,a longer filter period and stability,thus creating a considerable economical benefit.更多还原
