Efficient Backwashing Disc Filter

The efficient backwashing disc filter is an type of efficient, space-saving, easy-to-maintain and long-life water treatment equipment. It adopts the design of superimposing multiple annular filter discs with grooves. The working principle of this filter is to let water flow in from the outside, and the grooves between the filter discs effectively intercept solid impurities in the water to achieve the purpose of filtration. When backwashing is required, the direction of water flow is reversed, and it is flushed from the inside to the outside to remove the trapped dirt.

 

Disc filters are widely used in various industrial and commercial water treatment scenarios, such as cooling water systems, irrigation, sewage treatment and drinking water pretreatment, due to their fast filtration speed, high backwashing efficiency, space saving, simple maintenance and long life.

Characteristics of efficient backwashing disc filter

1. Efficient filtration

The disc filter adopts a design of stacking multiple filter discs, so that the groove edges between the filter discs can effectively intercept solid impurities in the water and achieve high-efficiency filtration. In addition, the disc filter also adopts backwash technology, which can remove the trapped dirt in a short time and ensure the normal operation of the filter.

Step 2 Save space

The disc filter is designed by stacking multiple filter discs, which makes the filter volume relatively small and saves space. In addition, the disc filter can also be customized according to actual needs to adapt to different installation environments and usage needs.

3. Easy maintenance

The disc filter has a simple structure and is easy to maintain. The filter disc of the filter can be disassembled and cleaned, and no professionals are required to operate it. In addition, the disc filter is also equipped with an automatic control system, which can realize automatic operation and remote monitoring, reducing maintenance costs and difficulties.

4. Long lifespan

The disc filter uses high-quality materials to make the filter disc, which has good corrosion resistance and wear resistance. At the same time, the disc filter also adopts advanced manufacturing technology and strict quality control to ensure the stability and reliability of the product. Therefore, the disc filter has a long service life, which can reduce the frequency of replacement and maintenance costs.

 

Application of efficient backwashing disc filter

1. Cooling water system

In industrial production, the cooling water system is an indispensable part. The disc filter can be used for the inlet and return of the cooling water system to remove solid impurities and suspended solids in the water and protect the normal operation of the system. At the same time, the disc filter can also reduce the maintenance cost of the system and prolong the service life of the equipment.

2. Irrigation

Agricultural production requires a lot of water resources for irrigation. However, because the water source contains various solid impurities and suspended solids, direct use will cause damage to crops. The disc filter can be used for water source treatment in agricultural irrigation to remove solid impurities and suspended solids in water and ensure the growth and yield of crops.

3. Sewage treatment

With the acceleration of urbanization and the development of industrialization, the problem of wastewater discharge has become increasingly serious. The disc filter can be used in the primary treatment stage of wastewater treatment to remove solid impurities and suspended solids in the water, reducing the difficulty and cost of subsequent treatment. At the same time, disc filters can also be used in the water outlet of wastewater treatment plants to ensure that the quality of the effluent meets environmental standards.

4. Drinking water pretreatment

The safety of drinking water is related to people's health and life safety. The disc filter can be used in the pretreatment stage of drinking water to remove solid impurities and suspended solids in the water, reducing the difficulty and cost of subsequent treatment. At the same time, disc filters can also be used in direct drinking water equipment in homes and public places to provide safe and healthy drinking water.

 

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.
