1. Product specification
Quartz sand filter, scientific name: shallow medium filter, uses quartz sand as the filter medium to filter the water with high turbidity through granular or non granular quartz sand with a certain thickness under a certain pressure, effectively intercept and remove the suspended solids, organic matter, colloidal particles, microorganisms, chlorine, smell and some heavy metal ions in the water, and finally reduce the water turbidity It is a kind of high-efficiency filtration equipment for purifying water quality.

3. Working Principle
Quartz sand filter uses one or several filter media, operates at room temperature, resistant to acid, alkali and oxidation, and the PH application range is 2-13. The system is equipped with perfect protection devices and monitoring instruments, and has backwashing function. Dirt and other pollutants are washed away quickly with less water consumption. Full automatic function can be set according to user requirements. Under a certain pressure, the stock solution is flocculated, adsorbed and intercepted through the contact of the medium to remove impurities, so as to achieve the purpose of filtration. The fillers inside are generally quartz sand, anthracite, granular porous ceramics, manganese sand, etc. users can choose to use them according to the actual situation. The filtration accuracy is between 0.005-0.01mm, which can effectively remove colloidal particles and macromolecular organics.
It is mainly used to remove suspended solids in water. Cooperating with other water treatment equipment, the equipment is widely used in various water treatment projects such as water supply purification, circulating water purification and sewage treatment.
4. Application
It is mainly used for pre-treatment of turbidity removal, softened water, electrodialysis and reverse osmosis in water treatment, as well as surface water and groundwater. It can effectively remove suspended solids, organic matter, colloid, sediment, etc. in water.
Also can be widely used in electronic power, petrochemical industry, metallurgical electroplating, papermaking and textile, pharmaceutical dialysis, food and beverage, domestic drinking water, factory and enterprise water, swimming pool, etc. It can meet the needs of liquid filtration in various industries.
