Large Filtration Area Automatic Backwash Filter

Automatic backwash filters, as an advanced filtration technology, remove impurities from the filter screen through a specific mechanism to maintain their high-efficiency filtration performance. The Large Filtration Area Automatic Backwash Filter is further optimized on the basis of the traditional design, which greatly increases the effective filtration area per unit volume, thereby improving the overall filtration capacity and pollution capacity. This design innovation not only improves the processing efficiency, but also prolongs the operation cycle of the equipment, reducing the maintenance frequency and cost.

 

Working principle and technological innovation

The core of a large filtration area automatic backwash filter lies in its unique structural design. Usually, this type of filter adopts a multi-layer or special form of filter structure, which can greatly expand the filter surface area, so that even in the face of high-load contaminants, it can maintain a low pressure difference and smooth fluid passage ability. When the impurities accumulated during the filtration process cause the pressure difference to reach a preset value or a set time period, the system automatically activates the backwash program.

 

The backwashing process is usually achieved by changing the direction of the fluid. At this time, the original direction of water flow entering from the inlet, passing through the filter screen, and discharging from the outlet is reversed. The high-pressure clean water source or the circulating water flow of the system itself reverses the impact of the filter screen, initializing the impurities attached to the filter screen, and then these impurities are discharged through the sewage outlet with the wastewater. This process is not only efficient, but also restores the original filtration performance of the filter screen in a short time, ensuring continuous and stable water quality treatment.

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.
