High Grade Automatic Backwash Filter

The high grade automatic backwash filter is a water treatment equipment used to remove suspended particles, sediment and other impurities from water. It uses the principle of backwash to remove dirt and impurities from the filter element through reverse water flow, thus maintaining the efficient operation of the filter. It is widely used in industry, agriculture, medicine, environmental protection and other fields, and is of great significance for improving production efficiency, ensuring product quality, reducing labor intensity, and reducing environmental pollution.

Working Process

The working process of the high grade automatic backwash filter is as follows:

- Filtration. Water flows into the filter through the filter element (usually a mesh or porous material). Suspended particles, sediments, and other impurities are captured by the filter element.

- Differential pressure monitoring. The filter has a built-in differential pressure switch or sensor to monitor the differential pressure on both sides of the filter element.

- Backwash trigger. When the pressure difference reaches the preset value, the pressure difference switch or sensor will trigger the backwash process.

- Backwash valve open. Backwash valve open, reverse water flow through the filter element, flushing away dirt and impurities.

- Discharge. The dirt and impurities washed down are discharged through the sewage outlet to the filter.

- Backwash valve closed. After the backwash process is completed, the backwash valve is closed and the filter resumes normal filtration operation.

- Replace the filter element according to the manufacturer's recommendations to maintain optimum filter performance.

 

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.
