Regarding the common problems encountered during the operation of plate and frame filter presses in sewage treatment plants, such as incomplete sludge dewatering, high moisture content of filter cakes, and sticky filter cloths, our company's developed "Composite Sludge Enhancer" has achieved significant breakthroughs in practical applications, providing an efficient and cost-effective solution for the industry.

Analysis of Common Problems in Plate and Frame Dewatering

In the sludge dewatering process, plate and frame filter presses are widely used due to their large processing capacity and stable operation. However, the traditional process often encounters the following challenges:

High moisture content of the filter cake: After sludge pressing, the sludge remains in a viscous state and fails to reach the desired dryness level.

Severe filter cloth adhesion: The sludge adhering to the filter cloth makes it difficult to discharge, requiring frequent rinsing and increasing labor costs.

Low processing efficiency: The single filtration cycle is prolonged, which affects the overall production capacity.

The core technical principle of the sludge enhancer

The compound sludge enhancer developed by our company achieves performance breakthroughs through the following mechanisms:

Charge neutralization effect: In highly efficient cationic polymers, the negative charges of sludge colloids are neutralized, thereby destroying the hydration structure.

Skeleton construction function: Add porous media to facilitate the formation of water channels, thereby improving dehydration efficiency;

Surface modification technology: Forms a hydrophobic layer on the surface of the sludge particles, completely solving the problem of sticky filter cloth.

Sludge enhancer is a chemical agent that can alter the surface structure of sludge, reduce the solid surface load of sludge, decrease the specific surface area of sludge's surface, and damage the structure of bacteria. The main components of sludge enhancer include inorganic compounds, sludge surface structure modifiers, degreasing agents, wall-breaking agents, sludge surface treatment agents, and sludge stripping agents, etc. Sludge enhancer has the advantages of low dosage of the agent, low cost, breaking the bottleneck of sludge dewatering, achieving efficient concentration and dewatering, good treatment effect, and high cost-effectiveness.
