Virus removal by coagulation and flocculation
In communities that are treating relatively clear water (turbidity less than 50 ntu), conventional water treatment processes have been modified by eliminating either the sedimentation process or the flocculation process. This modified system is referred to as direct filtration. Coagulant dosages used in direct filtration systems are much lower than dosages used in conventional treatment systems (less than 20 mg/L). It is therefore important to assess the effectiveness of coagulation and flocculation for virus removal at low coagulant dosages and also to determine the role of turbidity in the interaction between virus and the coagulants.
