An Overview Of Two Water Filtration Methods

Water filtration is really necessary to have clean and clear drinking water which is free from impurities and any contaminants. Most health conscious people utilize the water filtration method to prevent contamination of drinking water and its detrimental effects on our health.

Basically, there are two types of water filtration which are commonly used in top rated home water filters. These are carbon filters and reverse osmosis filters. Both of these methods use different techniques to purify the water, and to remove the contaminants like sediments, bacteria, chemicals and metals and odor. The carbon filters generally work by passing water through one or more filtering compounds while the reverse osmosis passes water through the layers of filtering screens to remove impurities and contamination and then uses the water for washing the screens.

Let's talk a little more about the working of the carbon filter.

The water is usually passed through granular activated carbon or a carbon block removing the sediments, organic compounds and the micro organisms. Some filters also use a micron membrane for removing silt and sand as an internal filtration stage. Many filtration companies are utilizing KDF which is a patented medium for fluid filtration. It is known for enhancing the capabilities of a carbon filtration system. Water can pass through up to about seven or eight levels of filtration. Each level eradicates the contamination which depends on the quality and size of the unit.

However, various studies show that the GAC and KDF which are used in combination within a filter unit have a greater capacity in removing contamination than carbon filtration alone. Carbon filter should be replaced based upon the manufacturer instructions when it is suspected to be faulty or past it's best..

Let's now look at the working of the reverse osmosis water filtration.

In this, water is first passed through a pre filter screen for removing sediments and larger particles from the water. After that, the water is passed through an even smaller screen to eradicate small particles like heavy metals, bacteria and many more. The third step is the passage of water through a carbon filter for completion of the filtration process. On the filtration screens, the contaminations get built up. As a result, the reverse osmosis systems use the water for washing out the screens which is known as backwashing. But water waste will result due to this process because as much as double the amount of water was purified.

These two water filtration systems are the most preferred systems in our society. Generally for home use, the carbon filter is best as it provides excellent services at a lower cost. However, reverse osmosis system is better, especially if any member of your family has a sensitive immune system.
