Sand Filters

Sand filtration is the most frequently used, robust method to remove suspended solids from water. The Filter consists of a multiple layer of sand with a variety in size and specific gravity. Fluid Systems Manufactures complete range of Gravity Sand Filters & Pressure Sand Filters in different sizes and materials both Manually operated or fully Automatic. The Filters are designed to remove turbidity and suspended particles present in the feed water with minimum pressure drop.Water enters the filter and percolates through the filter bed. The Suspended matter present in the water comes in contact with the media particles and are trapped on the top of the bed. Clean water then goes via the filtration nozzles through the filter outlet.Cleaning of this filter is done periodically by backwashing. Water is introduced in the reverse direction of the service flow, i.e; from the outlet nozzle upwards causing suspension of the turbid material in the filter bed & finally flushing out through the backwash valve. The Filter is then down rinsed & clear water is taken in the system.Different types of Filter Media are used depending on the raw water quality and the treated water quality required.Fluid systems offer a complete range of seven bedded filtration systems custom made to achieve the turbidity level of less than 1 NTU & Suspended solids less than 10 ppm. The Filtration beds comprises of the coarsest beds starting from Pebbles of 40 65 mm size to the finest layer of fine sand 0.8 to 1.6 mm size.pplicationPretreatment to all forms of Industrial water treatment and potable Water treatmentAdvantageEasy to operate & practically no Maintenance.Better filter quality at higher flow rate than conventional filters.
