Specialty Filtration Media

ResinTech SIR-150 is a borate selective macroporous chelating weak base anion resin. Its unique functionality provides exceedingly high selectivity for boron in almost any aqueous solution, yet can be regenerated with acid and then neutralized with various alkaline salts prior to reuse.

ResinTech SIR-200 is a mercury selective hydrogen form macroporous weakly acidic cation resin. Its unique functionality makes it selective for mercury and other heavy metals as well as for noble metals when present as cations. SIR-200 is intended for mercury removal and the removal/recovery of various precious metals.

ResinTech SIR-300-pH-Adj is a sodium form macroporous chelating weak acid cation resin. Its unique chelating functionality removes divalent transition metals preferentially to alkaline earth metals such as calcium. SIR-300-pH-Adj is intended for the removal of low to moderate concentrations of heavy metals from waste streams.

ResinTech SIR-300 is a sodium form macroporous chelating weak acid cation resin. Its unique chelating functionality removes divalent transition metals preferentially to alkaline earth metals such as calcium. Since the sodium form is highly alkaline, pH adjustment is usually required before first use.

ResinTech SIR-400 is a free base form macroporous chelating weakly basic anion resin. Its unique functionality makes it selective for mercury and other heavy metals as well as for noble metals when present as cations. SIR-400 is intended for mercury removal and removal/recovery of various precious metals.

ResinTech SIR-500 is a sodium form macroporous chelating weak acid cation resin. Its unique chelating functionality is particularly selective for alkaline earth metals such as calcium and divalent transition metals such as copper and nickel. pH adjustment is usually required before first use.

ResinTech SIR-600 is a sodium/potassium form granular naturally occurring aluminosilicate zeolite. It is an inorganic cation exchanger that can also capture certain ions by molecular sieving.

ResinTech SIR-700-HP is an acid salt form weak base gel anion resin with unique epoxy polyamine functionality. The HP designation means it is Gold Seal Certified by the WQA for use in potable water applications.

ResinTech SIR-800 is a sulfite form strong base gel anion resin. SIR-800 removes oxygen from water by converting sulfite to sulfate on the resin exchange sites. ResinTech SIR-800 is intended for oxygen removal applications and for other processes where an immobile reducing agent is needed. SIR-800 is supplied in the neutral sulfite form.

ResinTech SIR-900 is a granular aluminum oxide-based adsorbent. It has a strong adsorptive capacity for a variety of contaminants including lead, arsenate, and selenate. SIR-900 is intended for the removal of fluoride from water and can also be used for the removal of arsenate, selenate, and lead from potable water.

ResinTech SIR-950 is a specially manufactured bone char carbon. It is a granular activated carbonaceous material that has a unique combination of hydroxyapatite [Ca10(PO4)6(OH)2] and carbon.

ResinTech SIR-1300 is a chloride form hybrid gel strong base anion resin. It has crystalline manganese oxide mono-atomically dispersed throughout the polymer. The manganese oxide hybrid material stores oxygen atoms that combine with ferrous iron to form insoluble ferric oxide, which is trapped inside the resin bed. Oxygen is replenished by an air scour at the start of the cleaning cycle that also separates the suspended solids from the resin beads. Accumulated iron particles are then removed by backwash. SIR-1300 is intended for removal of ferrous iron from potable water.

ResinTech SIR-1200 is a chloride form type 1 gel strong base anion resin. It has an exceptionally high capacity and is optimized for mining and single-use applications. SIR-1200 is intended for use in uranium removal as well as the removal of other trace contaminants such as chromate and arsenate in industrial applications.

ResinTech SIR-1000 is a copper selective macroporous chelating weak base anion resin. Its unique functionality provides exceedingly high selectivity for copper as well as other transition metals in almost any aqueous solution, yet can be regenerated with acid and then neutralized with various alkaline salts prior to use.

ResinTech BSM-50 is a borate form antimony and silica selective hybrid gel type 1 strong base anion resin. Hydrated iron oxide is monoatomically dispersed throughout the polymer, giving the product hybrid properties. The borate form hybrid is able to remove chloride and sulfate in addition to silica, antimony125, and other radionuclides.

ResinTech IT-5 is an inert plastic low density granular support media for packed beds. IT-5 is significantly less dense than water and is lenticular in shape. It acts as an upper support bed and prevents resin fines from clogging distributer screens. IT-5 is intended to float above the active resin in packed bed ion exchangers.
