RoQuest® 3000 liquid coagulant contains a proprietary blend of organic polymers that works best on waters with hard silt based colloidal particulates. This multicomponent polymer coagulant is formulated specifically for membrane use, including applications of particle-laden borehole sources or treated municipal supplies that are used for industrial or drinking water. RoQuest 3000 is injected into the feedstream of multimedia and sand filters, where it enhances filter performance by reducing turbidity and color. Therefore, producing an improved filtrate that will reduce reverse osmosis (RO) and nanofiltration (NF) membrane fouling downstream.
Best results are achieved with municipally treated feedwaters and raw waters that contain relatively low concentrations of particulates and organic color. In raw waters, the upper limits of turbidity and color for this product are 2.0 NTU and 10 units, respectively.

Performance Benefits:
- Filter-aid properties resist solids breakthrough in direct filter applications.
- Low dosage requirements and no minimum alkalinity.
- Internal biostat inhibits biological growth in the drum and feed tank.
- Effective over a wide pH range.
- Capable of producing RO quality feedwater in multimedia and sand filters.
- Compatible with polyamide and cellulose acetate RO membranes and Avista antiscalants, including Vitec® 3000, 3025, 5000, 5100 and 7000.
