What Is a Rapid Sand Filter?

The shallow media filter is composed of multiple standard high-speed sand cylinder units. It has a unique water distributor and water collector inside, and has a unique two-way automatic flushing valve, which can realize multiple standard high-speed sand in normal system operation. The cylinders are individually backwashed one by one, and fully automatic program control. It has the advantages of small backwash water, convenient installation and easy operation. The equipment has a large flow and requires no maintenance. According to different user requirements, there are two series of vertical and horizontal. Suitable for water quality treatment of industrial and civil circulating water systems.

1. Small size, easy installation and space saving. Can be installed outdoors without building a house, saving construction cost:

(1) The floor space is extremely small, and it can be installed indoors and outdoors, and it can also be installed in layers up and down, with strong adaptability;

(2) Compact structure and space saving;

(3) The product has good anti-corrosion performance and can be installed indoors or outdoors.

2. The equipment has good anti-corrosion performance and long service life.

3. Large amount of filtered water, good filtering effect, fast filtering flow rate and high filtering accuracy.

4. Automatic backwashing: Backwashing is automatically identified by the intelligent control system.

1. Filtration of industrial water --- there are certain system requirements for water quality. Such as: filtration of oxygen lance water, boiler, heat exchanger water supply in steel plants, etc., can filter out impurities in the water to avoid blockage of several nozzles in the pipeline.

2. Filtration system for industrial circulating water.

3. Treatment of raw water --- It can filter surface river water, lake water, seawater, reservoir water, well water, and urban water supply with urban tap water as the source to remove sand, suspended matter, algae, organic matter, etc.

4. Agricultural irrigation --- especially suitable for high-flow, high-impurity water sources, such as irrigation of farmland water, irrigation of lawns in parks and golf courses.

5. Water treatment in food processing industry, paper industry, circulating water treatment in power plant industry, etc., pretreatment of pure water for industrial and medical use. Recycling of industrial production water, industrial wastewater treatment.

6. Industries such as aquaculture, swimming and water parks ^[1] .
