Quartz sand is widely used in the field of water treatment, mainly due to its excellent physical and chemical properties. Firstly, quartz sand has excellent particle stability and wear resistance, enabling it to effectively remove suspended solids, sediment and other impurities from water during the filtration process. In addition, the pore structure and specific surface area of quartz sand enable it to provide a larger contact area during the water treatment process, thereby enhancing the filtration efficiency of water. Secondly, quartz sand is not easily dissolved during the water treatment process and does not release substances harmful to water quality, which ensures the safety and reliability of the treated water.

In order to further enhance the water treatment effect of quartz sand, researchers have also explored its combined use with other materials in recent years. For instance, they have combined quartz sand with activated carbon to strengthen its ability to remove organic matter and heavy metals. In conclusion, quartz sand, as an important material for water treatment, has a very broad application prospect and will play an even more significant role in environmental protection and water resource management in the future.
