Sludge enhancer can solve the problem of high sludge moisture content. The following is a detailed analysis of how sludge enhancers reduce sludge moisture content:
One. Mechanism of action of sludge synergists
Change the surface properties of the sludge particles: the sludge synergist can change the surface properties of the sludge particles, such as charge distribution and hydrophobicity, making it easier to aggregate and precipitate between the sludge particles, reducing the free water content in the sludge.
Damage the colloidal structure of sludge and microbial cells: sludge synergists can destroy the colloidal structure and microbial cell structure in the sludge, and release the bound water in the cell, which is often difficult to remove in the conventional dehydration process.
Form a more stable bond: The sludge synergist can form a more stable bond with the water molecules in the sludge, reducing the freedom of the water molecules and helping to separate more water from the sludge during the dehydration process.
Two. Application effect of sludge synergist
Significantly reduce the moisture content of sludge: sludge enhancer can reduce the moisture content of sludge to 40%~60%, and significantly improve the dehydration efficiency of sludge.
Improve solid content: After the use of sludge enhancer, the solid particles in the sludge are more likely to gather together, thereby increasing the solid content of the sludge.
Simplified pretreatment steps: sludge synergists can improve the colloidal structure and viscosity of the sludge, so that some tedious pretreatment steps (such as long stirring, adjusting pH value, etc.) can be simplified or omitted.
Shorten the dehydration cycle: The use of sludge enhancer with mechanical dehydration equipment (such as plate and frame filter press, belt filter press, etc.) can significantly improve the dehydration efficiency and shorten the dehydration cycle.
Reduce equipment maintenance costs: sludge synergists can improve the flow of sludge, reduce the wear and blockage of sludge to dewatering equipment, thus reducing the maintenance cost of equipment.
Precautions for the use of sludge synergists
Select the right synergist: The effectiveness of different types of sludge synergists in reducing sludge moisture content may vary. Therefore, in the selection of synergists, it is necessary to conduct tests and evaluations according to the specific properties and treatment requirements of the sludge to determine the best type and dosage of synergists.
Follow the operating procedures and safety standards: The use of sludge enhancers needs to follow certain operating procedures and safety standards to ensure the stability and safety of the treatment process.
Proper disposal of the treated sludge: For the treated sludge and synergist residues, proper disposal and management are required to avoid secondary pollution to the environment.
In summary, sludge enhancers have significant effects in reducing the moisture content of sludge, and are important auxiliary materials in the sludge treatment process. Through rational use of synergists, the dewatering efficiency and treatment effect of sludge can be significantly improved, contributing to environmental protection and resource recovery.
