Polymer dosing is simple in theory, but complex in practice. The wrong polymer can stabilize the suspension and make the problem worse. Extensive jar testing is mandatory before proceeding with full-scale. Also, you need high-quality make-up water that I'm guessing might not be available. It's probably not economically feasible in this case, either. Dry floc systems run at least $100k, plus the ongoing cost of the reagent. Let's not even mention the logistics of getting any of this stuff in Haiti. That said, it is still a much better suggestion than microfiltration or ultrafiltration...in Haiti.
