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/m3/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/m3/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.
