GSL-2.5 Industrial high-speed sand filter

1 Max filtering area for GSL high speed sand filter: 19.63m2 2 Max filtering speed: 40m/h 3 Max filtering flow:785m3/h

Sand filter can guarantee high-grade water even in much suspection raw water situations.Its advantage include:high filtration rate.big processing water volume,small floor area and so on.Its operation can be the manual control and single unit auto control (or multi-unit),and it is determined by the user.The GSL series high speed filter are not only suitable for many suspension raw waters filtration,but also can improve the water quality in the periodical feeding system,enhance the water circulation-use save water.it is necessary for current industry water treatment.

This product is used in steel plant in the purification treatment of turbid water rolling,casting(containing iron oxide skin and oily),as well as the net recycling water system of filtration process.With actual experience,it has achieved many satisfactory results,deeply welcomed by factories.
