(FOR LEAD TIME, PLEASE CALL +1 (800) 419-5707)

The Avista RoQuest™ 4000 Liquid Coagulant is a high-performance liquid coagulant formulated with a proprietary blend of organic polymers and ferric sulfate. Designed to enhance multimedia and sand filtration, it effectively removes a wide range of contaminants including inorganic particulates, organics, silt, and colloids—making it ideal for water with elevated turbidity and organic content. This advanced formulation improves filter efficiency by reducing turbidity and color, resulting in cleaner filtrate and helping to minimize fouling in downstream RO and nanofiltration systems.
