Mine Water Treatment: Coagulation/Filtration

TREATMENT TECHNOLOGIESPILOT TESTINGPUREFLOW COAGULATION/FILTRATIONPILOT TEST 1PILOT TEST 2COMPARISON TO ALTA RESULTSSUMMARYA cost-effective approach for arsenic removal is iron coagulation and precipitation followed by filtration, termed coagulation/filtration (CF). Common methods of coagulating arsenic and antimony are iron coagulation, alum coagulation and lime softening. Alum coagulation is generally less efficient than iron coagulation, so alum should only be used in systems with low arsenic concentrations, which is not the case at the Smith Mine.Accordingly, lime softening is a common technique used to preci.
