Reverse Osmosis Water Filtration Systems
If you are looking for a purifier that can remove all the impurities from your water then you should opt for a reverse osmosis water purification system as it has ability to do the same. It is also famous among various bottling companies.
A reverse osmosis water filter can stop very minute particles to pass through it. The size of membrane pores in a RO system is approximately 0.0005 micron which is much smaller than the size of bacteria, virus or any other particle.
RO membranes are of two types: Thin Film Composite (TFC) and Cellulose Triacetate (CTA). TFC membranes eliminate more impurities than a CTA membrane. However, TFC membranes are more likely to be corrupted by chlorine. For this reason, carbon pre-filters are used in RO filters.
A RO system includes granular activated carbon (GAC) pre-filters, reverse osmosis membrane, storage tank and a faucet for delivering purified water. The quality of a RO system depends on the quality of membrane used and storing capacity of the tank.
Semi permeable membrane used in a reverse osmosis system allows pure water to go and does not allow impurities to go through it. Pressure is used in RO system to disinfect the water and strong pumps are used to solve this purpose.
The membrane that is used to filter out the impurities is cleaned by a process called cross flow. In this process the filtered impurities are removed along with waste water by means of a drain. As the impurity is flushed away the membrane remains clear and dust free.
If a membrane will continuously clean the chlorine, iron, manganese, hydrogen sulfide and bacteria it will soon be damaged. Therefore, sediment pre-filter and an activated carbon pre-filter or post-filter are used along with membrane to enhance the durability of the filter. This system is very effective in removing nitrate from water.
No doubt, RO system is an unbeatable choice for every individual and is preferred over any other purification system, but it is not fit for cleaning water that contains a lot of biological dust like untreated lake water. For cleaning such water it needs to have an ultraviolet system along with it.
