In the early days, the only filter material was natural quartz sand. With the continuous research and experiments, broken anthracite particles and other filter materials processed with natural materials, such as garnet filter materials, gradually appeared. The particle shape of garnet filter material is angular dodecahedron or quadrangular octahedron, which is angular and sharp. The particles of quartz sand filter material are oval. Long-term washing will make the particles of quartz sand filter smaller and smaller, reduce the porosity of particles, slow down the speed of water flow and make the filtration effect worse.
The specific gravity of garnet filter material is greater than that of quartz sand. When used as bottom filter material, garnet filter material can bear stronger pressure from water and water washing the bottom, and will not cause the floating phenomenon of filter material, so that the whole filtration system will remain stable.
