The Effect of Hydraulic Retention Times and Loading Rates on the Removal of Pollutants from Fish Processing Wastewater by Anaerobic Process

Year: 2018

Type: article

Abstract: Anaerobic treatment model treats fish processing wastewater to be necessary for a small and medium factory that is very popular in Vietnam and other countries.Several techniques have been proposed.However, they are quite expensive and hard to operate, especially in remote areas.In this study, the hydraulic retention times (HRT) including 3, 5, and 7 hours with a various organic loading rate of 1.5 to 6.5 kg COD/m 3 /day were investigated.Biomass concentration as mix-liquor volatile suspended solid (MLVSS) in the model is at 6,000 to 9,000 mg/L.On the basis of the result the optimal HRT with a 4.0 kg COD/m 3 /day organic loading rate was 8 hours which BOD5, COD removal efficiency were 92.18, 87.36 percent respectively.By the end of the optimal hydraulic retention times, the total methane gas volume as a by-product was collected with 2.6 liters.
