Application of Filter Press Cloth in Plate and Frame Filter Press for Domestic Sewage Treatment —— Xidiase's Solution
With the acceleration of urbanization, the discharge of domestic sewage is continuously increasing. How to efficiently and stably treat sewage and reduce environmental pollution has become an important task for sewage treatment plants. In the solid-liquid separation stage, the plate and frame filter press is widely used for sludge dewatering due to its mature structure and high filtration accuracy. The filter press cloth, as a core component, directly determines the separation efficiency and operating cost.
1. Challenges in Domestic Sewage Treatment Separation
Domestic sewage contains a large amount of organic matter, suspended particles, grease, and inorganic salts. The sludge has a high moisture content, making treatment difficult:
- Fine particles that easily cause clogging;
- Poor sludge dewatering performance, with high moisture content in the filter cake;
- Complex chemical composition requiring high acid and alkali resistance and corrosion resistance of the filter cloth.
This places higher performance demands on the filter cloth.
2. Role of the Plate and Frame Filter Press
The plate and frame filter press forms filtration chambers by alternating filter plates and filter frames, achieving solid-liquid separation under pressure. Its advantages include:
- High filtration accuracy : Effectively intercepts suspended solids;
- Good dewatering effect : Low moisture content in the filter cake, facilitating transportation and disposal;
- Stable operation : Adapts to various sludge conditions, suitable for large-scale domestic sewage treatment.
3. Advantages of Xidiase Filter Press Cloth
Xiamen Xidiase Filtration Materials Technology Co., Ltd. has been deeply involved in the filtration industry for nearly thirty years. It is a leading brand in the research and manufacturing of filtration materials (mesh belts) and the drafting unit of industry standards for belt filter press belts. For domestic sewage treatment, Xidiase has developed filter press cloths with the following features:
- Chemical corrosion resistance : Suitable for the complex acidic, alkaline, and organic environments in sewage;
- High permeability : Ensures rapid filtrate flow while effectively retaining impurities;
- High strength and wear resistance : Resistant to damage during long-term operation, reducing maintenance costs;
- Customized design : Provides different filter cloths such as monofilament, multifilament, and double-layer structures based on sludge particle characteristics to meet various plate and frame filter press application needs.
4. Actual Application Results
In sewage plant application cases, Xidiase filter cloth paired with plate and frame filter presses has brought significant improvements:
- Filtrate clarity significantly improved, meeting discharge or reuse standards;
- Sludge moisture content reduced 20-30% , greatly lowering transportation and disposal costs;
- Enhanced filter cloth durability, with service life extended compared to ordinary filter cloths by more than 30%; 以上；
- Stable and reliable operation, with significantly reduced equipment maintenance frequency.
5. Conclusion
Domestic sewage treatment is a key part of urban environmental protection. Plate and frame filter presses combined with high-performance filter cloths are essential for efficient solid-liquid separation. With strong R&D capabilities, complete testing and pilot production lines, and years of industry experience, Xidiase provides professional filter cloth solutions for customers. In the future, Xidiase will continue to support the green development of the sewage treatment industry through technological innovation and high-quality products.
