          Skytop cooperates with Dalian University of Science and Technology and other research institutions to develop the volcanic rock biological filtering materials, which are used for the wastewater treatment in municipalities, wastewater treatment in industries, sanitary waste treatment and natural water purification for drink, etc. The materials are raw volcanic rocks from the Changbai Mountain in Dandong, which is a high-quality mine of the volcanic rock biological filtering materials. The materials, with the absorbability and ion exchange property of the activated carbon, can form biological membranes rapidly, which are the good carriers of the tiny organisms. The materials are used in the aerobic and anaerobic biofilters to process the wastewater in municipalities, wastewater in industries, sanitary waste and high concentrated organic wastewater; the materials can be used as the filter media instead of activated carbon, arenaceous quartz, anthracite coal, expanded clay and shale ceramist, and the materials can be used to deeply process the tail water after the secondary system of the sewage treatmentplant.
