●Self cleaning filter water treatment working principle
The self-cleaning filter uses a specific mechanical structure, the power of the water flow itself or external auxiliary equipment to automatically clean the surface of the filter. This design allows the filter to maintain high-efficiency filtering performance after long-term operation, reducing maintenance costs and downtime
●self cleaning filter water treatment Application areas
Self-cleaning filters are widely used in many industries or sectors such as industry, agriculture, and municipal administration, especially in systems that require continuous operation and do not want frequent shutdowns, such as petroleum, chemical, metallurgy, environmental protection, mining, pharmaceuticals, food, papermaking, etc.
●Main types
(1.) Self-cleaning pipeline filter
This type of filter can effectively remove particulate impurities in the water and improve the quality of circulating water, but there may be some safety issues in actual use, which need to be noted.
(2.) Self-cleaning rotary screen filter
The impurities are intercepted and cleaned by rotating the screen, which is suitable for processing larger particles of impurities
●Structural composition
Self-cleaning filters are usually composed of carbon steel or stainless steel cylinders, stainless steel brushes, stainless steel wedge-shaped filter screens, pressure and drain valves, etc.
●Cleaning mode
(1.)Brush cleaning: directly clean the filter surface with a rotating brush.
(2.)Directional cleaning: use water flow to guide impurities to the edge of the filter screen, and then use a scraper mechanism to remove them.
●Precautions
1. During installation, ensure that the direction of the arrow on the housing is consistent with the direction of the water flow.
2. Select the appropriate material and model according to actual needs.
3. Non-standard products can be designed and manufactured according to the technical conditions provided by the user.
●FAQ
Q: As a core component of modern water treatment systems, what technical advantages do you have for self-cleaning filters?
A:1. High-efficiency filtration and automatic cleaning: 304 stainless steel wedge-shaped filter (adjustable pore size 10-300 microns) with a rotating brush system can work continuously without stopping for cleaning. For example, the Rotorflush submersible filter pump can still maintain smooth flow when treating 200L/minute of sewage under a 300-micron filter.
2. Corrosion-resistant materials are suitable for complex water quality: For highly corrosive wastewater (such as iron slag and weakly acidic media) in industries such as steel and electroplating, 316L stainless steel or special coating technology is used to extend the life of the equipment to more than 10 years.
3. Intelligent control and low maintenance cost: Support PLC timing control, pressure difference sensing to start cleaning mode, and match hydraulic/motor drive system to achieve fully automated operation, reducing the need for manual intervention by 70%.
Q: What is your core value proposition as a supplier?
A: Through modular design + intelligent control system, we help customers reduce water treatment operating costs by 30%-50%, while meeting the ISO14001 environmental management system and industry-specific emission standards (such as GB 8978-1996 Comprehensive Wastewater Discharge Standard).
Q: What are your typical application scenarios and industry cases?
| Industry | Difficulties in treatment | Solutions and Results |
| Steel industry | High concentration of iron slag, oxidation and rust leading to excessive color | After installing the ZYT series self-cleaning filter, the effluent color was reduced to nearly transparent, and the SS removal rate was ≥95%. |
| Dyeing/electroplating | Wastewater containing complex organic matter and heavy metals | The CODcr reduction rate reached 85% and the nickel ion concentration was ≤0.1mg/L. |
| Municipal water supply | Algae growth and particle blockage | The Rotorflush self-cleaning water inlet filter operated continuously for 6 months in open water without biofilm contamination. |
