Shallow Sand Filter

It is a professional pre-treatment equipment for mechanical filters and multi-media filters in water purification systems, mainly used for pre-filtration to remove suspended solids and solid particles in raw water. The equipment shell can be made of various materials, including PE, rubber-lined steel, steel with plastic spraying, epoxy anti-corrosion steel and stainless steel, to adapt to different water quality and working conditions.

The filter uses high-quality manganese sand as the core filter medium. When the system is in filtration state, raw water flows through the manganese sand filter bed from top to bottom. The filter bed automatically forms a top-loose and bottom-dense layered structure during filtration, which can effectively intercept suspended solids, colloids, iron, manganese, organic matter and other pollutants in the water, and the purified water flows out from the bottom of the equipment.

1. Adopts high-quality manganese sand as filter medium, with low filtration resistance, large specific surface area, strong acid and alkali resistance, and excellent anti-pollution performance.

2. Optimized filter material and equipment structure design realize adaptive operation, with strong adaptability to raw water concentration, operating conditions and pre-treatment process requirements.

3. The filter bed automatically forms a top-loose and bottom-dense state during filtration, which ensures stable and reliable effluent quality under various operating conditions.

4. The filter medium can be fully dispersed during backwashing, with excellent cleaning effect and no residual impurities.

5. It has the advantages of fast filtration speed, high filtration precision and large dirt-holding capacity, and can effectively remove iron, manganese, bacteria, viruses, pesticides and other pollutants in water.

• Multiple shell material options, strong corrosion resistance, long service life, and can adapt to various corrosive water quality environments.

• Efficient and comprehensive purification effect, can effectively remove a variety of pollutants in water, especially for iron and manganese removal has an excellent effect.

• Adaptive operation design, no need for frequent manual parameter adjustment, suitable for different raw water quality and working conditions.

• Excellent backwashing effect, low daily maintenance cost, stable long-term operation, and low operation energy consumption.

• High filtration efficiency, large dirt-holding capacity, long filter material replacement cycle, and low overall operation cost.

• Industrial process water: Widely used in electric power, electronics, petroleum, chemical, metallurgy, textile, paper making, food and other industries for process water purification.

• Domestic and municipal water: Applied in tap water plants, domestic water supply and municipal water supply systems to ensure water quality meets drinking standards.

• Circulating water treatment: Used in swimming pool circulation treatment systems, cooling circulation water purification systems to maintain water quality stability.

• Wastewater advanced treatment: For in-depth treatment of industrial wastewater and municipal wastewater to meet reuse or discharge standards.

• Water treatment pre-treatment: As pre-treatment equipment for ion exchange softening and desalination systems, to protect the subsequent precision treatment equipment.
