ABSTRACT: A kind of environmental friendly novel composite
flocculants which are used to treat raw water is prepared. It is
made with chitosan (CS), iron modified polyaluminium chloride (CF-PAC) and modified
montmorillonite on the principle of “the combination of organic and inorganic”. Under
the optimum best compound formula and flocculation process, the turbidity of
the waste water reduced by 0.62%, the chemical cost decreased by 12.43% and the
content of aluminium ions dropped by 70.65%. There is an excellent characteristic and
higher efficiency on the composite flocculant which can adsorb the organic
matter in the water and chelate the heavy metal ions in the water.
