Sludge conditioner is a chemical agent that can change the surface structure of the sludge, reduce the solid surface load of the sludge, reduce the specific surface area of the sludge, and destroy the bacterial structure, and plays an important role in the dewatering application of paper making sludge. The following is a detailed analysis of the application of sludge conditioner in the dewatering of paper making sludge:
Principle of action of sludge conditioner
Sludge conditioner contains water purification agent, organic polymer, sludge stripping agent, sludge surface treatment agent, wall breaking agent degreaser, sludge surface structure modifier and other components. Through synergistic action, these components change the surface properties of the sludge, reduce the specific surface area of the sludge, destroy the cell wall and cell membrane, release intracellular water, and then remove free water, bound water, capillary water and intracellular water in most biochemical sludge.
Application effect of sludge conditioner in dewatering of paper making sludge
Improve sludge dewatering performance: paper sludge conditioner can effectively improve the dewatering performance of sludge, reduce the moisture content of sludge, and improve the dewatering efficiency. This is mainly because the conditioner can destroy the colloidal structure in the sludge, making it easier for the sludge particles to separate and dehydrate.
Improve production efficiency: After the use of sludge conditioner, the production efficiency of sludge dewatering equipment can be significantly improved, the treatment time is reduced, and the energy consumption is reduced.
Reduce treatment costs: By improving the dewatering performance of sludge, the energy consumption and subsequent treatment costs of sludge treatment can be reduced, thus reducing the overall treatment cost.
Improve the stability of sludge: sludge conditioner can also improve the stability of sludge, prevent secondary pollution, and is conducive to the subsequent treatment and disposal of sludge.
Selection and use of sludge conditioner
Selection principle: According to the nature of sludge and the type of dewatering equipment, choose the appropriate type and dosage of sludge conditioner. Generally speaking, for the sludge with higher moisture content, the conditioner with better dehydration effect should be selected; For the sludge containing a large amount of fiber material, the conditioner that can destroy the fiber structure should be selected.
Method of use: The sludge conditioner is usually uniformly added to the sludge by dosing equipment, and is fully mixed with the sludge. After mixing, the dewatering property of the sludge will be significantly improved.
Four, sludge conditioner in paper sludge dewatering precautions
Avoid excessive use: Excessive use of sludge conditioner may lead to reduced sludge treatment effect, and even cause corrosion or blockage of equipment.
Pay attention to equipment maintenance: In the process of using sludge conditioner, the dewatering equipment should be regularly checked and maintained to ensure its normal operation and long-term use.
Pay attention to environmental protection requirements: When dealing with papermaking sludge, you should pay attention to local environmental protection requirements and emission standards to ensure that the treated sludge meets the relevant requirements.
In summary, the sludge conditioner has significant effects and advantages in the application of paper making sludge dewatering. Reasonable selection and use of sludge conditioner can significantly improve the dewatering performance of sludge, increase production efficiency, reduce treatment costs, and facilitate the subsequent treatment and disposal of sludge.
