Working of water filters

Water filters are one of those things that we use in our daily lives. It has always been viewed as just another thing. We really don’t give much of an important and take it for granted. There are very few who really know what these water purifiers have contributed.

Before buying the water purifiers, there are a few things that need to be done. One of those things is knowing the quality of the water. The quality of water differs from place to place. It is necessary to know the quality of water because it is with that information the water purifier can be decided.

Different types of water require different kinds of water filters. There are very few filters like aquatru water filter that can purify any kind of water. It is better to opt for these kinds of brands as it is not necessary to worry about water quality.

The working process

The water purifiers use various methods to purify water. Some of the purification methods that the purifiers use are the RO reverse osmosis, UV UltraViolet.

The Reverse Osmosis

 

Reverse osmosis is the of removing the dissolved organic solids in water. The process involves pressurizing the water and making it go through a semi-permeable membrane. When the water passes through a semi-permeable membrane, the impurities are filtered and is flushed out. This might sound simple, but this process involves various stages to get the best quality water.

The reverse osmosis purifiers include various parts such as the inlet valve, pre-filter, the reverse osmosis membrane, post filter, automatic shut off valve, check valve, flow restrictor, storage tank, and the drain or the outlet valve.

UV purifiers

The UltraViolet purification process is one the most commonly used methods to eliminate the microbes like virus and bacteria in the water.  In this process, the water that needs to be purified is exposed to a measured amount of Ultra Violet rays. These ultraviolet rays penetrate through the microorganisms, affect their DNA and totally eliminate them.

Mechanical filters

In the mechanical filtration process, the sediments are physically removed from the water.  This probably is the first process that the water is subjected to before going to other processes. The water is made to pass through filters. The filters have very tiny holes which remove the sediments from the water.

Ion Exchange

This is more of a chemical process. This process involves the elimination of calcium and magnesium ions to soften the hard water. The exchange resin is used to carry out the process. This process is generally used for commercial purposes like coffee machines.

Activated Carbon

The activated carbon purifiers are generally used for commercial purposes. They are used to purify large quantities of water. The activated carbon is a material with very high porosity. It is because of this that the activated carbon is able to absorb all the unwanted materials from the water. The activated is very effective in removing bad odor and bad taste. This why activated carbon is also used in air purifiers.
