Water Treatment Grades define the quality and purity levels of chemicals and materials used in water treatment processes. These grades help ensure that each product is suitable for its intended application—whether in industrial systems, municipal water treatment, or drinking water purification. Selecting the correct grade is essential for safety, regulatory compliance, and treatment effectiveness.

Indion Cation Resin

Indion Cation Resin is a synthetic ion exchange resin designed primarily for the removal of positively charged ions (cations) from water and various liquid streams. Typically composed of a sulfonated polystyrene-divinylbenzene (PS-DVB) copolymer, this resin features a highly porous bead structure with functional groups that exchange hydrogen or sodium ions for calcium, magnesium, iron, and other metallic cations. Available in different forms (strong acid cation, weak acid cation), Indion Cation Resin is widely used in water treatment, industrial processes, and purification systems.
