PRESSURE SAND FILTERS
Pressure Sand Filters are used with Pressure vessels with sand and are widely used in industrial filtration applications. During the cleaning cycle, called “backwash”, the bed is lifted (or “fluidized”) to loosen the filter media and release trapped dirt which is removed in the backwash flow. Backwash is generally carried out with higher velocity preferably at 30 – 40 M3/hr/M2. Filter backwash may include air scour to help loosen packed dirt in the media bed. Air scouring also helps in reducing the backwash flow rate and in turn the Back Wash Water requirement. After the backwash cycle, the bed is allowed to settle before the filter is returned to service (i.e., normal flow). A “filter-to-waste” cycle is used following the settling to assure the filtration media has sufficiently re-stratified and that any loose dirt is removed from the underdrain / collectors.
The Pressure Sand Filter contains of a many layer of sand with a diversity in size and specific gravity. These Filters are designed to remove turbidity and suspended particles current in the feed water with least pressure drop. These Filters are custom designed to suit the procedure requirement. Sand filters are used as a step in the water treatment procedure of water purification. There are three key types; rapid (gravity) sand filters, upward flow sand filters and slow sand filters. All three methods are used lengthily in the water industry throughout the world. The first binary require the use of flocculant chemicals to work effectively while slow sand filters can produce very high quality water with pathogens subtraction from 90% to >99% (depending on the strains), taste and odour without the want for chemical aids. Sand filters can, separately from being used in water treatment plants, be used for water purification in singular households as they use capitals which are obtainable for greatest folks. These filters are the most popular technique for removal of turbidity from water. The Pressure Sand Filter contains of a several layer of sand with a variety in size and specific gravity. These Filters are considered to remove turbidity and suspended particles present in the feed water with least pressure drop. These Filters are custom intended to suit the process requirement. These filters are accessible in Mild Steel, FRP or SS construction with face piping and associated Regulators.

Sand filters are widely used in water cleansing and remove postponed matter by a completely diverse method. Instead of the water passing through smaller orifices through which particles cannot pass, it runs through a bed of filter medium, typically 0.75 mm sand 750 mm deep.

Pressure Sand Filter is an ideal solution for the systems with high sediment, silt, sand, and turbidity. Our unique design ensures the maximum utilization of the surface area, lesser pressure drop across the pressure bed and effective elimination of the impurities. The strength, stability and micro-porous character of filtration media make sand filter suitable for virtually every application in the water treatment industry.
These Filters are available in FRP (Fibre Reinforced Polymer), Mild Steel Epoxy Painted (MSEP) or Rubber Lined (MSRL) and Stainless Steel 304 or 316 Grade.
Filters are available in standard sizes ranging from 300 mm dia up to 3000 mm dia with straight height of 2000 mm for Flow Rate starting from 1000 Lts per hour up to any size.Read more
