De Mineralization System


Demineralization is a type of water purification. It can refer to any treatment process that removes minerals from water. The term demineralization is typically reserved specifically for ion exchange (IX) processes used for near total removal of ionic mineral contaminants. H2OMSPL’s De Mineralization system removes dissolved salts from the water. TDS < 10 PPM is achieved at the outlet of the system. De mineralization system consists of two segments, i.e. Strong Acid Cation (SAC) and Strong Base Anion (SBA). HCl is used to regenerate SAC and NaOH is used to regenerate SBA after exhaustion of OBR. This filtration system is extensively used for industrial and pharmaceutical applications. De-Mineralization system can be used standalone but it is better to provide multi grade sand filter and activated carbon filter as pretreatment to avoid fouling of resin.

Specifications :

  • One Set of Internal Collection and Distribution System
  • One initial charge of Resin for SAC and SBA as per process requirement
  • One Set of Frontal Pipework and valves as per system design
  • DM Plant (Cation + Anion) with Vessel MOC as FRP and operated through Manual/Auto Multiport Valve
  • Two nos. of pressure gauges to calculate pressure drop across each vessel
  • Operating pressure of 2.5 to 3.5 bar
  • One Nos. of each Acid Measuring Tank and Caustic Dilution Tank
  • One Nos. of Conductivity Indicator
  • H2O MSPL provides De Mineralization Plants in various size’s depending on feed water condition and capacity.

Salient Features :

  • Effective for reducing TDS
  • Low maintenance costs
  • Easy to operate
  • Less wastage of water
  • Feed water can be used for regenerating/ rinsing the De Mineralization System

Applications :

  • The De Mineralization system has vast applications due to its effectiveness and low maintenance costs
  • The De Mineralization system has Industrial and Pharmaceutical applications
  • H2O MSPL provides a Water Softening system in various sizes and metallurgy (FRP, MS-EP, MS-FRP, MS-RL, SS 304, SS 304L, SS 316) as per client and process needs
  • We do not recommend drinking of De Mineralized water


  1. Depends on feed water quality
  2. Dosing of suitable coagulant will provide more effective filtration
