Abstract

The present study aims to determine the effects of the parameters that influence the coagulation/flocculation process as well as determine the optimal levels to be used in the optimization process using a myco-coagulant produced in solid-state fermentation for water treatment. Mixing speed, mixing time, the dose of myco-coagulant, initial turbidity, and time of settlement were examined through the one factor at a time (OFAT) approach. The factors were required to be tested further to choose the three levels required for the optimization process. The result obtained from the OFAT study indicated that the highest turbidity removal was observed at 10 ml/L of myco-coagulant dose, the optimal flocculating activity rate (%) is respectively rapid mixing at 200 rpm for 1 minute and slow mixing at 90 rpm for 22 minutes. On the other hand, the myco-coagulant showed good performance with increasing turbidity up to 800 NTU (92.22 %). The flocculating activity rate increased as settling time increased and stayed stable after one hour. The most influential parameters selected from OFAT will be subjected to the optimization process in order to achieve high flocculating activity. Based on OFAT experiments, FCCCD will be employed to determine the optimal conditions of the significant factors.
