Full Description

One method to improve the effectiveness of inorganic metal coagulants in water treatment is to partially neutralize concentrated metal salt solutions prior to their addition to the raw water and thus preform polymeric metal species, the actual coagulants. In this way coagulant chemistry can be controlled and proper solution conditions for the formation of desired coagulant species can be maintained. This article compares polymeric preparations of aluminum and ferric chloride salts with respect to preparation parameters and the extent and stability of polymerization. Includes 40 references, tables, figures.
