RoQuest™ 4000
RoQuest™ 4000 liquid coagulant is an organic polymer and ferric sulfate blend used to enhance the removal of a broad spectrum of inorganic particulates, organics, silt, and colloids in multimedia filters. This multicomponent polymer and iron salt coagulant is formulated for waters with high organics and turbidites higher than 2.0 NTU. Although this product is membrane compatible, overfeeding of pretreatment chemicals is not recommended as it can affect organic and particulate removal. 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. RoQuest 4000 is NSF approved.
