A STUDY ON EFFECT OF VOLATAILE FATTY ACID ON ANAEROBIC BIO FILM REACTOR USING DAIRY WASTEWATER
In recent decades the use of anaerobic biofilm reactor has been established for the treatment of different effluents. As the capability of retaining microorganisms was act as biofilm factor influencing the performance of this reactor. The present study aims to evaluating the effectiveness of treating a dairy effluent with high pollution potential. The effluent was analyzed with varying Organic Loading Rate (OLR) 0.1502, to 0.266 kg COD/ m3/day, with an average value of Volatile Fatty Acid (VFA) of 172.8, 132.0, 193.0, 203.0and 172mg/L. The maximum COD removal efficiency of 84% along with production of 0.048m3/kgCOD of biogas at 3 days Hydraulic Retention Time (HRT) was observed.
