Abstract

Application of UASB method for wastewater treatment of canned fish factory reduces the costs of pre-treatments processes such as neutralization, and also reduced the costs of final aeration process. In this study, an UASB reactor which was equipped with a 3-phase separator system has been used. At first, a complex of anaerobic digester sludge and return sludge of activated sludge was added to reactor with ratio of 25 to 15. Then, the wastewater of factory entered into the reactor with inlet Organic Loading Rate (OLR) of 0.5 kg/m3.day which was increased gradually up to 4 kg/m3.day. Then, sampling was done for various tests during 75 days. The results of this study showed that UASB method neutralized and reduced the pH of the inlet wastewater from 10.5 to 7.3; and also reduced the SS of the inlet wastewater from 43 gr/l to 8 gr/l. the COD removal rate of this method was around 87%.

Keywords: canned fish wastewater, anaerobic treatment, UASB, COD, OLR.
