A new kind of filter media, zeolite, is used to enhance filtration for an improvement on tap water quality. The experimental results show that zeolite can remove not only turbidity but also ammonia-N and partial organic pollutants in water. In the experments, zeolite can remove about 65% of turbidity and over 10% of COD Mn , 95% of ammonia-N from water, the removal efficiencies of anianon detergent(LAS), chloroform and phenol are over 17.7%, 44.45% and 34% respectively, and metal ion contamination has not been found in filter effluence. Therefore, zeolite enhanced filtration is an efficiency and security method for an improvement on water quality.
