Potential of using bio-coagulants indigenous to Malaysia for surface water clarification

Water treatment processes in developing countries typically include coagulation and flocculation and often use alum as the coagulant. Coagulation is a critical step in drinking water treatment because of removing the colloidal particles as well as pathogens that are often attached to the particles....
