Great Pollution Holding Capacity Disc Filter

The Great Pollution Holding Capacity Disc Filter is mainly composed of the shell, filter head, disc, spring and other components. The shell is usually made of corrosion-resistant plastic-lined steel pipe, PE or stainless steel to ensure the long-term stable operation of the filter. The filter head shell is made of reinforced nylon, which not only ensures strength but also has good corrosion resistance.

 

The disc is the core component of the disc filter, usually made of materials with high wear resistance such as PP (polypropylene). The surface of the disc has a unique groove design, which allows the water flow to form a unique deep filtration effect when passing through. At the same time, the disc is tightly pressed between the springs and fluid pressure to ensure the stability of the filtration effect.

 

Working principle

The working principle of a Great Pollution Holding Capacity Disc Filter can be divided into a filtration stage and a backwash stage.

1. Filtration stage

In the filtration stage, the water flow enters the filter through the water inlet. Under the action of spring force and hydraulic force, the discs are tightly pressed together to form a continuous filter surface. The water flow flows through the grooves on the surface of the disc to the inner edge of the disc, passing through multiple filter points, thereby removing the impurity particles in the water. The filtered water flows out of the main channel of the filter for subsequent use.

2. Backwash stage

When the disc filter runs for a period of time, a certain amount of impurity particles will accumulate on the surface of the disc, resulting in an increase in filtration resistance. At this time, the system enters the backwashing stage. By changing the direction of the water flow and using the nozzle channel to spray the water flow, the disc rotates and is evenly separated. At the same time, the high-pressure water flow initializes the surface of the disc and flushes the trapped impurity particles out of the filter. After backwashing, the system automatically resumes to the filtration stage to continue the filtration work.

Maintenance

In order to ensure the long-term stable operation of the disc filter, regular maintenance and maintenance are required. Mainly include the following aspects:

Regularly check the operating status of the filter to ensure that all parameters are normal.

Regularly clean the inside of the filter and the surface of the disc to remove accumulated impurities and dirt.

Regularly check the status of wearing parts such as springs and seals, and replace damaged parts in a timely manner.

Regularly check and calibrate the backwash controller to ensure its accuracy and reliability.

 

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.
