Sludge enhancer as a new choice of paper sludge dewatering, has significant advantages and application effects. The following is a detailed analysis of the sludge synergist in the dewatering of papermaking sludge:
Principle of action of sludge synergist
Sludge enhancer is a chemical agent specially used to improve sludge dewatering performance, and its main components may include inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent, etc. These components work together to change the surface structure and properties of the sludge, reduce the surface load and specific surface area of the sludge solids, destroy the colloidal structure and bacterial structure in the sludge, and make the sludge particles easier to separate and dehydrate.
Two. Application advantages of sludge synergists
Improve dewatering efficiency: sludge synergists can significantly improve the dewatering efficiency of sludge and shorten the dewatering time, thus reducing the running time and energy consumption of dewatering equipment.
Reduce water 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 and reducing the water content. This helps to reduce the sludge volume for subsequent transport, storage and disposal.
Simplified treatment process: Because sludge synergists can improve the colloidal structure and viscosity of the sludge, some tedious pretreatment steps (such as long stirring, adjusting pH value, etc.) can be simplified or omitted.
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.
Environmental benefits: After the use of sludge enhancer, the moisture content of the dehydrated sludge is reduced, which reduces the discharge of harmful substances in the sludge, and helps to achieve energy conservation and emission reduction and environmental protection.
Three. Application cases of sludge enhancer in papermaking sludge
In the paper industry, sludge enhancers have been widely used in sludge dewatering treatment. For example, after the introduction of sludge synergist in a paper mill, the dewatering efficiency of the sludge has been significantly improved, and the water content of the dehydrated mud cake has been reduced from the original high level to a lower level. This not only improves the sludge treatment efficiency, but also reduces the treatment cost, and brings significant economic benefits to the operation of the paper mill.
Four, use precautions
Select the right sludge enhancer: Select the right sludge enhancer according to the nature of the sludge and treatment requirements. Different sludge synergists have different chemical composition and mechanism of action, so it is necessary to choose according to the specific situation.
Control dosage: The dosage of sludge enhancer should be adjusted according to the nature of the sludge and the performance of the treatment equipment. Too much or too little dosage may affect the treatment effect and economy.
Monitoring treatment effect: In the process of use, the dewatering effect and water content of the sludge should be regularly monitored to ensure the effectiveness of the sludge synergist.
Pay attention to environmental protection requirements: when selecting and using sludge enhancers, relevant environmental regulations and standards should be complied with to ensure that the treated sludge meets environmental protection requirements.
In summary, as a new choice for dewatering paper sludge, sludge enhancer has significant advantages and application effects. Reasonable selection and use of sludge enhancers can bring significant economic and environmental benefits to paper mills.
