Treatment of surface water sources with a high degree of eutrophication requires special
measures. Since filtration is the last unit operation in any given treatment train to remove
colloidal and particulate matter from the raw water source, its importance is very relevant to the
production of drinking water which meets current potability criteria. Polymer addition in the
coagulation step can benefit the filtration step greatly. The polymers employed in the treatment
of water supplies as filtration aids have been of the high molecular weight type, anionic or nonionic.
This work focused on assessing the utilization of cationic polymers as filter aids, thus
looking into a new option for drinking water treatment. Since there is not yet a consistent
theoretical basis to make it possible to determine the ideal polymer type and corresponding
optimum dosage for a given treatment train and raw water source, the only way to establish
parameters towards rational polymer is to conduct systematic and extensive laboratory and pilot
scale testing. Includes 6 references, tables, figures.
