We offer a wide assortment of Pressure Sand Filter that we extensively used to filter water and remove suspended particle, color and odor from it. Pressure Sand Filter is an ideal solution for the systems with high sediment, silt, sand, and turbidity. The sand filters are specially designed to take care of the range of suspended impurities. The purpose of this filtration is to remove any particulate matter left over after flocculation and settling. The filter process operates based on two principles, mechanical straining and physical adsorption.

Process : The filter is equipped with certain valves and device which are incorporated in the outlet pipe system the propose of the device is to maintain a constant rate of filtration an important components of the regulation system is the venture mater which meager the bad resistant or loss of head when the resistant built up the operator open the regulation valves so as to maintain a steady rate of filtration when the loss of head exceed 1.3 meter it is uneconomical to run the filter. Normally the filter may run weeks or even month without cleaning when the bed resistant increase to such an extant that the regulation valves has to be kept fully open it is time to clean the filter bed since any further increase is drained off and the sand bed is clean by scraping of the top portion of the sand layer to a depth of 1 or 2 cm this operation may be carried out by unskilled laborers using hand tool or by mechanical equipment after several year of operation and say 20 or 30 scraping the thickness of the sand bed will have reduced to about 0.5 to 0.8 meter then the plant is closed down and a new bed is constructed.

The advantages of a slow sand filter are :

• Simple to construction and operation
• The cost of construction cheaper than that of rapid sand filters
• The physical chemical and bacteriological quality of filter water is very high when working ideally, slow sand filter have been shown to reduce total bacteria

Activated Carbon Filter are used to reduce chlorine, organics, color, tannin, objectionable tastes and odors, and dissolved organic chemicals from municipal and industrial water supplies. Automatic back-washing system removes the trapped contaminants within the filter bed and washes them down the drain. An activated carbon filter is a filter housing (either a cartridge filter housing or a granular activated carbon media filter is used for activated carbon filtration) containing granular activated carbon or an activated carbon block cartridge.

Process : Activated carbon filters are made in two types vertical and horizontal the principle of operation and method of working are similar and available in different size and capacities PWT filters are very efficient to reduced the suspended solids C.O.D.B.O.D. color organic matter and free chlorine the different time of filtering media lock grave silex work as sand / activated carbon rest bed in both filter water admitted at the top and passed away from the filter the incoming water is directed on a baffle to prevent disturbance of the sand /activated carbon bed.

Scope of supply : Mid steel pressurizes vessel painted inside with anti-corrosive paint and out side with two coats of red oxide primer with distribution and collection systems. Set of frontal piping and valve to control the inlet outlet wash out drain and air supply for back One charge of filtering media / activated carbon of required quality and size along with unit The carbon filter will have steam-bath reactivation arrangement

Application :

• Free filtration for water treatment plant and reverse osmosis plant
• Effluent treatment plant Drinking water scheme
