Smooth-Working Disc Filter

The smooth-working disc filter, as a shining pearl in water treatment technology, plays a pivotal role in industrial circulating water, sewage treatment, drinking water purification and other fields with its high-efficiency filtration performance and stable working state.

Let's demystify the disc filter and explore the essence of its structure. This filter is mainly composed of a series of flat, porous plates called "filter discs", which are stacked together in a certain order to form multi-layered filter units. The tiny holes in each filter disc are like countless miniature portals, allowing only certain-sized particles to pass through and blocking large particles out.

Working principle

1. Filtration stage

- The piston on the upper part of the filter element holder presses the discs.

- Water enters through the water inlet.

- The water flow passes through the centrifugal disc, and the centrifugal force of the water flow throws large-particle impurities on the inner wall and concentrates them on the top of the filter unit. The water carrying a small amount of impurities is then filtered through the discs, which reduces the cleaning frequency of the discs and achieves the effect of saving water.

- The water carrying fewer impurities continues to enter the deep filtration through the gap between the compressed discs, and the filtered clean water flows out of the disc lumen to the water outlet.

2. Backwash stage

- Backwash water flow (filtered pressurized water) is sucked from the lower water outlet of the filter element holder. The piston on the upper part of the filter element holder is lifted up, and the discs are loosened.

- The backwash water flow is sprayed from the small holes on the filter element holder cylinder to the scattered discs, causing the discs to rotate laterally and vibrate vertically. During the rapid rotation of the discs, the water flow thoroughly cleans the discs from the inside out, and finally the cleaning water is discharged from the sewage outlet.

- After the backwash is completed, the piston is reset, the discs are pressed, and a new round of filtration is started.

Parameters

Technical characteristics

1. High-efficiency filtration. The disc filter has high filtration accuracy and retention capacity, which can effectively remove solids and suspended solids from water.

2. High degree of automation. The disc filter adopts a fully automatic control system, which can automatically switch between working and backwashing states without manual intervention.

3. Energy saving and low consumption. Due to the use of automatic backwashing technology, the waste of water resources is reduced and operating costs are reduced.

4. Reliable operation. The disc filter has a long service life and stable operating performance, ensuring continuous water discharge from the system.

Application fields

The smooth-working disc filter is widely used in various water treatment occasions, including industrial circulating water, swimming pool water, landscape water, municipal water supply, agricultural irrigation and other fields. Especially in occasions with high water quality requirements, such as electronics industry, pharmaceutical industry, food and beverage industry, disc filters can play an excellent filtration effect.

Maintenance and upkeep

In order to ensure the normal operation and prolong the service life of the smooth-working disc filter, regular maintenance and upkeep are required. It mainly includes cleaning the filter, checking the wear of the discs, replacing the damaged discs, etc. In addition, it is also necessary to regularly check the operating status of the control system and the integrity of the electrical components to ensure the normal operation of the system.

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.
