This slide presentation outlines a study on optimizing mixing for coagulation and flocculation. The objective of rapid mix includes: rapidly and uniformly distributing coagulant chemicals into the process flow stream. Topics outlined include: rapid mix guidelines; rapid mix types; mechanical mixers and rapid mix basins; in-line jet mixers; in-line mechanical mixing and static mixers; hydraulic mixing; potential rapid mix problems; indications of potential problems; examples of rapid mix improvements; flocculation objectives; flocculator types; vertical shaft impeller types; recommended flocculation criteria; possible flocculation problems; examples of flocculation improvements; calculate vertical impeller power input; calculate horizontal paddle wheelpower input; calculate vertical impeller G value; and, significance of G calculations. Includes tables, figure.
