Quartz sand pressure filter applies only to the requirements of the filter water turbidity ≤3 mg / liter industrial, rural, urban, living quarters and other water supply facilities. Wherein when the double layer filter for direct filtration water turbidity often maintained at 60 mg / liter or less, and should raise the case of the filter before the coagulant. For precipitation filtration, water turbidity is ≤15 mg / l. Single-layer media filter applies only to water turbidity ≥15 mg / liter of precipitation water filtration. When the raw water suspended solids content of less than 30 ~ 50mg / L, can be used as ion exchange softening (or desalting) process pretreatment equipment. Can also be used for water requirements are not the main process water treatment as a coarse filter. Purity quartz sand high purity quartz sand SiO2≥99.5-99.9% Fe2O3≤0.001%, using high-quality natural quartz stone, carefully selected, fine processing. Size range 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm quartz sand prices, according to user requirements. Uses: manufacture of glass, refractories quartz sand purchase, smelting ferrosilicon refining quartz sand, quartz sand metallurgical flux, ceramics, abrasive materials, quartz sand casting molding, etc., using its strong acid etching medium capacity building , extracting acid and acid of concrete mortar.
