- activated sludge effluent
- The trickling filter and activated sludge efficiencies cited required primary sedimentation and effluent circulation.
- The experimental results showed that the raffinate after dilution of 15 times could be treated by activated sludge process,and theCOD value in the final effluent could meet the discharge standard.
- Over 300 strains of bacteria have been found in activated sludge.
- Acetate was degraded by denitrifying activated sludge.
