Cold Water Effects on Enhanced Coagulation of high DOC, Low Turbidity Water

摘要

Prairie farm reservoirs are usually low in turbidity and contain high concentra- tions of dissolved organic carbon (DOC). Some are treated with aluminum sul- fate in late fall when the water drops below 3 deg. C, of the with poor turbidity reduction results. Jar tests using aluminum sulfate were conducted to study the effect of water temperature on enhanced coagulation of a typical high DOC prairie water.
