Denitrification kinetics of simulated fish processing wastewater at different ratios of nitrate to biomass

Denitrification was studied in anoxic batch cultures of a simulated fish processing wastewater at 37 r C and pH 7.5, using a denitrifying enrichment culture from fishery wastewater. Different initial nitrate to biomass ratios (So/Xo) were used: nitrate and biomass varied from 7.5 to 94.7 mg NO3-N l−1, and from 20 to 4300 mg volatile suspended solids l−1, respectively. The specific maximum denitrification rate (r m) and the cell yield (Y X / S) depended on the So/Xo ratio under anoxic conditions… CONTINUE READING
