Water filtration is the last step in pretreatment of surface water. Filters are grouped into pressure filters and gravity filters based on whether water to be filtered flows under pressure through the filter or by gravity. Fine or coarse sand, anthracite, garnet and granular activated carbon are used as the filter media. Ion Exchange offers the widest range of filters that include Multimedia Pressure Sand Filter and Gravity filters, Auto Valveless Gravity Filters and Continuous Sand Filters, Activated Carbon Filters and Filter Pak for raw water and waste water filtration
