• Water is considered ‘hard’ when it has excessive levels of calcium and magnesium dissolved in it. Water softening plant is used for removal of total hardness dissolved in Water. We, at NK offer Series of water softeners at a low cost, reliable and highly efficient way to soften your water.
• Our unique design of Water softening plant ensures the maximum utilization of the effective surface area, uniform space and linear velocity across the resin bed which provides effective contact time between water and resin bed yield, soft water and prevent any precipitation and scale formation on the surface of heat exchanges and any process equipment where water is being used for further application.
  NK water softeners are available in diameters from 0.225 mts. to 4.0 Mts. with the flow rates up to 250 m³/hr. and OBR up to 2200 m³@400 PPM hardness. These strong, pre-engineered, pre-assembled units minimize installation and start-up costs. Our Water Softener Plant is acclaimed in the market for cost efficiency and consistent functioning.

Working Principle:

• Softening is a process where Calcium and Magnesium ions are exchanged for Sodium ions. Calcium and Magnesium ions associated with Alkalinity contribute for scale formation. These ions are also called as Total hardness. The strong acid Cation exchange resin in Sodium form is used for softening the water. When the resin is exhausted, it is regenerated with brine (Sodium Chloride solution) 10 % or 15% brine is normally used for the regeneration. If service flow is from the top to bottom, then it is called as down flow softener. If the service flow is from bottom to top, then it is called as up flow softener. The softeners are run up to the Hardness slip of 5 ppm as CaCO3 in the treated water, which is called as Industrial Zero hardness.
