KOAGEN 215
DESCRIPTION
KOAGEN 215 is a liquid blend of polymerised aluminium salt used as coagulant in raw and wastewater treatment.
KOAGEN 215 works in a wider range of pH compared to aluminium
sulphate. It is effective from pH 5 to 10.
KOAGEN 215 lowers pH and alkalinity less than that of alum and
iron salts thus reduces the need for post pH adjustment. It, therefore,
saves costs on alkali consumption.
