Water Filtration

Water Filtration maxit LWA is used as a filter material in a number of applications for filtering both municipal wastewater and drinking water. maxit LWA also performs well in a number of other filtering processes for dealing with industrial wastewater, fish farms and ecologically based purification methods. Nitrogen Removal Nitrogen removal is becoming increasingly important in the treatment of wastewater. This method uses maxit LWA as a platform for the growth of active bacteria in a biological process that takes place on the surface of the granules. The porous surface provides ideal conditions for bacteria growth and particle retention, and high abrasion resistance makes maxit LWA an outstanding filter material. Natural Treatment Systems Natural treatment systems or constructed wetlands (plant based treatments systems including reed beds) are also growing in popularity. These systems require few pipes and other expensive mechanical components and provide a good alternative to conventional treatment plants and installations. Natural treatment systems are well suited for use in sparsely populated areas. They are economical to build and operate,and represent an ecological treatment process without the use of chemicals. In a natural treatment system, sludge is first allowed to settle out before the water goes into a filter basin, where it passes through a layer of maxit LWA. maxit LWA has excellent properties for removing phosphorous, nitrogen, bacteria and organic materials. Since maxit LWA is a material which is specially graded into specific grain sizes, there is little danger that clogging will lead to impermeability. maxit LWA is employed as a filter material in constructed wetlands, sand filters,infiltration systems, final filtration and sludge removal and in just about any application where drainage and filter properties are required.
