Different Type of Water Filters and How do they Work

Do you know how water filters work?

Possibly you don’t.

We live in an age of science. Even beggars on the roads of cities have smartphones and tablets. The technological secrets involved with so many gadgets we have today is beyond our imagination. Even so, we do like to have a basic understanding of their working.

There are different types of water filters and sometimes, some of them are combined into a single unit.

1. The Basics of Water:

Courtesy of an unusual molecular structure, water is excellent at dissolving things. If you want to bust the mud from your clothes, just throw them in your washing machine with some soap or detergent and the water will pull the dirt away like a magnet. But there is a drawback to this too.

All of the water circulates through the biosphere in what we call the Water Cycle. One moment, it is carried away by the winds or rushing through a rivulet, the other it is streaming from your tap, sitting in a jug in your kitchen. But how do you know the water you want to drink is pure? If you want to be sure, you buy a water filter.

2. Physical and Chemical Filtration:

Water filters use several techniques to purify water. The physical filtration means cleaning water by removing larger and visible impurities. In more precise terms, a physical filter is a glorified strainer.

Another method of water purification is chemical filtration which involves passing water through a very light and active physical barrier that removes bacteria and other impurities.

3. Micron and Sub-Micron Filtration:

This is an estimate of how excellent the water filter is at removing bacteria, and other particles from the water smaller are better. A micron is around 1/150 the diameter of human hair. A water filter that eliminates impurities down to 6 or 7 microns will provide clean water. However, most of the bacteria, parasite, and giardia will escape through the pores of the filter.

4. Reverse Osmosis Water Filters:

A water filter must trap bacteria and other particles one or smaller micron to be beneficial at removing the microscopic impurities such as Giardia cysts and Cryptosporidia. A virus can not be completely removed by any filtration method. In theoretical studies, Reverse Osmosis can provide clean water but even a minute flaw in the organic strainer or membrane would allow bacteria to escape through the filtered water.

In Reverse Osmosis, water pressure is used to move water molecule through a strainer that has very small pores, leaving the large impurities behind. Clean water is collected from the clean side of the filter and the water containing containment is released down the drain.

The average RO water filter is a system consisting of sediment. Chlorine per filter, the RO membrane, the storage tank unit, and an activated carbon secondary filter. RO system wastewater. Three to five gallons of wastewater is thrown down the server for each gallon of clear water produced.

5. Solid Black Activated Carbon and GAC Filters

Activated carbon is the modified flecks of carbon that have been modified to increase their ability and surface area to absorb an extensive range of impurities. The two basic kind of carbon filters is Solid Black Activated Carbon Filter and Granular Activated Carbon Water Filter.

Containment reduction in Activated carbon filters take places by two process, physical removal of the impurities, obstructing any that are large enough to move through the filter (certainly, the filters with smaller strainers are more efficient); and a process called adsorption by which a number of dissolves are attracted and adsorbed by the carbon particles. The features of the carbon material such as surface area and chemistry, density, hardness, and pore size affect the working of adsorption.

Water runs through a filter where it is exposed to ultraviolet rays. UV rays destroy all virus and bacteria. However, how good the Ultraviolet filter works rely on the energy that the organism soaks. If the energy released is not high enough, the organisms DNA may only be mutilated rather than disrupted.

No water filter available in the market is perfect. So don’t forget to do some research before making the final choice.
