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:
