Water pollution is a main concern over the last century; it is being increasing day by day. Most of the water resources in our earth are loaded by waste dumped by humans. So the need for water purification has become a must to ensure that you are drinking safe and pure water. Buying a water purifier is the best way if you are concerned about the TDS level and hardness of water you are drinking. There are so many water purifiers are available in the market with varying technology. It’s important to know about which water purifying technology will suit for your drinking water.
Water Purifying Technologies
Reverse Osmosis (RO) is a process in which dissolved inorganic solids such as Fluoride, Detergents, Pesticides, etc. are removed from water. This is accomplished by household water pressure pushing the tap water through a semi permeable membrane. The impurities are filtered out and subsequently flushed down the drain. RO units incorporate a 4-5 stage process for optimal water quality.
Ultraviolet (UV) water purification is used for disinfecting bacteria from the water. It is the most effective way to penetrate harmful pathogens in your home’s water and destroy illness-causing microorganisms by attacking their DNA.
Note: Microfiltration (MF) – Technically MF uses the same process as UF. But UF membrane pores are smaller than MF membrane pores. MF pore diameters have a range of 0.01 μm to 10 μm.
Ultrafiltration (UF) is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semi permeable membrane with bigger pores than RO. It will work without electricity and completely remove all microorganisms from water including the smallest of viruses.
Gravity based water purifiers do not use electricity instead of that; it uses activated carbon or UF for water purification. 150 ppm is the ideal TDS level for gravity water purifiers.
Programmed Germkill Technology is a purification technique used by Pureit purification system. Its Germkill Battery Kit consists of the Compact carbon trap, Germkill processor, and Polisher. It doesn’t use electricity and chemicals for the purification.
