PERFORMANCE EVALUATION OF UASBR FOR MILK PROCESSING PLANT OF S.R.THORAT MILK PRODUCTS PVT.LTD AT RAJAPUR

This work was aimed to evaluate the performance of UASBR for treating milk processing wastewater. The study has been conducted for the UASBR installed at S.R.Thorat Milk Products Pvt. Ltd. at Rajapur, Tal. Sangamner, District Ahmednagar. The organic loading rate was 3.69 Kg COD/m3/day, hydraulic retention time was 10 hours, and flow rate was 10m 3/hr. And up flow velocity was 0.6m/hr. The COD: N: P ratio was followed as 100:5:1 for nutrient feed. The performance of UASBR is reported in terms of % removal of various wastewater characteristics by UASB process. It is observed that the biogas yield of 0.6m3/m3reactor volume/day is sufficient to carry out natural mixing in the reactor. So Upflow Anaerobic Sludge Blanket (UASB) reactor can be suitable alternatives for treatment of such wastewater to reduce overall operational cost of the treatment. [2
