Water Softener Plant

Hardness is a chemical parameter of water that represents the total concentration of calcium and magnesium ions. It is called hardness because if calcium and magnesium are present in your water, making a lather or suds for washing is "hard" to do.

Term	Grains/gallon	mg/L or ppm
Soft	Less than 1.0	less than 17.1
Slightly Hard	1.0 to 3.5	17.1 to 60
Moderately Hard	3.5 to 7.0	60 to 120
Hard	7.0 to 10.5	120 to 180
Very Hard	10.5 and above	180 and above

The softener plant degining capacity 100 to 2,00,000 Ltr. Per Day depend on water property with water your requirement.

Water Hardness exist in significant areas of the country that result in disappointing white scales on fixtures, appliances and piping. Softening of water produces immediate benefits such as reduced usage of soap and detergent, cleaner clothes and better taste of food and beverages

Prevent Scaling in boilers, geysers, heat exchangers, press, etc.
Prevent Scaling & corrosion in pipelines and bathroom fittings.
Save up to 70% of detergent & soap in washing process.
Prevent scaling on human skin & stop hair loss.
Reduces cooking time and consumption of gas.
Reduces electricity bill.
Low maintenance cost.

DM Plant

The plant degining capacity 100 to 2,00,000 Ltr. Per Day depend on water property with water your requirement.
The demineralisation process utilizes acid regenerated action resin & caustic regenerated anion resin to remove minerals from water. We offer DM Plants of different sizes as per requirement of the customers. Trolley mounted automatic operation DM Plants are also available for small industries and laboratories

Demineralization or Deionisation is the process of removing mineral salts from water by using the ion exchange process. With most natural water sources it is possible to use Demineralisation and produce water of a higher quality than conventional distillation.
unistar aquatech Manufacture a Wide range of custom-built softening, Dematerializing plants for industrial process water applications, with inherent design to conserve water, and save costs. They are available in different sizes and materials, manually operated or fully Automatic, & ready to install & are available as standard models or custom built versions for specific needs.

Operating Principle

A Typical two-bed DM Plant consists of two FRP/MS Rubber lined Pressure vessels connected in series along with its internal fittings. The first unit consists of high capacity strongly acidic cation exchange resin, which converts positive ions of salt and replaces them with hydrogen ions to form respective acids, which are absorbed in next vessel by strongly basic anion exchange resin. The water obtained by this process shows conductivity less than 20 µ S / cm at 25o C and total dissolved solids less than 10 ppm.
Further high purity water can be achieved by Mixed Bed Deionisers, which are designed to produce high purity treated water. They can be used as polishing units after two bed DM Plant to obtain high purity water. Mixed Bed Deionisers are single column units, filled with strongly acidic cation and strongly basic anion exchange resins mixed together.

There are four distinct stages in the operation of Deionisers
• Service
• Backwashing
• Regeneration
• Rinse/remix

Service

In the Service cycle the water enters the vessel and passes through the Resin bed of the respective exchanger

Backwashing

After the resins are exhausted, the bed is backwashed. Backwashing is carried out by a uniform upward flow of water through the resin bed. The backwash step expands the resin bed releasing any entrapped particulate matter & removes the channeling in the resin column if occurred during the service cycle.

Regeneration

When the ion exchange resins loose all the exchangeable ions, they require regeneration to restore them back to hydrogen or hydroxyl form depending upon whether they are cation or anion resins. To achieve this 4 - 5% concentrated solution of Hydrochloric acid is used for cation resin and a 4% - 5% concentrated solution of caustic soda for anion resin. Sulphuric acid can also be used for Cation Regeneration but the concentration of acid during injection must be kept at minimum, such as to prevent calcium sulphate precipitation on the resin.
