Our water treatment quartz sand filter media features uniform particle size, smooth surface, and is predominantly white or nearly transparent. It has stable chemical properties, is resistant to both acids and alkalis, and is not prone to corrosion. The main component of the quartz sand filter media is silicon dioxide, with a content typically over 98%. This ensures that it does not react with other chemicals in high pH water treatment environments, thereby guaranteeing the water quality is not further contaminated by the filter material.
Filtering is one of the primary functions of water treatment quartz sand. In a water filtration system, quartz sand is packed to form a certain thickness of filter layer. When turbid water, such as water containing silt and sand, flows through the quartz sand filter medium, the suspended particles and impurities like silt are trapped in the gaps between the quartz sand grains. These pores vary in size, and the water is filtered step by step. Larger particles are first blocked by the larger pores on the surface, while smaller particles flow deeper into the filter layer and are captured by finer pores. 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 waterworks, quartz sand filtration is a crucial step that effectively removes most impurities from the raw water, ensuring the basic clarity of the output water.
In addition to filtering suspended impurities, water treatment quartz sand can also remove some harmful substances from the water through adsorption. Although quartz sand has a relatively low adsorption capacity, its surface is rough with microscopic grooves and a distribution of charges. These microstructures allow quartz sand to adsorb certain heavy metal ions and a small amount of organic pollutants in the water. When water containing these impurities flows through the quartz sand filter layer, some ions and pollutants will adhere to the surface of the quartz sand, thereby reducing the concentration of impurities in the water. Although its adsorption capacity is limited, quartz sand is not used alone in the entire water treatment process. Instead, it is used in conjunction with activated carbon filter media and other filtration materials to synergistically enhance the purification process, significantly improving water quality.
