It is stabilized to prevent off-gassing, which makes it suitable for indoor installations, and it is more resistant to air oxidation than typical bisulfite liquids, improving shelf life stability. It removes chlorine more effectively than activated carbon beds and eliminates carbon bed problems including bacterial growth and carbon fines in downstream feedwater.\u003c\/p\u003e\u003cp\u003eKuriverter AC-427 is dosed neat into RO feedwater upstream of the membranes, either as a replacement for or an alternative to an activated carbon bed. It is formulated to be injected undiluted and should not be diluted for use. Published use rates are 6 mg\/L of neat product per 1 mg\/L of free chlorine and 8.2 mg\/L per 1 mg\/L of combined chlorine as monochloramine. Kurita recommends multiplying the calculated feed rate by 1.2 to apply a 20 percent safety factor, and confirming chlorine removal by direct chemical analysis.\u003c\/p\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e5 Gallon Pail (45 lb) (Item RT0050-5)\u003c\/li\u003e\n\u003cli\u003e55 Gallon Drum (500 lb) (Item RT0050-55)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eModified odorless liquid sodium bisulfite formulation, stabilized against off-gassing\u003c\/li\u003e\n\u003cli\u003eRemoves both free chlorine and combined chlorine (monochloramine)\u003c\/li\u003e\n\u003cli\u003eDose 6 mg\/L per 1 mg\/L free chlorine; 8.2 mg\/L per 1 mg\/L combined chlorine\u003c\/li\u003e\n\u003cli\u003eAppearance clear to yellow liquid; pH 5.0 to 6.4 at 20 C; complete water solubility\u003c\/li\u003e\n\u003cli\u003eSpecific gravity 1.10 to 1.35; freeze point 32 to 36 F (0 to 2.2 C)\u003c\/li\u003e\n\u003cli\u003eMore resistant to air oxidation than typical bisulfite liquids\u003c\/li\u003e\n\u003cli\u003eNSF\/ANSI 60 approved where RO permeate is intended for potable or drinking water use\u003c\/li\u003e\n\u003cli\u003eCompatible with polyamide membranes from all major manufacturers\u003c\/li\u003e\n\u003cli\u003eCompatible with stainless steel, Hastelloy, Viton, Neoprene, Kynar, Nylon, polypropylene, PTFE and polyethylene\u003c\/li\u003e\n\u003cli\u003eNot compatible with copper, brass, mild steel or aluminum\u003c\/li\u003e\n\u003cli\u003eStore above 41 F (5 C) to prevent seed crystal formation; 12 month unopened shelf life at 45 to 100 F\u003c\/li\u003e\n\u003cli\u003eInjected neat - do not dilute before use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRO feedwater dechlorination ahead of polyamide membranes on chlorinated supplies\u003c\/li\u003e\n\u003cli\u003eDrinking water RO systems requiring NSF\/ANSI 60 certified additives\u003c\/li\u003e\n\u003cli\u003eIndoor installations where bisulfite off-gassing odor is objectionable\u003c\/li\u003e\n\u003cli\u003eReplacement for activated carbon beds troubled by carbon fines or bacterial growth\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kurita America Inc","offers":[{"title":"5 Gallon Pail (45 lb)","offer_id":52873023193399,"sku":"RT0050-5","price":163.8,"currency_code":"USD","in_stock":true},{"title":"55 Gallon Drum (500 lb)","offer_id":52873023226167,"sku":"RT0050-55","price":1240.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/RT0050.jpg?v=1787259962","url":"https:\/\/www.blacklabelsupply.io\/products\/avista-kuriverter-ac-427","provider":"BLACK LABEL","version":"1.0","type":"link"}
