Media Filtration Systems

Media Filtration Systems has two parts. They are Pressure Sand Filter and Activated Carbon Filter. These are described bellow.

Pressure Sand Filter

Pressure sand filter consists of a pressure vessel-this could be either vertical or horizontal-fitted with a set of frontal pipe work and valves, graded silica quartz sand supported by layers of graded under bed consisting of pebbles and gravels, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to collect filtered water.

Raw water flows down wards through the filter bed and as the suspended matter- which has usually been treated by addition of a coagulant like alum- is retained on the sand surface and between the sand grains immediately below the surface. There is steady rise in the loss of head as the filter process continues and the flow reduces once the pressure drop across the filter is excessive.

Activated Carbon Filters

Activated Carbon filters are using for the Removal of Chlorine and Microorganisms thorough adsorption. Definite grade of high quality activated carbon with specialized design of distribution and collection systems will offer maximum efficiency of the removal of chlorine and ensuring long life in the carbon. Activated carbon filtration is most effective in removing organic contaminants, chlorine etc. Because organics are often responsible for taste, odor, and color problems.

ACF Unit is a FRP/MSRL vertical pressure vessel. Internally it is fitted with strainer on bottom collecting system. The unit is fitted with SS frontal pipe work & MPV externally. A granular activated carbon is charged on the supporting media of Coarse & Fine Salix.
