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.

The gravity sand filter or rapid gravity filter are most commonly used in Municipal water purification plants worldwide. They use relatively coarse sand and other granular media to remove particles and impurities that have been trapped in a floc through the use of flocculation chemicals. Water and flocs flows through the filter medium under gravity and the flocculated material is trapped in the sand matrix.

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.
