In-depth analysis: Application of filter press filter cloth and belt filter press in the treatment of domestic sewage sludge in municipal sewage treatment plants
——Xiamen Citius contributes to sludge reduction and resource utilization
With the acceleration of urbanization, the demand for domestic sewage treatment is constantly growing, and the pressure of handling **domestic sewage sludge (excess sludge)** produced by municipal sewage treatment plants is increasing. How to efficiently dewater and reduce the volume of sludge has become a key link in the sewage treatment industry. Among them, The combination of belt filter press and filter press filter cloth has become one of the mainstream technical solutions in the sludge dewatering field. Xiamen Citius Filtration Materials Technology Co., Ltd., as a leading industrial filter cloth manufacturer in the industry, has provided hundreds of sewage treatment plants with efficient and stable filter cloth solutions, helping to improve the quality and efficiency of environmental protection facilities.
I. Core objectives of municipal domestic sewage sludge dewatering
The ultimate purpose of sludge treatment is to separate the solid and liquid phases of high-water-content sludge to meet the requirements for transportation, composting, incineration, or landfill. The water content of general municipal sludge is as high as 95% or more, and it needs to be compressed to a water content of 60-80% (depending on the subsequent use) through mechanical dewatering.
Common dewatering processes include:
Belt filter press dewatering
Plate and frame filter press dewatering
Centrifuge dewatering
Among them, belt filter presses are widely used in medium and large-scale sewage treatment plants due to their continuous operation, high cost-effectiveness, and small footprint.
II. Working principle and advantages of belt filter press
Belt filter press through gravity thickening + multi-stage pressure dewatering + filter cloth operation achieves continuous sludge treatment and is suitable for treating domestic sewage sludge with strong fluidity and low solid content.
Its advantages include:
Continuous operation, high degree of automation
Strong processing capacity, low energy consumption
Compact equipment structure, simple maintenance
Adaptable to various types of sludge (municipal, industrial, septic tanks, etc.)
However, to ensure long-term stable operation, the key lies in the selection of suitable filter cloth materials and structural design 。
III. The key role of filter cloth in sludge treatment
In the entire pressure filtration process, the filter cloth is the only filtering medium that directly contacts the sludge and its performance determines:
Filtration speed
Filter cake dryness
Continuity of sludge discharge
Filter cloth life and cleaning frequency
Citius's sewage sludge dewatering filter cloth has the following technical advantages:
✅ Good balance between permeability and mud retention : Efficient dewatering while preventing sludge leakage;
✅ Resistance to chemical and microbial corrosion : Suitable for environments containing sewage chemicals;
✅ Excellent sludge peeling performance : Easy filter cake removal, reducing manual intervention;
✅ High tensile strength and tear resistance, stable structure : Adaptable to multi-roller high-pressure extrusion belt filter operation;
✅ Support customized processing : Provide services such as edge binding, anti-deviation guide belts, guide strip bonding, and hole punching design to adapt to various brands of equipment.
IV. Application case: Citius service sewage treatment plant project
Citius filter cloths are widely used in:
Municipal sewage treatment plants
Industrial park sewage treatment plants
Rural integrated sewage treatment equipment
Septic tank and sludge tank pressure system
Matching equipment includes:
Belt filter press
Plate and frame filter press
Screw press (filter screen accessories can be provided)
Customers generally feedback that Citius filter cloths are dewatering efficiency, filter cloth life, and operational stability have shown excellent performance, greatly reducing the maintenance frequency and replacement costs.
V. Conclusion: Green sludge treatment, starting from filter cloth
Sludge treatment is not the end point, but the starting point of environmental protection and resource utilization. Choosing a suitable high-performance filter cloth is the basis for ensuring the efficient operation of the entire sludge dewatering system. Xiamen Citius will continue to provide more professional and efficient filtration solutions for sewage treatment plant customers with innovative weaving technology and full-process services.
