The application effect of sludge enhancer in the dewatering of papermaking sludge is significant, which is manifested in the following aspects:
First, deep dehydration effect
Sludge enhancer can effectively reduce the moisture content of sludge and achieve deep dehydration of sludge. This is mainly by changing the surface structure and properties of the sludge, destroying the colloidal structure and bacterial structure in the sludge, so that the sludge particles are easier to separate and dehydrate. Usually, the sludge enhancer can reduce the sludge moisture content from more than 90% to 40%~60%, greatly reducing the volume and weight of the sludge, and providing convenience for subsequent treatment.
Two, improve the dehydration efficiency
Sludge enhancer can not only reduce the moisture content of sludge, but also significantly improve the dewatering efficiency of sludge. By optimizing the dewatering performance of the sludge, the sludge synergist can shorten the dewatering time and reduce the running time and energy consumption of the dewatering equipment. In practical applications, some paper mills in the use of sludge synergists, sludge dehydration efficiency increased by more than 30%, or even higher.
Three, simplify the process
The application of sludge enhancer can also simplify the sludge treatment process. Because sludge synergists can improve the colloidal structure and viscosity of the sludge, some tedious pretreatment steps (such as long stirring, pH adjustment, etc.) can be simplified or omitted. This not only reduces the processing cost, but also improves the processing efficiency.
Four, reduce equipment maintenance costs
Sludge enhancer can improve the fluidity of sludge and reduce the wear and blockage of sludge to dewatering equipment. This helps to extend the service life of the dewatering equipment and reduce the maintenance cost of the equipment. At the same time, because the sludge booster is non-stick filter cloth, the frequency of replacing the filter cloth of the dewatering equipment is reduced, and the operating cost is further saved.
Five, 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. This will help achieve energy conservation, emission reduction and environmental protection. In addition, the sludge after deep dehydration is easier to follow-up treatment, such as incineration, brick making, composting, etc., so as to realize the resource utilization of the sludge.
In summary, the application effect of sludge enhancer in paper sludge dewatering is remarkable, with multiple advantages such as deep dewatering, improving dewatering efficiency, simplifying treatment process, reducing equipment maintenance costs and environmental benefits. Therefore, sludge enhancers have broad application prospects in the field of paper sludge treatment.
