Water Purifier & Ro: Technical Comparison

These days, people in huge number and of all ages are falling sick because of drinking contaminated water that comes out from taps, tube wells, wells and other sources. The root cause of majority of the diseases to strike is due to contaminated and germ infested water. Health and safety of the entire family has become the major factor for every household, prompting them to consider installing a water purifier.

Significance of purifiers

Safe, pure and clean water was available for thousands of years for free from nature. But with chemicals being released by the industries all over the world into water, clean drinking water, free from germs, impurities and harmful contaminants are becoming scare. This has only prompted people to look for alternative sources of drinking water. Manufacturers have realized the growing need for good, clean water and have come out with various types of devices that promise to filter water and provide only pure, clean water.

However, with advancement in technology, there have emerged different types of water filters and ROs that are easily available in the market. Moreover, they are also available in different price range to suit all needs and budget constraints. Continuous R&D is still going on at the research labs to bring forth much better devices to purify water. It is to ensure that this cleaned water has all essential minerals and good bacteria in it that is necessary for the human body to function properly and stay healthy.

But determining which one to buy can be really confusing for the first time buyers! Having knowledge of the details of the different types can help to know which can be the most appropriate one for the home or office.

Technical comparison

  • Reverse Osmosis or RO Water purifier tends to use membrane to eliminate impurities present in water like dissolved salts, metal traces, chemicals and leads from hard or contaminated water. Normal purifiers on the other hand make use of UV technology to kill microbes and bacteria. Also, chemical is not released for cleaning purpose and hence, purified water is safe and clean to consume.
  • RO purifiers move water molecules to lower solute concentration region from higher solute concentrate region. Incoming water pressure is used by reverse osmosis process to push across the membrane, thereby leaving impurities behind like dissolved impurities. Remaining water and solids are discharged from other outlets. On the other hand, normal purifiers use osmosis process, where water molecules tend to flow to higher solute concentration region to lower ones. Semi-permeable membrane found above has large holes or haps to enable water to pass through. However, they are excessively small to pass solid molecules. Solute reference in reverse osmosis and osmosis is for salts and dissolved minerals like calcium and magnesium present in water.

The fact is that different purifier types available come with their own benefits and disadvantages. Going through the technical specifications can given an idea what needs to be avoided and purchased to suit specific requirements.
