MANUFACTURED MEDIA USING WASTE ALUM SLUDGE FOR REMOVING PHOSPHORUS AND METHOD FOR MANUFACTURING THE MEDIA

摘要

PURPOSE: A filter material for a phosphorus removal, and a manufacturing method thereof are provided to manufacture a filter material having a high removing efficiency, a simple and eco-friendly process of manufacturing, and a low manufacturing cost. CONSTITUTION: A filter material for a phosphorus removal is manufactured by mixing and molding waste Alum sludge and inorganic material. The inorganic material is red clay and clay. The content of the waste Alum sludge is 10-20 wt%, the content of the red clay is 60-70 wt%, the content of the clay is 15-25 wt%.
