Pilot Studies on Cloth Media Filter Applied in WWTP for the treatment of Secondary Effluent
Cloth media filter was applied in the treatment of the effluent of a municipal wastewater plant through pilot scale test for water reuse. Ferric chloride (FeCl3), PAFC and polyaluminum chloride (PAC) were employed as coagulants respectively to carry out the test. The average removal efficiency of TP and CODo was 28.76% and 8% after cloth media filter without coagulation, and TP removal was influenced by the influent water quality. However, precoagulation with coagulants of ferric chloride, PAFC, PAC, the average removal efficiency of TP was 63.58%, 60.13%, 66.94% respectively, and no influence of TP removal can be found by the influent water quality. The average removal efficiency of CODCr was increased to 17.7%, 26.3% and 27.7%. TN was removed unstably after cloth media filter.
