1 Repeat the procedure of precious tests, the concentration of HA should be changed to 15mg/L. New lowest effluent turbidity vs coag concentration graph should be obtained.
2 After graining the optimal coag dosage for three different HA concentrations, a mathematical model should be able to created. The team should try to find the initial trend.
3 Advices may be needed if there is no trend for optimal coag dosage vs HA concentrations.
