Development of coagulation theory and new coagulants for water treatment: its past, current and future trend

This paper reviews the history of chemical coagulation and its effects on the water quality control and management, considers how the most favourable coagulant species and prepolymerised inorganic coagulants may be prepared by reference to the appropriate coagulant chemistry, and evaluates the overall performance of some pre-polymerised coagulants in comparison with that of conventional coagulants for water treatment.
