Porcelain sand
Porcelain sand has the characteristics of large specific surface area, strong dirt interception capacity, high water output rate, stable water quality and long filtration cycle. It can meet the advanced treatment requirements of the complex components of industrial wastewater and urban sewage. In view of the shortcomings of traditional filter materials, combined with the development experience of domestic new filter materials, kaolin, binder, pore former and preservative are used to calcinate at high temperature. It has the characteristics of white appearance, hard texture, uniform particles, developed micropores, and high porosity. It is widely used in single-layer, double-layer, three-layer filters and other types of filters (slow filter, fast filter, siphon filter) Tank, gravity filter) valveless filter, pressure filter, extracorporeal circulation filter, ordinary filter, mechanical filter, ion transport device, etc. as media, can treat various organic and inorganic industrial sewage, tap water, pure water, Soft water, especially suitable for boiler chemical water treatment and ultra-pure water.
