Abstract

Evaluates the validity of the filter to waste procedure by plant-scale investigation of initial filter effluent quality and pilot-plant study of filter-ripening mechanisms and backwashing techniques that improve initial effluent quality. Also describes quality of initial filtrate, presents guidelines for minimizing degradation of postbackwash filtered water quality, and discusses whether a filter to waste period for treatment plants is warranted.
