Kelvin’s Water Softener plants use the following methods to soften water

Traditionally, water softeners replace the minerals in hard water with sodium using a process called ion exchange. In this process, the hardness ions are exchanged for sodium ions. There are two tanks inside this type of water softener. One contains resin beads, while the other holds salt and a liquid brine. Water passes through the resin tank, and the positively charged ions in the water are drawn to the negatively charged resin beads. Ion-exchange devices reduce the hardness of the water by replacing magnesium and calcium (Mg2+ and Ca2+) with sodium or potassium ions (Na+ and K+), thus making the water soft. Kelvin Water Technologies Pvt Ltd is the right place to contact for best quality water softener plants.

Chemical precipitation is one of the common methods used to soften water. Normally used chemical for this purpose is Lime. Lime softening is the process in which lime is added to hard water to make it softer. The process is also effective at removing a variety of microorganisms and dissolved organic matter by flocculation. It has several advantages over the ion-exchange method but is mainly suited to commercial treatment applications.

We at Kelvin, at times also use chelating agents to soften the hard water. Water softener Chelators are small molecules that bind positively to any metal ions. Chelators can bind with any metal ions specially calcium and magnesium in a given solution. Such binding prevents these minerals from forming insoluble precipitates on the surface of our shower walls. Some chelators are simple molecules that can be easily manufactured (e.g., ethylene diamine tetra acetic acid; EDTA). Others are complex proteins made by living organisms. Chelators are used in chemical analysis, as water softeners, and are ingredients in many commercial products such as shampoos and food preservatives.

RO removes the contaminants and minerals in the water by using a filter. For softening water, special membranes are required in RO system which contain inbuilt pores large enough to admit water molecules to pass. Membranes are a type of water filter requiring regular cleaning or replacement maintenance. In the membrane, the hardness ions such as calcium and magnesium remain behind and they get flushed out into a drain by excess water. The result is supply of soft water which is free of hardness ions without any other ions being added.

Kelvin’s Demineralisation Plants come in following types:

As the name itself suggests, demineralized water/deionized water is almost completely free of minerals such as Magnesium, Calcium and other naturally occurring dissolved minerals. Demineralized water generally has TDS (total dissolved solids) of 0 to 10 mg/L (ppm) on the other hand, spring or mineral waters have TDS levels of between 50-300 mg/L. The term “demineralized water” sounds innocent enough, however, is it not recommended safe for drinking. As part of our Corporate Social Responsibility (CSR), Kelvin Water Technologies Pvt Ltd has summed up the findings of World Health Organization (WHO) regarding consumption of demineralized water.

World Health Organization (WHO) has cited following health effects of drinking demineralized water:


Brewing & Distilling
Food & Beverage
Metals Finishing

Water Softener & DM Plant -FAQ

Q1. What is water softening?

Ans. Water softening is a process that removes the ions that create hard water, most commonly calcium and magnesium ions. During softening, iron ions may also be eliminated. The most effective technique to soften water is to utilise a water softening device that is directly connected to the water source.

Q2. How much sodium does one absorb from softened water?

Ans. The amount of sodium absorbed through softened water is determined by the hardness of the water. Drinking softened water results in less than 3% salt intake on average. According to various estimates, a person consumes two to three tablespoons of salt every day. Considering a daily sodium intake of five grammes and a water consumption of three quarts, the contribution of sodium (Na+) in the water from the home water softening process is negligible in comparison to the entire daily intake of numerous sodium-rich foods.

Q3. What is DM plant?

Ans. Demineralisation is the removal of mineral salts from water via the ion exchange process. Demineralisation can be used with most natural water sources to create water of greater quality than standard distillation.

Q4. What is the difference b/w RO and DM Plant?

Ans. RO water is produced by passing raw feed water through a membrane/s that removes ionic and several non-ionic (organic and suspended) compounds. RO water is produced by using high pressure to force water molecules through an osmotic membrane, resulting in an ion-rich stream on the feed side of the membrane and a purer from ion stream on the product side of the membrane. DM water is produced by running raw water through demineralization beds (typically two. one designed to remove positively charged ions. cations. followed by a second bed designed to remove DM water is produced by running raw water through demineralization beds (typically two. one designed to remove positively charged ions. cations. followed by a second bed designed to remove negatively charged ions. anions. It will have less "ion slippage" than RO systems, resulting in higher quality water.

Q5. How does a DM plant work?

Ans. In two-bed demineralization, a stream is first treated with a strong acid cation (SAC) resin, which captures dissolved cations and releases hydrogen (H+) ions in return. The mineral acid solution is then sent to the resin bed for strong base anion extraction (SBA).

Q6. What is the advantage of DM plant?

Ans. Advantages of DM Plant Are-

  • The water produced by these devices is far superior to the distilled water we normally use.
  • You will be able to select among DM plants of various sixes and specs. Units will be created and built for use in laboratories, as well as units for big, medium, and small-scale companies.
  • There are no chemicals used in the purification process. Also, no hazardous waste products are generated during the process.
  • Most new systems will not require much storage space.
  • It has been discovered that using DM plants to demineralise water reduces total product cost in industrial manufacturing facilities.
