Demineralization Plan (DM Plant)

We are Manufacturer, Supplier, Exporter of Demineralization ( DM ) Water Treatment Plants and Our setup is situated in Pune, Maharashtra, India.

We provide our entire range across ALL OVER INDIA .

Demineralization (DM) is the process of removing minerals, salts ( such as cations - sodium, calcium, iron, copper, and anions such as chloride, sulphate, nitrate, etc) from Water by using one of the following processes :

  • Ion Exchange ( Cation- Anion- Mixed Bed) Treatment
  • Membrane Filtration (Like Reverse Osmosis followed by MB )
  • Electro DeIonisation (EDI)- RO+ EDI
  • Distillation / Evaporation
About The Sigma Watertech Corporation

Ion Exchange: Demineralised (DM) Water known for typical conductivity < 30 umhos/cm. Deionised (DI) Water is known as more purified DM water with the help of a Mixed Bed (MB )unit or Electro De-Ionisation (EDI). MB-based DI water produces Conductivity < 5 umhos/cm. EDI-based DI water produces Conductivity < 0.5 umhos/cm.

Raw Water Pretreatment

Most of the time its desired that raw water be treated for the removal of the suspended solids (TSS) with the help of a Pressure Sand Filter (PSF) and to be treated for removal of Colour, Odour and Organic matter with the help of Activated Charcoal Filter (ACF). These units shall help in enhancing the life of the resins/ membrane and to offer the desired water quality.

The membrane-based systems like RO+MB is becoming more popular because of automation in the membrane system and less manpower requirement for the regeneration process.

  • Distillation: is nowadays outdated technology due to electrical power consumption.
  • Evaporation: such as MEE is being used in the recycling of wastewater

    • Principles

    Majorly 2 principles were used for producing DM/DI quality water:

  • Ion Exchange adsorption - The cations and anions present in water are replaced with the active resin parts and then recharged by using acid and alkali.
  • Membrane separation - Reverse Osmosis followed by MB - The Total dissolved solids get separated with a semipermeable membrane leaving behind very low salt at permeate (product) side.
