Self-Cleaning Filter – intelligent differential pressure control for efficient and reliable operation.

Product Overview

The self-cleaning filter is the core equipment for boiler makeup water pretreatment.

 Utilizing advanced automatic 

cleaning and filtration technology, it efficiently removes suspended solids, sediment, particles,

 and other impurities

 from makeup water, effectively reducing water turbidity. This lays a solid foundation for subsequent advanced

 treatment processes, prevents pipeline blockage, scaling, and boiler corrosion caused by impurities, 

and ensures 

the safe, stable, and efficient operation of boiler systems.

Product Performance

· Fully Automatic Self-Cleaning – Cleaning and filtration occur simultaneously without interrupting

 water supply. 

No manual disassembly or cleaning required, significantly reducing labor costs.

· Adjustable Filtration Precision with High Interception Efficiency – Filtration precision can be adjusted 

according 

to water quality requirements, effectively removing fine suspended solids and ensuring consistently

 stable effluent 

quality.

· Low Operating Resistance & Energy Consumption – Optimized flow channel design minimizes pressure

 drop and

 energy consumption, making it ideal for continuous water supply conditions of boiler makeup water.

· Strong Anti-Pollution Capability – Resistant to clogging, with low operation and maintenance costs

 and long service life,

 offering excellent overall economy.

Technical Features

· Stainless Steel Filter Elements – Corrosion-resistant and wear-resistant, suitable for a wide range of

 water quality 

pretreatment requirements.

· Intelligent Control Module – Automatically initiates the cleaning program based on inlet-outlet

 differential pressure 

with precise and timely response, enabling unattended operation.

· Excellent Sealing Performance – Reliable overall sealing design with no leakage. Operating pressure

 and flow fully

 meet the technical standards for boiler makeup water pretreatment.

· Efficient Cleaning with Low Water Consumption – High cleaning efficiency with minimal water usage. 

Filter elements recover well after cleaning with no impact on filtration performance.

FAQ (Frequently Asked Questions)

Q1: What is the primary application of this self-cleaning filter?

A: This filter is specifically designed as core equipment for boiler makeup water pretreatment. 

It efficiently removes suspended solids, sediment, and particles from incoming water,

 reducing turbidity and protecting downstream boilers, heat exchangers, and advanced treatment

 systems from scaling, corrosion, and blockage.

Q2: How does the automatic self-cleaning process work without interrupting water supply?

A: The system utilizes fully automatic online cleaning technology. When the differential pressure

 reaches a preset threshold, the intelligent control module automatically initiates the cleaning 

program while the filter continues to operate — ensuring uninterrupted water supply with no 

need for manual disassembly or shutdown.

Q3: What triggers the cleaning cycle?

A: The cleaning cycle is automatically triggered by intelligent differential pressure control based on 

the inlet-outlet pressure differential. This ensures precise and timely response to actual contamination levels,

 enabling unattended, fully automatic operation.

Q4: What material are the filter elements made of, and why?

A: The filter elements are manufactured from stainless steel, offering excellent corrosion resistance and 

wear resistance. This makes them suitable for a wide range of water quality conditions and ensures

 long service life in demanding pretreatment applications.

Q5: Can the filtration precision be adjusted?

A: Yes. The filtration precision is adjustable according to specific water quality requirements,

 allowing the system to effectively remove fine suspended solids and maintain consistently stable 

effluent quality across varying feed conditions.

Q6: How much water is consumed during the cleaning process?

A: The system features high cleaning efficiency with minimal water consumption. 

The filter elements recover well after cleaning with no impact on filtration performance, 

making it a water-efficient solution for continuous operation.

Q7: What are the operating costs of this system?

A: Operating costs are low due to:

· Low operating resistance and optimized flow channel design for energy efficiency

· No manual cleaning or disassembly required, significantly reducing labor costs

· Long service life and strong anti-pollution capability, minimizing maintenance frequency

· Excellent overall economy with low operation and maintenance expenses

Q8: What water sources can this filter handle?

A: The filter is suitable for a wide range of water sources, including surface water, groundwater, tap water, 

and other water types, providing qualified pretreated influent for boilers, heat exchangers, 

and other downstream equipment.

Q9: What industries and applications is this filter best suited for?

A: The filter is primarily used for boiler makeup water pretreatment across multiple industries:

· Power Generation – thermal power plants, cogeneration boiler water treatment

· Chemical Industry – feedwater pretreatment for chemical process boilers and heat exchangers
