THE IMPACT OF RESIDUAL COAGULANT ON DOWNSTREAM TREATMENT PROCESSES

摘要

A series of jar tests were undertaken to optimise for suspended solids (SS) and phosphorus removal from raw wastewater. The residual metal concentration in the setled wastewater from the jar test experiments and the residual concenration from The optimum doses plus two higher doses were selected for investigation. The identified levels of residual metal were fed into A four lane activated sludge pilot plant to investigate the impact of metal concentration on (I) activated sludge performance And (ii) sludge production and characteristics.
