Performance of Vinyl Core Media Trickling Filter Plant for Secondary Treatment of Municipal Wastewater
Zeitschrift fur Wasser und Abwasser Forschung
A full scale vinyl core media trickling filter plant was evaluated to determine its effectivess in removing pollutants from municipal wastewaters. The treatment plant is located in Zanesville, Ohio, and discharges its treated effluent into Muskingum River. TSS (total suspended solids), and BOD (biochemical oxygen demand) in wastewaters for different stages of treatment for a 9-year period from 1975 to 1983 are used in the determination of treatment performance. Results indicate that vinyl core media trickling filter plant can be used effectively as a secondary treatment process for the muncipal wastewater. The removal efficiency for TOC and BOD was about 90%. The TSS and BOD concentrations in the wastewater decreased as degree of treatment increased. The river has greatly diluted the treated effluent to a concentration of about 0.1 mg/l for TSS and BOD throughout the year.
