Water Filtration Use Auto Backwash Filter

The core working principle of the Water Filtration Use Auto Backwash Filter is to intercept and separate impurities in water through the filter medium. When water enters the filter from the inlet, it will pass through the filter screen or other filter media, the impurities are trapped, and the clean water flows out from the outlet. As the filtration process continues, impurities will gradually accumulate on the filter medium, causing the pressure of the filter to gradually increase. When the pressure reaches the set value, the backwash process is automatically triggered.

 

In the backwashing process, by switching the direction of the water flow, the water flow enters the filter from the outlet in the opposite direction, and the impurities accumulated on the filter medium are washed away, and the impurities are discharged from the sewage outlet. The backwashing process is usually fast and efficient, which can restore the filtration performance of the filter in a short time and ensure the continuous and stable operation of the system.

 

Structural composition

1. Filter tank

The filter tank is the main part of the auto backwash filter, usually made of high-strength materials, such as stainless steel, carbon steel, etc., to withstand water pressure and ensure the stability of the equipment. The tank body is equipped with filter media and related support structures.

2. Filter media

Common filter media include filter screens, filter elements, etc. Filter screens can be selected with different pore sizes and materials according to needs to adapt to different water quality and filtration requirements. Filter elements are usually made of fibrous materials, which have higher filtration accuracy and dirt holding capacity.

3. Control system

The control system is a key part of the automatic backwash filter, which is responsible for monitoring the pressure, flow and other parameters of the filter, and automatically triggering the backwash process according to the set conditions. The control system usually adopts intelligent design and has functions such as automatic adjustment and fault diagnosis.

4. Sewage device

The sewage discharge device is used to discharge the sewage that carries impurities during the backwashing process, usually including sewage valves, sewage pipes, etc. The sewage valve can be automatically opened and closed according to the instructions of the control system to ensure the timely discharge of sewage.

5. Inlet and outlet valves

The inlet and outlet valves are used to control the inflow and outflow of water, ensuring that the water flow direction is correct during normal operation and backwashing of the filter.

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.
