Full Description

Jar tests were conducted to evaluate enhanced coagulation in California State project water (SPW), Colorado River water (CRW), and varying blends. During the six months of testing, SPW showed consistent amenability to enhanced coagulation treatment (maximum total organic carbon [TOC] removed however, at low coagulant doses and when poor flocculation and settling occurred, the model over-predicted TOC removal. The alum-adsorbable TOC varied by 50 percent in SPW and remained relatively constant in CRW. Includes 8 references, table, figures.
