Organic Scavenger Ion Exchange Resin

Description

Organic Scavenger Ion Exchange Resin is a specially designed macroporous polystyrene–divinylbenzene resin with functional groups optimized for the adsorption and removal of natural organic matter (NOM), color bodies, tannins, humic substances, and organic contaminants from water streams. Unlike conventional anion or cation resins, organic scavenger resins have a high affinity for hydrophobic and high-molecular-weight organics, making them especially effective in protecting downstream ion exchange systems, membranes, and polishing resins from fouling. They are widely used as pretreatment in water purification and industrial processes requiring stable, long-term operation.

Applications

• Removal of tannins, humic acids, and organic color bodies from surface waters

• Pretreatment to protect mixed-bed or deionization systems from fouling

• Industrial wastewater treatment for organic contaminant removal

• Food and beverage water purification (color/taste/odor control)

• Power plant condensate polishing systems (organic control)

• Municipal drinking water systems treating high-organic surface sources

Key Features

• Macroporous resin with high surface area and porosity

• High selectivity for organic compounds over inorganic ions

• Protects downstream resins and membranes from organic fouling

• Long service life and excellent regeneration capability

• Effective across a wide pH range and in various feedwater qualities
