Optimal Use of Ozonation and GAC in Direct Filtration for Drinking Water Treatmented. A comparison of preozonation followed by GAC filter media to post-filtration ozonation followed by a GAC contactor is made based on various aggregate measures of organic matter including DOC, THMFP, HAAFP, AOC and odors. The results show that ozonation and biologically active GAC media improve o

The Use of Polymer in the Pre-precipitation Step of a Wastewater Treatment System for Extended Nutrienitrification in a single sludge activated sludge system. As the nitrogen removal at the plant is strongly affected by the sludge age, the capacity of the system should be increased if the load of particulate material on the biological treatment is decreased..In order to improve the suspended solid

Membrane permeates were of similar or better quality than filtrates from the plant’s conventional sand filters. Good removal of particulate contaminants, including coliform bacteria, was observed. In comparison with the

Preliminary laboratory and pilot-plant experiments were undertaken to evaluate the performance of PFS, in comparison with conventional coagulants such as ferric sulphate (FS), for the coagulatio
