Effect
Physical filtration and chemisorption: Quartz sand removes suspended matter, colloid and organic matter from water through physical filtration and chemisorption. Physical filtration is through the screening effect of quartz sand, the large particles in the water are blocked outside the filter layer to ensure the cleanliness of the water quality. Chemical adsorption is the use of quartz sand on the surface of the interaction between negative and positively charged ions in water, the adsorption of these ions, reduce the ion concentration in the water.
To improve the water quality: Quartz sand can effectively remove the suspended solids in the water, particulate matter and impurities, significantly reduce the content of the suspended solids in the water, improve water quality of clarity and transparency. This is particularly important for industrial water, domestic water and urban water supply systems to provide efficient filtration.
