RoQuest 6000

RoQuest 6000 is a liquid blend of dual organic coagulants and ferric sulfate used to reduce turbidity and remove humic and fulvic acids in multimedia filters. This product works well on waters containing high soluble organics and turbidites above 2.0 NTU. This multicomponent polymer and iron salt coagulant is formulated specifically for membrane use, including applications of surface waters that are both brackish and seawater in origin. Although this product is membrane compatible, overfeeding of pretreatment chemicals is not recommended as it can affect organic and particulate removal. RoQuest 6000 is also used as a coagulant and flocculant aid in flocculator-clarifiers and multimedia filters. RoQuest 6000 is NSF approved.
