Comparisons of Polymeric and Conventional Coagulants in Arsenic(V) Removal
The removal of arsenic(V) from water was investigated under various coagulation conditions and compared to a variety of coagulation agents, including polymeric ferric chloride, polymeric ferric sulfate, polymeric aluminum chloride, polymeric aluminum sulfate, ferric chloride, ferric sulfate, aluminum chloride, and aluminum sulfate. Coagulation conditions evaluated include pH, temperature, type of coagulant, the addition of a coagulation aid, and initial arsenic(V) concentration. Results indicated that the arsenic removal efficiencies of polymeric coagulants were typically 10 to approximately 20% higher than those of their conventional coagulant counterparts.
