2025-03-04

Municipal sewage treatment plants generate a large amount of sludge every day, among which primary and secondary sludge have high moisture content and are difficult to dewater. Effective dewatering treatment of sludge is crucial. Belt press filters have become the mainstream equipment for sludge dewatering due to their continuous operation, large processing capacity, and low energy consumption, while high-performance filter fabrics are key factors affecting dewatering efficiency. Xiamen Xiadiya Filter Material Technology Co., Ltd. focuses on industrial filter materials and has developed filter cloth products that are highly permeable, resistant to chemical corrosion, anti-blocking, and high-strength wear-resistant, specifically targeting the characteristics of municipal sludge treatment. These products can effectively improve sludge dewatering efficiency, reduce sludge moisture content to 75%-80%, extend the service life of filter cloths, and reduce equipment maintenance costs. Xiadiya filter cloths have been widely used in domestic and international sewage treatment plants, contributing to the reduction, resource utilization, and harmless treatment of sludge.

Preface

With the acceleration of urbanization, the capacity for municipal sewage treatment continues to improve, but at the same time, the amount of sludge generated during the sewage treatment process is also increasing significantly. The disposal and resource utilization of sludge have become one of the key challenges in the field of environmental protection.Belt Press FilterDue to its efficiency, continuous operation, and strong processing capacity, it is widely used in sludge dewatering. As the core filtering medium,Industrial Filter Cloth, it directly affects the sludge dewatering effect, the moisture content of the filter cake, the stability of equipment operation, and the operation and maintenance costs.

Xiamen Citius(Xiamen Citius)Filtration Material Technology Co., Ltd. focuses on the research and development and manufacturing of filtration materials, providinghigh-performance filter cloth, assisting sewage treatment plants in optimizing sludge dewatering processes, improving sludge reduction effects, and reducing sludge disposal costs. This article will delve into the characteristics of municipal sewage sludge, the working principle of the belt press filter, and the technical advantages of Citiusfilter cloth and its application effectiveness in sludge dewatering.(Xiamen Citius)The technical advantages of filter cloth and its application effectiveness in sludge dewatering..

1. Characteristics and Dewatering Needs of Municipal Sewage Treatment Sludge

Municipal sewage treatment plants mainly useactivated sludge method, biological membrane method, and other biological treatment processes, which generate a large amount of residual sludge while removing pollutants. Sludge is mainly divided intoprimary sludge (settled sludge) and secondary sludge (biological sludge), which has a high moisture content, exhibits a certain fluidity, and has a large volume when untreated, leading to high transportation and disposal costs.

(1) Primary Sludge (Settled Sludge)

Primary sludge is composed of solid particles formed by the sedimentation of sewage in the primary settling tank, containing a considerable amount of organic and inorganic matter, and usuallyhas good dewatering performance.However, due to itstendency to decay and produce foul odors, it needs to be dewatered as soon as possible.

(2) Secondary Sludge (Biological Sludge)

Secondary sludge is the residual sludge produced after microbial treatment in the activated sludge system, with a high moisture content and fine particles,making dewatering difficult.Due to the small size of the sludge particles, they are prone toclogging the filter cloth, affecting the dewatering effect, so selecting the appropriate industrial filter cloth is crucial.

2. The Role of Belt Press Filter in Sludge Dewatering

(1) Working Principle

The belt press filter is a type ofefficient, continuously operating sludge dewatering equipment, and its workflow mainly includes:

  1. Sludge Conditioning: By addingPAC(Poly Aluminum Chloride),PAM(Polyacrylamide), and other chemical agents, the coagulation of sludge is enhanced, improving filtration performance.
  2. Gravity Dewatering Zone: After the sludge enters the equipment, it first discharges most of the free water through the filter cloth in the gravity zone, forming an initial filter cake.
  3. Wedge Dewatering Zone: Through slight mechanical squeezing, the sludge is further dewatered, reducing moisture content.
  4. Pressing Dewatering Zone: Under high-intensity pressure, the moisture in the sludge is further squeezed out, ultimately forming a filter cake with a lower moisture content.

(2) Equipment Advantages

  • Large processing capacity, suitable for the continuous operation needs of municipal sewage plants.
  • High degree of automation in operation, reducing manual intervention.
  • Low energy consumption and lower operating costs.

, however, the dewatering efficiency of the belt press filter is closely related to the performance of the filter cloth. Ifthe filter cloth is clogged, has insufficient tensile strength, or poor drainage performance, it may lead to a decrease in dewatering efficiency and even affect equipment operation. Therefore, selectinghigh-performance filter cloth, is crucial for optimizing sludge dewatering.

3. Technical Advantages of Citius(Xiamen Citius)Filter Cloth in Sludge Dewatering

As a leadingbrandin the industrial filtration materials industry, Citius(Xiamen Citius)focuses on the research and development of efficient filter cloth, providing a series of specially optimized filter cloth for the characteristics of sludge dewatering.Belt Press Filter) High Efficiency Dewatering Performance

(1Citius

filter cloth adopts(Xiamen Citius)a special weaving structure.Special weaving structure Improve the water discharge rate of sludge, allowing the sludge cake to form faster, significantly reducingMoisture content, and reducing the subsequent treatment costs of sludge.

(2) Excellent chemical resistance

Municipal wastewater treatment plants commonly usePAC,PAMchemical agents for sludge conditioning, ordinary filter cloths are prone to performance degradation due to chemical erosion. (Xiamen Citius)The filter cloth hasGood chemical corrosion resistance, can operate stably for a long time under the action of sludge conditioning agents, maintaining filtration effectiveness.

(3) Strong anti-blocking ability

To address the issue of fine sludge particles easily blocking the filter cloth, (Xiamen Citius)adoptsspecial surface treatment technology, reducing the embedding of sludge particles in the filter cloth fibers, improving permeability, making equipment operation smoother, and extending the service life of the filter cloth.

(4) High-strength wear-resistant design

Due to the operation of the belt press filter under high pressure, the filter cloth needs to have sufficient tensile strength and wear resistance. (Xiamen Citius)The filter cloth useshigh-strength fiber materials, maintaining good durability even in continuous operation environments, reducing maintenance costs from frequent replacements.

IV. Application Effects and Industry Practices

filter cloth adopts(Xiamen Citius)The filter cloth has been applied in multiple municipal wastewater treatment plants and has achieved good results:

  • The moisture content of sludge is reduced to75%-80%., significantly reducing the volume of sludge, lowering transportation and landfill costs.
  • Improve dewatering efficiency, making the cake easier to peel off, smoother equipment operation, and reduced maintenance costs.
  • Extend the service life of the filter cloth, reducing replacement frequency and improving economic benefits.
