Sand Filter

The sand filter, also called the quartz sand filter and sand filter is a filter that uses homogeneous quartz sand of equal particle size to form a sand bed as a filter carrier for three-dimensional deep filtration. It is often used for primary filtration. It mainly uses sand and gravel as filter media for filtration.

✦Description of Sand Filters

The gravel filter is the most common and effective filtering equipment used to remove organic impurities in water at home and abroad. It has a strong ability to intercept pollutants and is suitable for deep well water filtration, agricultural water treatment, and pre-treatment of various water treatment processes. This filter is the most effective in treating organic and inorganic impurities in water among all filters, and can supply water uninterruptedly. The working principle of the gravel filter is based on physical filtration, capturing and separating suspended matter and particles through the gravel filter layer. When the irrigation water passes through the filter layer, most of the impurities are filtered out, and the clean water flows into the irrigation system through the outlet. This filter is usually composed of multiple layers of gravel with different particle sizes. Larger particles are intercepted by the coarser gravel on the upper layer, and fine particles are adsorbed by the finer gravel on the lower layer. The graded filtration design improves the filtration efficiency and extends the service life of the filter.

✦In agricultural irrigation, the advantages of sand filters

1.Purify irrigation water: remove impurities such as suspended matter, organic matter and microorganisms in water to ensure the cleanliness of irrigation water. 2.Prevent equipment clogging:reduce the clogging of nozzles, drippers and pipes, and protect the life of irrigation equipment. 3.Reduce maintenance costs:By improving water quality, reduce equipment failures and maintenance costs caused by water quality problems. 4.Improve water resource utilization efficiency:Avoid water waste and improve irrigation efficiency. 5.To ensure the cleanliness of irrigation water, you only need to clean the sand and gravel layer regularly. 6.The sand and gravel filter has a long life and can be used for many years without replacement. 7.The filter medium of the sand and gravel filter can be natural sand and gravel and other materials, which is environmentally friendly and will not cause pollution.

‌In addition, the sand and gravel filter also has an automatic cleaning system, which triggers the cleaning operation according to the preset time interval or pressure difference to maintain the filtering efficiency of the filter layer. The fully automatic sand and gravel filter is equipped with an automated operation and control system, which reduces the operating burden of farmers and improves the stability and efficiency of the system.

Application

✦Applications of Sand Filters

The working principle of the sand filter is based on its unique sand bed filtration technology. It uses a sand bed composed of quartz sand particles with smaller particle size as the filter medium. Through the screening, interception, adsorption and degradation process of multiple filter layers, it effectively removes impurities in the water, ensures clear and pure water quality, and is widely used in various water treatment scenarios. Sand filters are widely used in many fields, including: 1.Pre-filtration and treatment of raw water for power generation, metallurgy, chemical industry, papermaking, beverages, etc. 2.Agricultural micro-irrigation system to ensure clean water sources, reduce clogging of irrigation equipment, and improve irrigation efficiency. 3.Industrial water treatment, such as circulating water bypass filtration system, surface water, groundwater turbidity reduction and color removal, etc. 4.Swimming pool water treatment to ensure that the water quality meets the swimming safety standards. 5.Urban water supply and drainage system, as a pre-treatment equipment, protects subsequent water treatment equipment and improves the quality of effluent. 6.Drinking water treatment, removes suspended matter, colloids, organic matter, bacteria, viruses, etc., and improves the safety and hygiene of water.
