Various filtering techniques that water filters use

Water filters are a common requirement of the present times, whether that be your house or your office. Contrary to the popular belief, purified or filtered drinking water isn’t enough; the rest of the water that you use every day should be filtered as well, especially if you are in a region where soft, clean water is rarely available. Naturally, manufacturers and health experts across the world have come together to design and develop water filters that can filter gallons of water every day, not only for drinking purposes but other chores as well.

With the advancement in technology, the mechanism of water filtration has been revolutionized as well and today, you can find hundreds of water filter models in the market that follow various techniques for filtering water. Let’s take a look at the most common and popular techniques that are used in water filters:

 

Reverse osmosis

This is a very old technique of filtration and was initially used for cleaning water. Gradually, the technique was incorporated into water filters and since then, this is one of the most popular ways of filtering water. A filter membrane is added to the filter machine and the water that comes in contact with the membrane is filtered of the mineral particles via the process of reverse osmosis. The process is highly successful in filtering out mineral contaminants like lead, mercury, iron, etc. along with harmful bacteria and viruses. Additionally, it can stop chlorine from passing through.

 

Though this is the easiest and cheapest of the ways to filter water, yet there is a major drawback to this technique. Along with harmful metals, the process also blocks out important minerals that are needed by the body, thereby causing a deficiency in the body. Moreover, the process of reverse osmosis also causes the waste of a lot of water.

 

Activated carbon

Commonly known as activated charcoal, it is often used in the filtering machines as a filtering agent. Small blocks of activated carbon are placed within the machine and all water coming in contact with the blocks get stripped of all harmful chemicals and contaminants without hampering the mineral content of the water. Naturally, you get soft water, but with the necessary nutrients. However, the charcoal blocks have to be replaced at regular intervals to ensure proper filtering.

 

Ceramic filtering

Marine fossilized remains are used in this case as the filtering agent. They are quite effective in filtering the larger sized particles, including pathogens. Naturally, they are often used in commercial/outdoor filters that intend to provide water free of pathogens. However, this type of filtering isn’t quite suitable for homes where you need to filter out pathogens, contaminants as well as chlorine, which cannot be filtered by a ceramic filter.

 

The above three techniques have become extremely popular in the present times and people often prefer to choose a filter that either work on reverse osmosis or activated carbon for their homes. However, www.waterpurifiermalaysia.com techniques of water filtration can also be used with quite a success. UV filters, ionized filters, etc. are also commonly available in the market.
