Detailed Description
Application of industrial filter cloth in belt press filter for pile foundation sludge treatment
With the acceleration of urban infrastructure construction, pile foundation engineering has become increasingly common, and the problem of pile foundation construction sludge treatment has become increasingly prominent. Pile foundation sludge is characterized by high water content, strong viscosity, and high organic matter content. If not properly treated, it will not only occupy a large amount of land resources but may also cause environmental pollution. Belt press filter, as a highly efficient sludge dewatering equipment, shows good adaptability in pile foundation sludge treatment, and industrial filter cloth is one of the key core materials for achieving efficient dewatering.
I. Challenges in Pile Foundation Sludge Treatment
The slurry produced during pile foundation construction is mainly composed of mud and sand, cement residue, concrete slurry, and some groundwater, forming a special slurry with fine particles, high water content, and easy equipment blockage. The treatment of this type of sludge often faces the following difficulties:
- Low dewatering efficiency, sludge is difficult to form cakes;
- Difficult filtrate recovery, turbid water quality;
- Filter cloth is easily blocked and worn, resulting in high operation and maintenance costs.
II. Adaptability Advantages of Belt Press Filter
Belt press filter gradually reduces the water content of sludge through gravity dewatering, wedge zone pre-pressing, S and shaped pressing, suitable for scenarios with strong continuity and large processing capacity, especially suitable for on-site dewatering treatment of large quantities of sludge at pile foundation construction sites.
III. The Role and Selection Characteristics of Industrial Filter Cloth in This Application
In belt press filter, the performance of industrial filter cloth directly affects the dewatering efficiency and filter cake quality. For pile foundation sludge treatment, the ideal filter cloth should have the following properties:
- Good water permeability and mud retention : It can quickly discharge the filtrate and effectively retain fine particles;
- Strong anti-blocking ability : The structure is compact but not easy to scale, reducing the frequency of shutdown cleaning;
- Strong wear resistance and tensile strength : To cope with repeated tightening and high-pressure friction in the pressing zone;
- Easy to clean and regenerate : Improve the service life of the filter cloth and reduce operating costs.
According to Xiamen Citius (Xiamen Citius) Filter Materials Technology Co., Ltd.'s engineering experience, double-layer spiral mesh, modified monofilament mesh, or high-strength polyester series filter cloth can be used. In structural design, combined with high-strength wear-resistant edge reinforcement, hydrolysis-resistant coating, and edge wrapping design, effectively improves the stability and service life of the filter cloth.
IV. Actual Application Effectiveness
In several municipal infrastructure pile projects, Xiamen Citius (Xiamen Citius) filter cloth with belt press filter runs stably, and the average sludge water content can be reduced from the original 80% to 60% or less, the filtrate is clear and can be reused for pile mixing construction or other construction water. The service life of the filter cloth is as long as 3 months or more, and the maintenance cost is significantly reduced.
V. Conclusion
Pile foundation sludge treatment, as a key environmental protection link in infrastructure construction, will be paid more attention to in the future under the requirements of construction environmental protection compliance. The optimized design and high-performance guarantee of industrial filter cloth will provide strong support for efficient dewatering and reduction treatment. As a total solution provider for filtration systems, Xiamen Citius (Xiamen Citius) will continue to innovate filter cloth performance to contribute to green construction and resource recycling.
