Abstract

Untreated waters usually contain tinely divided matter which must be removed before distribution for domestic and industrial use. Although the bulk of such material is neither toxic nor pathogenic, safety and aesthetics dictate that all potable water be essentially free of suspended matters. Destabilization of suspended particles by coagulation so that they may be removed by sedimentation and filtration is important in the process of clarification. When the removal of suspended solids from unsoftened surface waters is the primary objective of treatment, coagulation is necessary. There are various methods available to control this unit process, each one suffering from one difficulty or another. A new method which shows promise in overcoming these difficulties is the colloid titration technique. The purpose of this research is to investigate the application of this method on Lake Michigan waters.
