TANNIN-BASED POLYMER AS FILTER AID FOR REDUCING FOULING IN FILTRATION OF HIGH TDS WATER |
摘要 |
The present invention concerns a method of reducing fouling and increasing the efficiency of microfiltration and ultrafiltration systems by adding an effective amount of a tannin-based polymer to wastewater containing high concentrations of total dissolved solids (TDS), such as produced water, prior to filtration. Additional pretreatment to separate out and remove coagulated solids before filtration is not required. Typically, the tannin polymer used in treating the process water is a modified tannin comprised of a Mannich reaction product of an amine, an aldehyde, and a tannin. |
