摘要: The removal of hepatitis A virus (HAV) and rotavirus (RV) from source water was studied by means laboratory pilot-scale treatment, including coagulation, filtration, softening. Poliovirus (PV) included as a frame reference because considerable data are available on the this during treatment. authors conclude that coagulation flocculation remove HAV RV effectively PV, with turbidity alkalinity having no influence extent removal. In addition, all three viruses were found to be efficiently removed Ca2+ Mg2+ hardness reduction at pH 11. Coagulation, settling, filtration in pilot plant lowered densities HAV, RV, PV 98.4-99.7 percent.
