Common types of water purifiers that you can find

A number of things are there which you should know prior to buying a water purifier such as zero b water purifier. The type of water purifier that you should buy will depend on the contaminants, metal particles present in the water as well as hardness of water. Water purifiers can range from just a simple water filter with filter cartridge constituent to the more advanced water purifiers using membranes for water filtration followed by sterilization with UV filter. Mentioned below are some of the most common types of water purifiers that you can find in the market. Based on the methods of water purification, water purifiers can be classified into five types such as:

  • Ultraviolet or UV
  • Reverse Osmosis or RO
  • Activated Carbon
  • Ultrafiltration or UF
  • Sediment Filter

Ultraviolet or UV

Ultraviolet water purifier is capable of killing water borne disease causing pathogens, microorganisms such as viruses, cysts and bacteria. UV water purifier comprises of a UV lamp tube through which water has to pass for purification. Once the running water is exposed to UV light from UV lamp, the germs like bacteria and viruses get inactive and damaged. The dead bodies of the germs continue to remain in water, but these are not injurious any more. In addition, UV water purifier cannot also remove chemicals such as fluoride, arsenic, chlorine present in water.

Reverse Osmosis or RO

RO water purifier uses semi permeable membrane to decontaminate water. During this process dissolved solid such as fluoride, arsenic, chlorine, lead, sulfates and nitrates are trapped, trapped in RO membrane and as a result one can get totally purified water. This type of water purifier is most efficient to purify salt and hard water. The best thing about RO water purifier is that it improves the odor and taste of water by eliminating the contaminants that cause bad taste and odor. Apart from this, RO water purifier is easy to maintain and cost effective.

UF (Ultrafiltration) Water Purifier

This type of water purifier uses void fibers of a membrane which is made using thin layer of material that is able to separate water and other particles present within water. When water passes through the UF membrane, the suspended solids, viruses as well as bacteria get trapped in UF membrane.

Sediment filter

Most of the sediment filters are made using polyester fibers and cotton. Sediment filter are available in a roll shape and it usually stays in the plastic sealed housing container. When water is passed through the sediment filter the dust and dirt particles get trapped in it and thus one can get purified water. The sediment filter cannot remove heavy metals, dissolved solids and germs such as bacteria, viruses.

Activated Carbon Water Purifier

Another form of water purifier which is available in the market is activated carbon water purifier. The activated carbon is usually made from charcoal. Activated Carbon helps in eliminating water borne disease causing heavy metals and pesticides. In addition, it can also help to remove chemicals that make water smell and tastes bad. Activated Carbon is most effectual when it comes to remove chlorine from water.

Conclusion

Choosing a water purifier for the home thus depends on the quality of water you get. As discussed above there are various types of water purification technologies and choosing which type of water purifier is best for the type of water or impurities that are present in water.
