Water Softeners - A brief look

What is hard water?

Hard water is basically a high concentration of minerals in the water, most commonly dissolved compounds of calcium and magnesium, either as carbonates or sulphates. Water hardness is measured by how many parts per million (ppm) of the minerals are dissolved in the water.

What are the causes of hard water?

Hard water can be either temporary or permanent.

Temporary hardness in water is often caused by the presence of dissolved carbonate minerals (calcium carbonate and magnesium carbonate). Boiling hard water precipitates the calcium carbonate out of solution, leaving water that is softer when it cools. However, suspended particle remain unaffected even after boiling.

Permanent hardness is usually caused by the presence of calcium and magnesium sulphates in the water. These salts become more soluble as the temperature increases, and cannot be eliminated by boiling. Despite the name, permanent hardness can be removed.

Both kinds of hardness, temporary and permanent, can be removed by installing a water softener, which filters out most of the minerals suspended in the water.

What are the effects of hard water?

Below mentioned are some effects of hard water.

On Clothes:

Hard water prevents formation of adequate lather, which leads to higher soap consumption. What's more, clothes become stiff, rough and remain dirty even after washing.

While Bathing:

Bathing with hard water makes hair sticky and leads to hair loss as well. Also the skin feels dry and itchy after bathing.

On Dishes:

Using hard water while cleaning, leads to the formation of chalky white spots on utensils and cutlery. This further reduces their life span.

Hard water can also clog your pipes and prevent your washing machine from operating at full efficiency.

In commercial applications, hard water can present a real problem. Hard water deposits (off-white scales) can clog pipes. It can be deposited on the surfaces of pipes and heat exchangers, restricting the flow of water, and compromising the efficiency of the heat exchanger. In some cases, it even causes corrosion. Mineral deposits can also cause metal boiler components to
overheat, and can cause the boiler to fail.

Installing and maintaining a water softener, as part of industrial water treatment strategies will usually alleviate the problem.

Kent Mini Water Softener is the world's first compact water softener that converts hard water into soft water in an easy and convenient manner. It can be easily fitted to your washing machine, geyser and dishwasher. Kent is known as ‘House of Purity’ due to its immense contribution in the field of water purification.
