A 10,000-gal bioreactor operates at a biomass concentration of 2,500 mg/L (as MLVSS) and treats 13,000 gal/day liquid waste that contains an organic contaminant. The suspended solids are separated in a clarifier following the bioreactor with recycle of separated sludge. We know that at least 25 days of solids retention time is required for effective treatment of this waste stream. What is the recycle flow rate if 100 gal/day of the recycled biomass is wasted and the biomass concentration in the clarifier effluent is 20 mg/L MLVSS? Flow FIGURE 10-13 Flow and solids balance for system with recycle.
