The HP designation means the resin is \u003cstrong\u003eWQA Gold Seal certified for potable water\u003c\/strong\u003e, so the media itself has been third-party verified safe for drinking water service. It removes \u003cstrong\u003enitrate and nitrite\u003c\/strong\u003e, and also has strong affinity for \u003cstrong\u003eperchlorate\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThis is the \u003cstrong\u003eexact media inside our whole-house nitrate systems\u003c\/strong\u003e: the \u003ca href=\"\/products\/nitrate-filter-system-6-gpm\"\u003e6 GPM system\u003c\/a\u003e (1.5 cu ft), the \u003ca href=\"\/products\/nitrate-filter-system-10-gpm\"\u003e10 GPM system\u003c\/a\u003e (2.5 cu ft), and the \u003ca href=\"\/products\/nitrate-filter-fleck-5600sxt-1-5-cubic-foot-10-54-vortech\"\u003eFleck 5600SXT nitrate filter\u003c\/a\u003e (1.5 cu ft). The 1 cubic foot bag is for owners rebedding one of those tanks, and for DIY builders loading a custom nitrate system who want certified, nitrate-selective resin rather than generic bulk media.

Once those beds load up with sulfate, they can \u003cstrong\u003edump previously captured nitrate back into your water\u003c\/strong\u003e, sometimes above source levels, with no warning. SIR-100-HP's amine functional group is engineered to prefer nitrate: \u003cstrong\u003eno nitrate dumping, even past the sulfate break\u003c\/strong\u003e, plus higher operating capacity and lower leakage than conventional anion resin. High sulfate still reduces working capacity, so confirm sizing on high-sulfate wells by phone with your water test.\u003c\/p\u003e\n\n\u003ch3\u003eRegenerable With Ordinary Softener Salt\u003c\/h3\u003e\n\n\u003cp\u003eUnlike single-use media, SIR-100-HP \u003cstrong\u003eregenerates with a sodium chloride brine\u003c\/strong\u003e: ordinary water softener salt at a dose greater than 10 lbs per cubic foot, with at least 30 minutes of brine contact. Each regeneration flushes the captured nitrate to the drain and restores the bed, cycle after cycle, for years. On hard water, use \u003cstrong\u003esoftened or low-hardness water for brine makeup\u003c\/strong\u003e to avoid calcium carbonate scaling in the brine system.\u003c\/p\u003e\n\n\u003ch3\u003eSizing and Loading\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10\" x 54\" tank holds 1.5 cu ft\u003c\/strong\u003e - 2 bags (our 6 GPM system and the Fleck 5600SXT nitrate filter).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e13\" x 54\" tank holds 2.5 cu ft\u003c\/strong\u003e - 3 bags (our 10 GPM system).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum bed depth 24 inches\u003c\/strong\u003e - shallower beds short-circuit and leak early.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService flow 1-4 gpm per cubic foot\u003c\/strong\u003e - slower flow means more contact time and better capture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating range\u003c\/strong\u003e - pH 4-10, max continuous temperature 170 F, total capacity 1.0 meq\/mL, backwash expansion 25-50%, ship weight ~41 lbs per cubic foot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-treatment required\u003c\/strong\u003e - sediment, iron, and hardness must be handled upstream or they foul the bed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTest First, Then Size\u003c\/h3\u003e\n\n\u003cp\u003eNitrate is colorless, odorless, and tasteless, so both the initial sizing and the annual performance check come from a lab test.
