The Dual Media Filter utilizes combination of Filter Media and Anthracite for higher flow rates with a smaller footprint. High filtration velocities are achieved by proper selection of Media, and designing of Distribution and collection systems. These filters are offered in Mild Steel, FRP or SS construction with face piping and associated Valves.
Side Stream filters are most commonly used for Cooling Tower water filtration. They use relatively coarse sand and other granular media to remove particles and impurities in the Cooling tower water.
Water flows through the filter medium under pressure and the suspended particles are trapped in the sand matrix. These filters are typically designed with high filtration velocities.
These filters are the most popular method for removal of turbidity from water. The Pressure Sand Filter consists of a multiple layer of sand with a variety in size and specific gravity. These Filters are designed to remove turbidity and suspended particles present in the feed water with minimum pressure drop. These Filters are custom designed to suit the process requirement. These filters are offered in Mild Steel, FRP or SS construction with face piping and associated Valves.
ConstructionThe Pressure sand filter consists of a pressure vessel either vertical or horizontal, 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 uniformly collect the filtered water.
ProcessRaw water flows down wards through the filter bed and as the suspended matter, which is treated by addition of a coagulant like alum or poly electrolyte, is retained on the sand surface and between the sand grains immediately below the surface. There is steady rise in the loss of head over a period of time and the flow reduces once the pressure drop across the filter is excessive.
The filter is then taken out of service and cleaning of the filter media is effected by flow reversal also called as backwash. To assist in cleaning the bed, the backwash operation is sometimes preceded by air scouring by way of agitation through the under drain system. The air scouring agitates the sand with a scrubbing action, which loosens the intercepted particles. The filter is now ready to be put back into service.
Fluid Systems offers Chemical handling and Dosing Systems for dosing Coagulants like Lime. Ferrous Sulfate, PAC, Alum and Feed Conditioning chemicals like Anti-scalant, Antioxidant, Membrane cleaners etc. Dosing systems are Skid mounted, compact and rugged, engineered to handle and work efficiently under highly corrosive and varying conditions.
The areas of application includeTypical Dosing systems consist of Metering type pumps with varied material of construction to suit the chemical handling. All Dosing Systems can be upgraded to a high level of automation for link up to a localized PLC or client's DCS as required.
Pre-engineered designs conform to International safety norms with respective to spillage and containment.
The Iron Removal Filters are designed to remove the Excess Iron content present in the feed water with minimum pressure drop.
Most iron filtration systems operate on the principal of oxidizing the iron (oxidation) to convert it from a ferrous (dissolved or soluble) to a ferric or undissolved state. Once the iron is converted to ferric state, it is precipitated on a filter bed.
For low Iron content in feed water, the Filter consists of Manganese Zeolite, where the iron is oxidized to insoluble hydrated oxides that are removed by the mechanical filtering action of the Zeolite bed.
