{"product_id":"purolite-gelular-tannin-res","title":"Purolite Gelular Tannin Res","description":"\u003cp\u003ePurolite A850 is a gelular Type I strong base anion exchange resin built on an acrylic matrix, formulated to adsorb the soluble tannins that give drinking water unwanted color and taste. Supplied in a 1\/2 cubic foot box, it is a targeted solution for surface and well waters affected by organic staining and off-flavors that come from decaying vegetation and natural organic matter.\u003c\/p\u003e\u003ch3\u003eHow it works\u003c\/h3\u003e\u003cp\u003eThe acrylic matrix is the key to this resin's performance: it excels at removing organic matter and, crucially, releases those organics again during regeneration. That reversible loading helps protect the bed from permanent organic fouling, a common failure mode for anion resins exposed to tannin-laden water. A850 also regenerates very efficiently, requiring lower levels of sodium hydroxide than a comparable polystyrene-based Type I resin, which translates into lower chemical use over the resin's life.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Purolite (A850)\u003c\/li\u003e\n\u003cli\u003eGelular Type I strong base anion resin, acrylic matrix\u003c\/li\u003e\n\u003cli\u003eTargets soluble tannins causing color and taste issues\u003c\/li\u003e\n\u003cli\u003eReversible organic removal for strong fouling resistance\u003c\/li\u003e\n\u003cli\u003eEfficient caustic regeneration versus polystyrene Type I resins\u003c\/li\u003e\n\u003cli\u003eVolume: 0.5 CF box; weight approximately 28.4 lbs each\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eDespite its tannin focus, A850 retains a strong ability to remove weaker acids including carbonic acid and silica, comparable to standard Type I resins, which broadens its usefulness in demineralization-style applications. It is often deployed alongside a polystyrene-based resin, such as in a mixed bed positioned after an anion unit, where the combination removes a wider spectrum of organic compounds than either resin could achieve alone.\u003c\/p\u003e\u003cp\u003eFor water-treatment professionals tackling tannin color, taste, and general organic contamination, this Purolite gelular resin offers an efficient, fouling-resistant option that holds up well in challenging waters. Routine regeneration with caustic restores its adsorption capacity and keeps treated water clear and clean-tasting cycle after cycle. Correct bed sizing and contact time ensure the resin captures tannins effectively before breakthrough, making A850 a reliable choice for organics removal.\u003c\/p\u003e\u003cp\u003eWhen designing a tannin system, pairing A850 with adequate contact time and a regular regeneration routine ensures the resin keeps pace with seasonal swings in organic loading, which can vary considerably in surface-fed supplies. For homeowners and installers battling tea-colored water and musty tastes, this Purolite gelular resin offers an efficient, fouling-resistant path to clear, pleasant drinking water.\u003c\/p\u003e","brand":"Nelsen Corporation","offers":[{"title":"Default Title","offer_id":45668713988149,"sku":"A850-50-BOX","price":475.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/purolite_logo_9a68959f-27bf-4faf-b157-8d9dea390228.jpg?v=1782677939","url":"https:\/\/watersoftenerplus.com\/pl-eu\/products\/purolite-gelular-tannin-res","provider":"Water Softener Plus","version":"1.0","type":"link"}
