| Abstract: | The chracteristics of Cryptosporidium parvum oocysts and their harm on humans were introduced.The influences of pH, coagulant types and doses, conductivity and the concentration of natural organic material on the zeta potenital of Cryptosporidium parvurn oocysts were analyzed. The removal effects of Cryptosporidium parvum oocysts by flocculation-sedimention-filtration and direct filtration were summarized. The influences of water temperature, water quality, coagulant types and doses, filter media, filtration rate on the removal effect were discussed. |
