Membranes, Resins & Materials for water desalination, water purification and separation processes
Application Uses

Ultrapure water (resistivity: 18.2 MΩ cm; pH: 7.0) and 10-50 litre per hour using indigenously developed ion-exchange membranes for electronics, pharmaceuticals and other niche applications

Salient Technical Features
  1. All components such as ion-exchange membranes, resins, electrodes are indigenously available.
  2. Continuous regeneration of mixed bed resin
  3. Steady quality control for the product water (resistivity: 18.2 MΩ at 25 oC; TOC: 1 ppb; pH: 7.00 flow rate: 15 LPH).
  4. Ground water or municipal water may be taken as feed water
  5. High percentage of water recovery
  6. Maintenance cost: Negligible
