Detailed Description

Filter press filter cloth, plate and frame filter press, sewage sludge dewatering
Filter press type: Plate and frame filter press
Application industry: Sewage treatment plant
Material description: Sludge dewatering

I. Introduction: Challenges facing municipal wastewater treatment

With the rapid development of urbanization, the sludge production of municipal sewage treatment plants is increasing continuously. Sludge contains a large amount of organic matter, microorganisms, and heavy metal pollutants. Dewatering of sludge is difficult and costly due to its large volume. Therefore,Sludge dewateringis an important aspect of municipal sewage treatment plants that cannot be ignored.

In the sludge dewatering process,plate and frame filter presshas been widely used in municipal sewage treatment plants due to its high-efficiency solid-liquid separation capability.Filter press filter clothas a key filtering medium, plays a vital role in sludge dewatering efficiency, filter cake moisture content, and filter cloth life.

II. Advantages of plate and frame filter presses in sludge dewatering in municipal sewage treatment plants

1. High-efficiency solid-liquid separation, reducing sludge moisture content
Plate and frame filter presses squeeze water out of the sludge through high-pressure filtration, forming a filter cake and significantly reducing the sludge moisture content.

  • The moisture content of the sludge after pressing can be reduced to50% or lesssignificantly reducing the burden of subsequent sludge disposal.
  • The choice of filter cloth directly determines the filtration speed, filter cake peeling performance, and the stability of equipment operation.

2. Adaptable to different sludge characteristics, stable filtration performance
The sludge produced by municipal sewage treatment plants has complex components, containing a large amount of organic matter, inorganic matter, bacteria, etc., and the physicochemical properties of the sludge vary depending on the influent water quality and process conditions. Plate and frame filter press withhigh-performance filter clothcan maintain efficient filtration in different sludge treatment processes, ensuring that the effluent water quality meets the standards.

3. Excellent filter cake peelability, improving processing efficiency
Municipal sludge has high adhesion and is easily retained on the surface of the filter cloth, affecting filter cloth regeneration. High-quality filter cloth hasgood peeling performanceand can quickly peel off the filter cake, reduce the frequency of filter cloth cleaning, and improve equipment operating efficiency.

III. Technical advantages of filter press filter cloth in sludge dewatering

1. Precise filtration, improving sludge solid-liquid separation effect
The particle size distribution of suspended matter and solid particles in municipal sludge is wide, and the filter cloth needsprecise pore size controlto ensure efficient retention of solids and good water permeability.
✅ Multi-layer structure weaving technology:The outer layer has high-density filtration, the middle layer enhances compressive strength, and the inner layer increases permeability, effectively achieving solid-liquid separation.
✅ Uniform pore size distribution:It can effectively prevent solid particles from penetrating while ensuring that the filtrate passes quickly, improving overall filtration efficiency.

2. Corrosion-resistant, strong chemical resistance, suitable for complex environments
Sludge contains acids, alkalis, and various organic and inorganic compounds. The filter cloth is exposed to such an environment for a long time, which puts higher demands on the corrosion resistance of the material.
✅ Excellent acid and alkali resistance:Can work stably inpH 2-12 range to ensure long filter cloth service life.
✅ Anti-oxidation, anti-microbial corrosion:The surface of the filter cloth has been specially treated to prevent microbial growth and reduce the aging speed of the filter cloth.

3. Strong filter cake peelability, reducing residual attachment
The pressed sludge filter cake usually has high viscosity. High-quality filter cloth aftersmooth surface treatmentimproves the peelability of the filter cake.
✅ The filter cloth is not easy to block:Prevent fine particles from embedding in the fibers, improving the regeneration capacity of the filter cloth.
✅ Smooth filter cake peeling:Greatly reduces the frequency of filter cloth cleaning and extends the service life of the filter cloth.

IV. Filter cloth selection points: Matching the needs of municipal sludge dewatering

1. Pore size and filtration accuracy matching
The particle size of municipal sludge is uneven, and the appropriate pore size should be selected according to the particle size distribution of the sludge.

  • Pore size is too large:Fine particles will penetrate with the filtrate, affecting the effluent water quality;
  • Pore size is too small:Will reduce the filtration speed and increase the equipment operation burden.

2. Acid and alkali resistance and durability
Chemical reagents are often added during municipal wastewater treatment, such as lime,PAC、PAM Wait, the filter cloth must haveResistance to strong acids and alkalisPerformance, to prevent material aging or damage caused by long-term use.

3. Tensile and wear resistance, suitable for high-pressure environments
The high-pressure filtration process of the plate and frame filter press will exert a large tensile force on the filter cloth, and the filter cloth should haveGood tensile strengthandWear resistanceto adapt to high-intensity operating environments.
