Water Fillers Technologies

The need for clean water has always been with humans. The outbreaks of cholera, dysentery or typhoid in crowded European cities during the industrial revolution further catapulted water purification. In previous times, mechanical removal of impurities was employed. However, in present times a blend of mechanical, chemical, biological means such as ion exchange, reverse osmosis and ultra violet light. For this reason a water filter is undeniably, a necessity rather than a luxury at home. This in part is due to the high premium attached to health care, in case of sickness.

It is important however to examine the various types of filters available in the market. Most have a blend of different technologies while some just use one. The choice is however determined by the type of contaminant one seeks to get rid of. Filter technologies vary from using carbon fibre which absorbs impurities giving a contamination free filtrate. Some carbon is activated, and can remove other chemically toxic contaminants like asbestos. Volatile organic compounds, Lead, mercury, have been proven to be easily removed by these filters. The odour and taste of water is removed by these filters is one undeniable fact. This makes it an ideal choice for home users. However, the only setback is its inability to remove inorganic pollutants.


Mechanical filters however, have the notoriety of removing physical impurities from water and lack the ability to remove chemical and micro-biological contaminants. This has relegated them to being used in conjunction with other types of filters.Perhaps the best technology used to purify water is reverse osmosis. This is owed to its ability to rid water of both chemical and physical sediments off water. They have the distinction of using 3-20 times the water they produce to ensure purity. In this method, water is forced through a semi-permeable membrane; owing to its thin membrane large particles are blocked.


The perfect water purification system is a blend of reverse osmosis and carbon fibre. The two methods when employed together can guarantee contaminant free water. An advantage is chlorine which cannot be purified by reverse osmosis can be absorbed by carbon. The odour and taste of water is equally not compromised.


So next time you want to install a water purifier, choose the technology that best fits your home.
