Water treatment quartz sand filter media features uniform particles and sharp edges, predominantly in white or yellow hues. It boasts stable chemical properties and excellent resistance to both acids and alkalis. The primary component of quartz sand filter media is silicon dioxide, with a content typically exceeding 98%. This ensures that it remains unattacked by chemicals in complex water treatment environments, thereby guaranteeing that water quality is not further contaminated due to the filter material.

Filtering is one of the core functions of water treatment quartz sand. In water filtration systems, quartz sand is filled to a certain thickness to form a filter layer. As turbid water flows from top to bottom through the quartz sand filter layer, suspended particles, silt, algae, and other impurities are intercepted by the tiny pores between the quartz sand grains. These pores vary in size, creating a multi-layer filtration effect. Larger particles are blocked first by the larger pores on the surface, while smaller particles are captured by finer pores as they move deeper into the filter layer. After passing through the quartz sand filter layer, the originally turbid water becomes clear and transparent, with a significant reduction in suspended matter content, providing a good foundation for subsequent deep treatment. For example, in urban water purification plants, quartz sand filtration is a crucial step that effectively removes most impurities from the raw water, ensuring the basic clarity of residential drinking water.

In addition to filtering suspended impurities, water treatment quartz sand can remove some harmful substances in the water through adsorption. Although quartz sand has a relatively weaker adsorption capacity than activated carbon and other adsorbents, its surface is not completely smooth and features some microscopic irregularities and charge distributions. These unique structures allow quartz sand to adsorb certain heavy metal ions and a small amount of organic pollutants in the water. As water containing these harmful substances flows through the quartz sand filter layer, some ions and pollutants are adsorbed onto the surface of the quartz sand, thereby reducing the concentration of harmful substances in the water. Although the adsorption amount is not significant, quartz sand is not used alone in the entire water treatment process but is employed alongside activated carbon filter media and other filtration materials. This协同作用 with other treatment processes significantly improves water quality.
