The role of coagulation in water treatment - ScienceDirect

The modern use of coagulants for water treatment started more than 100 years ago, when ferric chloride and aluminum sulfate were used as coagulants in full-scale water treatment works. The coagulation mechanism was firstly explained by the Schultz–Hardy rule and the Smoluchowski's particle collision function, which form the theoretic basis of
