Kurita RoQuest - Model 4000 - Liquid Coagulant - Datasheet

RoQuest 4000 liquid coagulant is an organic polymer and ferric sulfate blend used to enhance the removal of a broad spectrum of inorganic particulate, organics, silt, and colloids in multimedia filters. This multicomponent polymer and iron salt coagulant is formulated specifically for membrane use, including applications of surface waters that are brackish or seawater in origin. RoQuest 4000 is injected into the feedstream of multimedia and sand filters to enhance filter performance by reducing turbidity and color to produce an improved filtrate that will reduce downstream reverse osmosis (RO) and nanofiltration (NF) membrane fouling. Best results are achieved in raw waters with upper limits of turbidity and color (10 NTU and 10 units, respectively) or in feedwaters where organic polymers have been under or overdosed.
