What are the advantages of garnet filter media and quartz sand filter media?
Garnet filter material is a new type of filter material. It is relatively less in use than the quartz sand and manganese sand used before. How high is the use value of garnet filter material?
The Mohs hardness of the garnet filter material is between 7.5-8, while the quartz sand filter material is between 6-7, and the hardness is lower than that of the garnet filter material. The hardness of the filter material determines the quality of the wear resistance. If the quartz sand filter material is used for a long time, it will undergo continuous washing and sedimentation of suspended particles, which is prone to breakage.
The angular dodecahedron and quadrangular 3-octadecahedron presented by the garnet filter media particles are mainly characterized by polygonal and sharp edges. The quartz sand filter material presents an oval shape, and long-term water washing will make the quartz sand filter material become very small, and the water flow speed will become slower after the porosity of the particles becomes smaller, so the filtration effect is poor.
The flushing pressure that quartz sand can withstand is only 8-12 minutes, while the flushing pressure of garnet filter material can be 15-20 minutes. It can be seen from the above that the garnet filter material has a faster filtering speed and a better filtering effect. Garnet sand filter media can maintain porosity better than quartz sand in the same filter.
