Working of a Water Purifier

In Water Purifiers, water passes through a deposit filter. The deposit filter removes all particulate and solid impurities and then passes through a fine filter particularly to remove iron, chlorine and other minerals. There are many different types of water purifiers on the market today that function based on several technologies.


  1. RO Water Purifier

RO water purifiers require electricity and speedy water. In RO water purifiers a semipermeable membrane is used to purify water. Firstly the water passes through this membrane by which salt, lead, chlorine, fluorides and all other dissolved solids get stuck in the RO membrane. Resulting in improved taste and odor or the water. These are especially capable to purify hard water contains dissolved solids. Such purifiers are cost effective and quite easy to maintain.

UV water purifiers are capable to kill bacteria, viruses that cause water borne diseases but cannot purify hard water. These are not as efficient as RO purifiers to purify hard water. Such purifiers are easy to maintain, cost effective and use low amount of energy.

All these particles gets trapped in the membrane, pure water is separated easily. The technology used in RO is very similar to the one used in this one, the only major difference is that RO purifiers can block very small particles also. Like UV purifiers, these are also not capable of working with hard water. The main advantage with these types of purifiers is that these work without electricity.

  1. Activated Carbon Water Purifier

Activated carbon removes heavy metals and pesticides that cause most of the water borne diseases. It helps in removing chemicals that are a cause of bad smell and taste of the water. These purifiers use absorption property to make water uncontaminated. These purifiers are very useful in removing all chemicals and metal particles but do not remove salt.
