Filtration behaviors of Giardia and cryptosporidium-ionic strength and ph effects

摘要

The laboratory-scale filtration tests of Giardia cysts and Cryptosporidium oocysts in both 2 mm- φglass beads and 2 mm-φ polystyrene beads filters were conducted to investigate their filtration behaviors. The protozoan parasites were used as target particles, while the chemical system altered by changing the Electrolyte concentration and pH. The results significantly indicate that ionic strength have positive effect On the removal efficiencies for Giardia cysts and Cryptosporidium oocysts.
