Sand filters are mainly used to remove suspended solids, impurities, and pollutants from water, and are widely used in the field of water treatment. The following are specific application scenarios:
sewage treatment
Sand filters are used in sedimentation tanks of sewage treatment plants to separate particles with a diameter of ≥ 0.2mm, with a treatment efficiency of 96% -98%, suitable for organic sand separation and lifting operations. ‌
Deep processing and preprocessing
Quartz sand filters remove suspended particles, colloids, and organic matter from water through quartz sand media, and are suitable for advanced wastewater treatment, water supply treatment, and industrial wastewater pretreatment. ‌
Industrial and agricultural water use
Sand filters are commonly used for industrial water pretreatment, agricultural irrigation water filtration, and physical filtration of urban water, which can achieve uninterrupted water supply. ‌
Special water quality treatment
Biological denitrification: Removing nitrate nitrogen from wastewater through the action of biofilms on the surface of filter sand. ‌
Chemical phosphorus removal: Used in conjunction with chemical agents, the sediment is captured by sand bed filtration to remove total phosphorus. ‌
Sand filters can be divided into quartz sand filters, activated carbon filters, and other types due to different filter materials. Their core function is to intercept pollutants through the filter layer and ensure water quality safety. ‌
