INFLUENCE OF CATIONS ON ACTIVATED-SLUDGE EFFLUENT QUALITY

The objectives of this study were to investigate the attachment or release of biopolymers resulting from changes in the calcium, magnesium, and potassium ions in activated sludge influent and to begin understand some underlying interactions of trivalent iron. The overall goals were to determine whether effluent quality could be significantly affected by changes in cations and, if these changes were obvserved, to show that they were related to variations in biopolymer binding.
