It uses a proprietary blend of dispersants, low foaming surfactants and chelants, and is highly buffered to resist pH change during cleaning. It is particularly effective on humic and fulvic organics arising in surface waters, and is suitable for nanofiltration and other membranes with lower cleaning pH limits.\u003c\/p\u003e\u003cp\u003eRoClean L211 is commonly used as a maintenance cleaner for scheduled cleaning, being highly effective yet gentle enough for daily application where required. Fill the cleaning tank with RO permeate or deionized water and heat to the maximum temperature acceptable under the membrane manufacturer guidelines. Add enough L211 for a 2 percent solution by weight for moderate to severe fouling or 1 percent for mild fouling. Run through each stage individually for at least 60 minutes, with an optional soak of up to 8 hours, then flush each pressure vessel with RO permeate.\u003c\/p\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e5 Gallon Pail (45 lb) (Item RT0045-5)\u003c\/li\u003e\n\u003cli\u003e55 Gallon Drum (500 lb) (Item RT0045-55)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHigh pH alkaline cleaner: use solution pH 10.5 to 11.5 at 2 percent, 20 C\u003c\/li\u003e\n\u003cli\u003eTargets colloidal silica, clay, organic color and bioslime, plus humic and fulvic organics\u003c\/li\u003e\n\u003cli\u003eAppearance clear to amber liquid; specific gravity 1.05 to 1.2; complete water solubility\u003c\/li\u003e\n\u003cli\u003eFreeze point 14 F (below -10 C)\u003c\/li\u003e\n\u003cli\u003eLow foaming surfactant package with dispersants and chelants\u003c\/li\u003e\n\u003cli\u003eSuitable for nanofiltration and other membranes with lower cleaning pH limits\u003c\/li\u003e\n\u003cli\u003eGentle enough for scheduled or daily maintenance cleaning\u003c\/li\u003e\n\u003cli\u003eNSF certified for use as an off-line cleaner in systems producing potable water\u003c\/li\u003e\n\u003cli\u003eViton is not recommended with this product, unlike the RoClean powders\u003c\/li\u003e\n\u003cli\u003eHighly buffered to resist pH change during the cleaning cycle\u003c\/li\u003e\n\u003cli\u003eRecirculate a minimum of 60 minutes per stage; heavily fouled elements may soak up to 8 hours\u003c\/li\u003e\n\u003cli\u003eRecirculation flow per vessel: 10 gpm (2.4 m3\/hr) for 4 inch elements, 40 gpm (9.0 m3\/hr) for 8 inch elements\u003c\/li\u003e\n\u003cli\u003eCompatible with polyamide membranes from all membrane manufacturers\u003c\/li\u003e\n\u003cli\u003eMix with RO permeate or deionized water heated to the maximum temperature allowed by the membrane manufacturer\u003c\/li\u003e\n\u003cli\u003eUnopened shelf life 12 months when stored between 45 and 100 F (7 to 35 C)\u003c\/li\u003e\n\u003cli\u003eAluminum, brass, copper and mild steel are not recommended for use with this product\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eScheduled maintenance CIP on surface water RO with humic and fulvic loading\u003c\/li\u003e\n\u003cli\u003eColloidal silica and clay fouling where a liquid cleaner is preferred\u003c\/li\u003e\n\u003cli\u003eNanofiltration and membranes with restricted upper cleaning pH limits\u003c\/li\u003e\n\u003cli\u003eBioslime and organic color removal on seawater, brackish or wastewater systems\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kurita America Inc","offers":[{"title":"5 Gallon Pail (45 lb)","offer_id":52873022341431,"sku":"RT0045-5","price":732.6,"currency_code":"USD","in_stock":true},{"title":"55 Gallon Drum (500 lb)","offer_id":52873022374199,"sku":"RT0045-55","price":7387.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/RT0045-5.jpg?v=1787259939","url":"https:\/\/www.blacklabelsupply.io\/products\/avista-roclean-l211","provider":"BLACK LABEL","version":"1.0","type":"link"}
