Ultra-pure Water System

Rotek offers a diverse range of Ultra Pure Water (UPW) modules utilizing ion exchange resins, including water softeners, deionizers (Mixed Bed Polisher), and electro-deionization systems.

Ion exchange stands as a pivotal water treatment method employed to eliminate ions from water, ensuring purification. 
It uses a resin or similar medium charged with ions to attract and exchange ions present in water. Specific ions are removed while others are added, resulting in purified water. Moreover, it softens water by eliminating calcium and magnesium ions responsible for hardness.

Water Softener


Capacity: 1,000 - 25,000 LPH


A water softener reduces the calcium and magnesium ion concentration in hard water which causes hard-scale build-up. It also inhibits the cleaning effect of detergent formulations.

Mixed Bed Polisher


Capacity: 25 - 7,500 LPH


Rotek mixed bed polisher is designed to treat RO permeate water, in order to deliver higher purity water for commercial and industrial applications, such as rinse water for electronics.

Electrodeionization (EDI) System


Capacity: 100 - 7,000 LPH


EDI system is superior to a conventional mixed-bed deionization system both in ease of operation and maintenance. In addition, no chemicals are used for regeneration during the purification process.
