Industrial Quartz Sand Water Filter/Multimedia Filter Tank for Water Treatment
What′s multimedia filter?
Miltimedia filter is a kinf of using quartz sand(quartz sand and anthracite or activated carbon) as the filter medium of the filter. It is to use one or several of filter medium,under certain pressure, make concentrate through the medium, to remove impurities,so as to achieve the purpose of the filter. Inside of packing is company: quartz sand, anthracite coal.
Activated Carbon Filter is the most common method of treatment for dechlorination and removal of colour, odor, Organic impurities & Residual chlorine from water, through adsorption of the compounds that cause these problems.
Activated Carbon Filter operates through adsorption. Adsorption is directly related to the surface area of the media. This great surface furnishes a huge adsorption area for organic as well as chlorine molecules to attach themselves. This intermolecular attraction between the carbon surface and the substance that is being adsorbed can be altered by increasing the density of the carbon or by reducing the distance between the carbon surface and the substance being adsorbed.
PRESSURE SAND FILTER PROCESS
Raw water is passed through the pressure sand filter, the filter media is supported on gravel bed that consists of multiple layers of Graded quartz sand, Fine sand, Super fine white sand and pebbles of progressively larger sizes. During the filtration cycle the filter bed retains the dirt and suspended particles from the water and accumulates within the filter the water and accumulates within the filter bed. As the filtration progress the filter media gets loaded with retained suspended particles, this results in a continuous increase of pressure drop across the filter, when a predetermined pressure drop level is achieved the filter is shut down for cleaning.
