Optimization of flocculation process for a new myco-coagulant to reduce water turbidity

The flocculation process to reduce turbidity from kaolin suspension by a new myco-coagulant was optimized. The results indicated that turbidity removal of 94% (from 650 NTU to 38 NTU within 5 minutes settling time) was achieved by a combination of rapid and slow mixing process. A sequential optim...
