Porcelain sand filter is widely used in single-layer filter, multi-layer filter, mechanical filter to filter media, handling all kinds of industrial waste water, industrial water, city water, city sewage, water, soft water, can also be used as a biological filter treatment of organic sewage material. Can also be used to filter dust collector dust filter handle various sub-industries, boiler soot. 
 Rare earth rare earth porcelain sand filter modifier added, the use of scientific formula, specially shaped and heat baked with the traditional quartz sand and anthracite filter media, compared with the following advantages: 1, spherical surface, porosity, , filtration rate is generally 15 ~ 20 m3 / h, bed head loss can reduce the filter height, to save power consumption and infrastructure costs; 2, the particles evenly structured, easy to clean, backwashing strength is generally 12 ~ 20 l / m2. s, backwash water consumption can be reduced by 30 ~ 50%; 3, large pore volume, surface area, interception capacity, usually 9 ~ 10 kg/m3, is quartz sand of 1.2 to 1.5 times ; 4, high strength, wear small, not damaged, the service life of up to 15 years; 5, corrosion resistance, no loss, no pollution, no leaching of harmful substances to ensure the quality and stability. Widely used rare earth porcelain sand filter filter, mechanical filter to filter media to effectively deal with various water and sewage, flue dust can also be used to do filter, filter to remove all kinds of industrial dust and boiler dust.
