Chemical Coagulation Dosage Control.
Abstract
The purpose of this investigation was to determine if the best dosage for various coagulants would be the same if a number of indicators were used as the best dosage criteria. Specifically, what is the indicated best coagulant dosage between zeta potential, colloidal titration, apparent color, true color, COD reduction, turbidity reduction, and bacteriophage reduction. Two types of water were used to empirically determine the above relationships. The first water was a secondary wastewater treatment plant effluent; the type of wastewater that may be delivered to an advanced wastewater treatment system. The other water was a relatively unpolluted raw surface water; the type of surface supply that is often used for a potable water supply. The results of this investigation, after testing with nine different coagulant/coagulant aid combinations, revealed that the best dosage varies as a function of the indicator used to determine that dosage.
