Fibreglass Reinforced Plastic Vessels are the water softeners that have capacities which vary from 4. 3m3 to 420m3. The FRP Vessel has a total input hardness level of 200ppm expressed as calcium carbonate. The FRP Vessel uses the well-proven "ion exchange" process to convert the hard water ions of calcium and magnesium to sodium ions. Fibreglass Reinforced Plastic Vessels ensures that the resultant water to service is typically less than 4 ppm total hardness.
