Industrial Use Automatic Backwash Filter

The industrial use automatic backwash filter is mainly composed of the cylinder body, filter screen, water flow guide valve, sewage outlet, differential pressure controller and other components. The cylinder body is usually made of 304 or higher standard stainless steel material to ensure corrosion resistance and strength. The filter screen is a key component, and its pore size can be selected according to the needs of different industries to meet different filtration accuracy requirements.

 

Working principle

1. Filtering process

When untreated water enters the filter cylinder from the inlet, the water first passes through the filter screen, which intercepts impurities such as suspended solids and particles in the water, allowing cleaner water to pass through the filter screen and flow out from the outlet. As the filtration process continues, the accumulation of impurities on the filter screen will cause the pressure difference between the inlet and outlet to gradually increase.

2. Backwash process

When the pressure difference reaches the preset value, the pressure difference controller triggers the backwash operation. First, the water flow guide valve is switched to cut off the water inlet of the filter, and then the sewage outlet is opened to initialize the filter surface from the inside of the filter screen. In this way, the impurities intercepted by the filter screen will be washed away by the water flow and discharged from the barrel with the water flow from the sewage outlet.

3. Automated operation

The entire backwash process is completed automatically by the built-in control system without manual intervention. Once the backwash is over, the water flow guide valve is readjusted to the filtration state, and the filter continues to perform normal filtration operations.

Companies that implement environmental protection measures are often able to improve their brand perception and attract more customers and consumers.

 

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.
