Brief on Water filtration process

Water filtration process is a method in which particles are removed from water using mechanisms such as flocculation, straining, surface capture and sedimentation. In straining method, strainers are used which consist of a thin physical barrier film that is usually made up of steel or plastic. Strainers are generally used to filter out large objects such as fish and leaves from the water. There is another type of strainer known as micro strainer that is mostly used to filter out fine particles out of water such as algae and silt.

Filters, as commonly known in a water filtration process generally consists of a system through which most of the particles in the water are captured.

There are different types of filters used in water filtration processes. One such filter used in filtration is known as slow sand filter. Slow sand filter consists of a bed of sand that is situated within a filter shell. The impurities are captured on the surface of the sand surface forming a debris and the water is filtered out from the bottom.

Activated carbon filters are another type of filtration filter which can be used to remove chlorine and organic compounds from water supplies. The technique or method used in this filtration process is known as chemical adsorption. These carbon filters have to be activated before they are used for water filtration.

Another way to filter the water is through chlorination and de-chlorination. In chlorination, chlorine is added to the water to kill bacteria, viruses and other unwanted microbial organisms. The temperature and pH level of water affects the effectiveness of chlorination. Although chlorination kills bacteria and microbial organisms, it can react with other components of water and create unwanted compounds.

The feed water is filtered before passing it for further industrial processing.
