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.

1. Filtration stage. The water to be treated enters from the top of the filter, passes through the quartz sand filter layer, and the gap between the filter materials gradually decreases, and finally reaches the water collection device at the bottom. During this process, suspended solids and impurities in the water are trapped on the surface and inside of the filter material.

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.

Advantages

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.

 

Application and impact

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 addition, quartz sand filters can also help reduce water waste and improve water utilization. This is of great significance in dealing with water scarcity. As technology advances, more efficient filter materials and designs continue to emerge, quartz sand filters will continue to play an important role in the future.

 

Maintenance

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.

 

FAQ

1. Q: What is the function of a filter?

A: The main function of a filter is to remove solid particles, impurities, and harmful substances from liquids or gases, in order to achieve purification, clarification, and protection of equipment.

2. Q: How to choose a suitable filter?

A: When choosing a filter, factors such as the properties of the material being filtered (e.g., viscosity, temperature, corrosion), required filtration accuracy, processing capacity, operating pressure and medium, as well as the type, material, size, and installation method of the filter should be considered.

3. Q: What is the working principle of a filter?

A: The working principle of a filter mainly relies on physical screening, deep interception, absorption, or chemical reactions to remove impurities or harmful components from the material being filtered.

4. Q: How to maintain and care for a filter?

A: Maintenance of filters includes regular cleaning or replacement of filter elements, inspection of seals and fasteners, maintaining stable operating pressure, and avoiding overloading. Specific methods should be referenced from the filter's instruction manual and maintenance guides.

5. Q: What is the service life of a filter?

A: The service life of a filter depends on its working environment, processing volume, and filtration accuracy. Generally, when the filter's pressure drop reaches a certain value or the filtration effect decreases significantly, it needs to be replaced or cleaned.

6. Q: What should be paid attention to during filter installation?

A: During filter installation, attention should be paid to the directionality, ensuring that the fluid enters and exits from the correct ports. Also, the piping system should be cleaned before installation, and the filter should be securely fastened and sealed as required by the instructions.

7. Q: What is the replacement cycle for filters?

A: The replacement cycle for filters depends on their working conditions and filtration requirements, and is usually indicated by pressure difference indicators or timers. When the filter's pressure drop reaches the set value or the filtration effect decreases, it should be replaced in a timely manner.
