✦ Synopsis

Anaerobic treatment of wastewater from a selected seafood processing plant was conducted at organic loading rates (OLR) ranging from 0.3 to 1.8 kg chemical oxygen demand (COD)/m3.day and hydraulic retention times (HRT) ranging from 36 to 6 days. COD reduction decreased with increasing OLR. More than 75% COD reduction could be maintained up to an OLR of about I kg COD/m3.day with an HRT of 11 days. An OLR of 1.3 kg COD/m3.day corresponding to an HRT of 6.6 days gave maximal biogas productivity of 1.5 m3/m3.day or 1.3 m 3 biogas/kg COD with a 65% COD reduction. If the HRT was kept constant at 11 days, an OLR of 1.3 kg COD/m3.day achieved maximal biogas productivity (1.1 m3/m3.day) and yield (0.75 m3/kg COD) and a 60% COD reduction for treatment of tuna condensate.
