It is applied to break up and disperse biofouling and particulates, resulting in decreased differential and feed pressure. It contains a blend of proprietary buffers that dissolve organic foulants and disperse colloidal particles.\u003c\/p\u003e\u003cp\u003eFill the cleaning tank with RO permeate or deionized water and heat to the maximum temperature acceptable under the membrane manufacturer guidelines, which sharply increases cleaning efficiency. Add enough P111 for a 2 percent solution by weight for moderate to severe fouling, or 1 percent for mild fouling, and recirculate to mix. Run the solution through each stage individually for at least 60 minutes, with an optional soak of up to 8 hours on heavily fouled elements. Monitor pH throughout and rinse each pressure vessel with RO permeate before returning to service.\u003c\/p\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e45 lb Pail (Item RT0041-45)\u003c\/li\u003e\n\u003cli\u003e350 lb Drum (Item RT0041-350)\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 severe organic fouling including polysaccharides, severe colloidal fouling and moderate humic and fulvic fouling\u003c\/li\u003e\n\u003cli\u003eAppearance white powder with complete water solubility\u003c\/li\u003e\n\u003cli\u003eCleaning concentration 2 percent by weight for moderate to severe fouling, 1 percent for mild\u003c\/li\u003e\n\u003cli\u003eNSF certified under NSF\/ANSI Standard 60 for off-line use in drinking water systems\u003c\/li\u003e\n\u003cli\u003eSuitable for use alongside other Avista cleaners\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\u003eSevere biofouling and polysaccharide slime driving up differential pressure\u003c\/li\u003e\n\u003cli\u003eSevere colloidal fouling on seawater, brackish or wastewater RO\u003c\/li\u003e\n\u003cli\u003eModerate humic and fulvic (surface water) organic fouling\u003c\/li\u003e\n\u003cli\u003eDrinking water RO plants needing an NSF\/ANSI 60 certified off-line cleaner\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kurita America Inc","offers":[{"title":"45 lb Pail","offer_id":52873020965175,"sku":"RT0041-45","price":952.2,"currency_code":"USD","in_stock":true},{"title":"350 lb Drum","offer_id":52873020997943,"sku":"RT0041-350","price":4642.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/RT0041-45.jpg?v=1787259866","url":"https:\/\/www.blacklabelsupply.io\/products\/avista-roclean-p111","provider":"BLACK LABEL","version":"1.0","type":"link"}
