Reverse Osmosis and Other Treatments Water Purifiers Use

Water is treated in a variety of ways. The most widely used method is reverse osmosis, (also known as RO treatment) although other methods do exist. Treatment of water is done to eliminate pollutants and contaminants from it. Other methods used commonly by water purifiers are ozone treatment, membrane technology and ultraviolet treatment.

You need to drink only purified water no matter where you live, whether in Kolkata or a suburb or a rural area.

What is RO Treatment?

Reverse osmosis a very effective water treatment method. Commonly used in home water purification, it involves forcing water through a membrane that traps the impurities. It uses pressure to force the water and the membrane through which the water is forced is highly dense so that impurities cannot get past it.

The process does not impact the taste of the water, also, the smell of the water (if any), remains intact. ro water purifiers in kolkata that use this method, remove toxins and microbes. However, it has a downside – the minerals are also removed in the process of RO filtering. Furthermore, the membrane needs cleaning and replacement from time to time as it traps all sorts of water impurities.

What is Ultraviolet Treatment?

It is a method where water is passed through germicidal UV light that has been fit inside a low pressure lamp. When passing through, the water’s impurities come into contact with UV light and are destroyed immediately. Though it is effective in killing contaminants, it fails to free the water of dissolved chemicals and the like. Ultraviolet treatment is used mostly in hotels, laboratories, hospitals, dairies and many other commercial premises 

What is Membrane Treatment?

In this method, impurities in the water are removed using a semi-permeable membrane. This membrane could either be operated by electricity or by hydraulic pressure like the reverse osmosis method. It eliminates all sorts of biological and organic contaminants from the water but is expensive.

What is Ozone Treatment?

Ozone gas is used for exterminating biological contaminants that live in water. The gas also eradicates all kinds of odor and pollutants like sulfur, iron, manganese etc. from the water. There are 2 disadvantages of this method – 1: it leads to the creation of some mild carcinogenic byproducts and 2: it is expensive

Different water purifiers in kolkata use different methods to give you clean and safe drinking water. People living in Kolkata can find water filters at cheap rates.
