SYNTHETIC DAIRY WASTEWATER TREATMENT USING CROSS FLOW MEDIUM TRICKLING FILTER

摘要

The treatment of synthetic dairy wastewater was carried out using cross flow medium trickling filter of specific surface area 243 m~2/m~3. The operating variables in this study were hydraulic and organic loading rtes. The hydraulic loadings employed in this study were 5,9,13 and 17 m~3/m~2.d for the influent COD concentrations of 427 to 1384 mg/1. It was observed that the relationship between organic removal rate and organic loading rate showed two regions of linear behaviour with the point of inflection at an organic loading rate of 26 g COD/m~2.d. Kornegay model was used to evaluate the kinetic coefficients for the system. The results were found to be satisfactory.
