Methods and systems for optimizing water treatment coagulant dosing |
| abstract |
Embodiments of the invention comprise methods and systems for optimizing coagulant dosing of raw water in a water treatment process. First, the embodiments determine the optimum dosage of pH adjusting chemicals to be added to the raw water based on a measurement of dissolved organic content, alkalinity, and pH of the raw water. Then, the embodiments perform a flocculation test of a mixture of the optimally-pH-dosed raw water and a hydrolyzing metal salt (HMS) wherein the dosage of the HMS salt in the mixture can be calculated based on a measurement of the charge demand of the optimally-pH-dosed raw water. The results of this flocculation test are compared to the results of at least one previous test of a combination of optimally-pH-dosed raw water and HMS to determine if the hydrolyzing metal salt dose is optimized. Once the HMS is optimized, the optimally-HMS-dosed optimally-pH-dosed water is tested with at least two different dosages of a polymer coagulant to determine the optimal polymer coagulant dosage to be used with the optimally-HMS-dosed optimally-pH-dosed water. |
