Demineralisation is the process of removing mineral salts from water by using the ion exchange process. It comprises of minimum two vessels filled with Cation and Anion exchange resin respectively. It removes 99% of ions present in water and hence reduces TDS / EC by 99%. Demineralised water is specially purified water that has had most or all of its mineral and salt ions removed, such as Calcium, Magnesium, Sodium, Chloride, Sulphate, Nitrate and Bicarbonate. It is also known as Deionised water.
Mixed Bed Plant – Mixed Bed Plant is a single vessel unit, which contains Cation and Anion exchange resin. When it comes to require high-purity Demineralized Water, mixed bed demineralizer is considered more efficient in many ways. It is used as polishing unit to purify water to higher levels, which is treated through Two Bed demineralizer or Reverse Osmosis Unit at earlier stage.
Demineralised water is used for industrial and scientific purposes. Some of the most common uses are:
- Laboratory applications and testing
- Wash water for computer chip manufacture, and other microelectronics
- Automotive uses eg. lead-acid batteries and cooling systems
- Paint Shop
- High pressure boiler feed
- Laser cutting
- Industrial painting
- Pharmaceutical manufacturing
- Fire extinguishers
At Saara Corporation, we manufacture DM Plants and Mixed Bed Demineralizer Plant from 1 m3/h with manual or automatic regeneration facility as required.
We also undertake Annual Maintenance Contract (AMC) of DM Plant, which is not mandatory but advisable for minimizing downtime and maintaining running cost.
Demineralised water is NOT generally used for drinking water, as it is the minerals in potable water that provide the health benefits and taste. It also tends to remove minerals from food and electrolytes from the body, so it is not usually recommended for drinking or cooking.
We provide DM Plants of capacity from 500 LPH to 10,000 LPH meeting commercial as well as industrial requirements.
