| Contents Notes |
In existing biological wastewater treatment systems, the degradation and utilization of wastewater nutrients are controlled by complex enzyme systems. The objectives of this study were the biochemical fractionation, concentration, and evaluation of a lyophilized immobilized enzyme preparation for its effectiveness to enhance the biological degradation of domestic sewage. A method was developed to biochemically fractionate the microbial enzymes from activated sludge, to concentrate and characterize their activity, and to immobilize this activity by entrapment in a polyacrylamide gel. The enzyme-gel preparation was tested for its effect on the biological degradation of a bench-scale batch activated sludge process. |
