Ranking trend among the optimal coagulants is the same in Processes I and II. Irreversible and reversible fouling mitigation trend is the same for both Processes. Coagulant equilibrium concentration and coagulant dosage are largely inequivalent. Reversible fouling alleviation is primarily responsible for fouling mitigation.
