Filter Sand (for rapid and slow filtration)

Filter Sand(for rapid and slow filtration)@To use Filter Sand is a basic filtration method of water purification. Importance of Filter Sand, to work for physical treatment (catching the turbidity component) in rapid filtration and for biological treatment in slow filtration, is widely well-known. For the purpose of making the filtration rapider and water collection ratio more in recent years, the filter layer component and flow direction have been improved, the improved result and further improvement in quality are desired. We, as a manufacturer of Filter Sand, have investigated the quality control and manufacturing technology thoroughly since 1965.
