The goal of 60% moisture content of papermaking sludge can be achieved through reasonable sludge treatment methods and the selection of appropriate sludge dewatering equipment. The following is the relevant analysis of paper sludge dewatering to 60% moisture content:

Current water content of papermaking sludge

The moisture content of paper sludge is usually between 50% and 80%, and this range varies according to different methods and equipment in the sludge treatment process.

Feasibility of achieving 60% moisture content

Sludge mechanical dewatering method:

By plate and frame filter press, belt filter press, diaphragm filter press, sludge drying machine and other dewatering equipment for mechanical pressing and drying.

The dewatering effect of different equipment is different, such as the belt filter press can usually dehydrate the paper sludge to more than 80% moisture content, and the high pressure sludge press dryer can treat the paper sludge once to less than 50% moisture content. Therefore, choosing the right sludge dewatering equipment is the key to achieve 60% moisture content.

Sludge granulation method:

The sludge is rolled into clay pellets by pelleting machine and further dehydrated to form large dense clay pellets.

However, the sludge moisture content of this method is usually above 70%, and further dehydration treatment may be required to reach 60% moisture content.

Natural drying method:

Put the sludge in the sludge drying field, and reduce the moisture content by infiltration and evaporation.

However, this method takes a long time and is greatly affected by weather conditions, which may be difficult to achieve a stable 60% moisture content.

Proposal to achieve 60% moisture content

Select the right sludge dewatering equipment:

According to the nature of sludge and dewatering requirements, choose efficient sludge dewatering equipment, such as high pressure sludge press dryer.

Optimize the use of sludge conditioner:

Select the appropriate sludge conditioner to improve the dewatering performance of sludge and improve the dewatering efficiency.

Strengthen the monitoring and management of sludge treatment process:

Real-time monitoring of the sludge treatment process to ensure the stable operation of all links, timely discovery and solution of problems.

Consider the resource utilization of sludge:

While reducing the moisture content of the sludge, the resource utilization of the sludge can be considered, such as the sludge is used for the production of cement, brick and other building materials, to achieve the reduction, harmlessness and resource of the sludge.

In summary, through reasonable sludge treatment methods and the selection of appropriate sludge dewatering equipment, the moisture content of papermaking sludge can be reduced to less than 60%. At the same time, strengthening the monitoring and management of the sludge treatment process, as well as considering the resource utilization of sludge, is also an important guarantee to achieve this goal.
