High-Speed-Filtration Quartz Sand Filter

The high-speed-filtration quartz sand filter is usually composed of a tank body, a water distributor, a water collector, an exhaust valve, a manhole, a sewage outlet, an inlet and outlet pipe fittings, etc. The tank body is filled with quartz sand of different particle sizes to form a so-called "filter bed". Water enters from the water distributor at the top of the tank body and is evenly distributed throughout the filter bed. As water flows through the quartz sand layer, particles and impurities are trapped, while cleaner water is collected through the water collector and discharged from the bottom of the tank body.

 

The working process of a high-speed-filtration quartz sand filter can be divided into three stages: filtration, backwashing, and positive washing.

2. Backwashing stage. As the filtration progresses, dirt gradually accumulates in the filter layer, resulting in a decrease in filtration efficiency. At this time, the filter needs to be backwashed to remove contaminants in the filter media. Backwashing is usually achieved by injecting air or water into the filter, which helps to loosen the filter media and wash away the trapped impurities.

3. Positive washing stage. After backwashing, a positive washing (also known as drainage) stage is required to remove fine particles remaining in the filter material. During the positive washing process, water enters the filter from the bottom, passes through the filter material layer, and is discharged from the top.

1. High efficiency. The quartz sand filter has good filtration efficiency and can effectively remove suspended solids and impurities in water.

2. Low cost. Compared with other filter materials, quartz sand is inexpensive and easy to obtain.

3. Simple maintenance. The backwash operation is simple, which can effectively remove accumulated impurities and prolong the service life of the filter.

4. Strong adaptability. Suitable for filtration under different water quality conditions, and has strong adaptability to changes in water quality.

 

The high-speed-filtration quartz sand filters are widely used in agricultural irrigation, industrial water treatment, swimming pool water treatment and other fields. In agriculture, they are mainly used to treat water sources such as groundwater, lake water or rainwater to meet the needs of crop irrigation. By reducing the content of suspended solids and harmful substances in water, filters not only protect the healthy growth of crops, but also avoid soil pollution.

 

 

In order to ensure the long-term and effective operation of the high-speed-filtration quartz sand filter, regular maintenance is necessary:

- Regularly check the pressure difference between the inlet and outlet. When the pressure difference reaches a certain value, backwashing should be carried out.

- When backwashing, attention should be paid to controlling the backwashing intensity to prevent the loss of filter material.

- Regularly check and clean water distributors and catchments to ensure that the water flow is evenly distributed.

- Regularly check the tightness of the tank and whether the valves are working properly.

- For serious pollution, chemical cleaning agents can be used for cleaning.
