Deep dewatering of industrial sludge is a crucial step in sludge treatment, and the selection of chemicals directly affects the dewatering effect and cost. This article will introduce the types of commonly used chemicals in the deep dewatering of industrial sludge and their advantages and disadvantages. At the same time, it will analyze them based on core advantages and application effects, providing a reference for industrial sludge treatment.
Industrial sludge, due to its complex composition and high moisture content, often fails to achieve the desired treatment effect with traditional dehydration methods. Selecting the appropriate dehydration agent is the key to improving the dehydration efficiency and reducing the treatment cost. Sludge enhancer, as a new type of sludge conditioner, demonstrates significant advantages in the deep dehydration of industrial sludge.
1. Common types of chemicals used for deep dewatering of industrial sludge
Inorganic coagulants
Characteristics: Such as polyaluminium chloride (PAC), aluminum sulfate, etc., are inexpensive, but require a large dosage, which can easily cause secondary pollution.
Applicable scenarios: Suitable for situations where the requirement for dehydration effect is not high.
Organic polymer flocculant
Characteristics: For example, polyacrylamide (PAM), has a good dehydration effect, but it is expensive and sensitive to the properties of the sludge.
Applicable scenarios: Suitable for sludge with high organic matter content.
Composite Medication
Feature: It combines the advantages of inorganic and organic agents, but the formula is complex and requires targeted adjustments.
Applicable scenarios: Suitable for industrial sludge with complex components.
New types of sludge conditioning agents (such as sludge enhancers)
Features: Efficient dehydration, wide adaptability, environmentally friendly and cost-effective.
Applicable scenarios: Suitable for various industrial sludges, especially showing significant effects on sludges that are difficult to dehydrate.
2. Core advantages of sludge enhancer
High-efficiency dewatering performance
The sludge enhancer can significantly reduce the moisture content of the sludge, and the moisture content of the sludge cake can be lowered to below 60%, which is superior to traditional chemicals.
Broad adaptability
It is effective for various industrial sludges such as those from chemical, dyeing, and paper industries, and there is no need to frequently adjust the formula.
Environmental protection features
No heavy metal residues, in line with environmental protection requirements, and reducing the risk of secondary pollution.
Economy
The dosage of the agent is small, the overall cost is lower than that of traditional agents, and it can also reduce the energy consumption of the equipment.
Easy to operate
The dosing method is flexible and can be directly used in conjunction with traditional dehydration equipment.
3. Application effect of sludge enhancer
Sludge cake moisture content: Can be reduced to below 60%, meeting the requirements for deep dewatering.
Dosage of the medicine: 30% - 50% less than that of traditional medicines.
Dehydration efficiency: Increased by 20% - 40%, shortens the dehydration cycle.
Equipment energy consumption: Reduced by 15% - 25%, resulting in lower operating costs.
4. Reasons for Choosing Sludge Enhancer
Leading Technology
The sludge enhancer adopts a unique formula design, providing efficient solutions to the key problems of industrial sludge.
Actual verification
It has been successfully applied in multiple industrial fields, and user feedback indicates stable dehydration effect and significant economic benefits.

5. Application Suggestions
Pilot Testing
It is recommended that enterprises conduct a small-scale trial first to determine the optimal dosage and process parameters.
Optimize the dosing point
Choose pre-dosing or post-dosing based on the nature of the sludge to achieve the best results.
Process collaboration
Combine with mechanical dehydration equipment (such as plate and frame filter presses, centrifuges, etc.) to further enhance the dehydration efficiency.
6. Conclusion
The selection of deep-dewatering agents for industrial sludge should take into account the characteristics of the sludge, treatment requirements, and cost-effectiveness. The sludge enhancer, with its efficient, environmentally friendly, and economical features, has become an ideal choice for industrial sludge treatment. It is recommended that enterprises, based on their own needs, conduct experiments to verify its applicability, in order to achieve the best dewatering effect and economic benefits.
