Apoaqua - Model ApoBlu-SHS -Screw Press Dewatering Device

ApoBlu-SHS series oem screw press dewatering device is a high-efficiency lime sludge processing equipment. Whether it is fresh sludge or sludge digested from urban wastewater treatment, it can work stably and efficiently.

In addition to this, we also provide total solutions for lime sludge. It has the integrated processing functions of sludge dehydration and sludge concentration and dehydration.

• Fully enclosed operation, the site is clean and pollution-free.
• The consumption of flocculant and cleaning water is small, and the daily operation cost is low.
• The equipment layout is compact and covers a small area, which can significantly reduce land acquisition and infrastructure investment.

The significance of lime sludge dehydration

Lime sludge is a kind of sludge with high water content and viscosity. If it is not treated, it will cause great pollution to the environment. Therefore, the dehydration effect of lime sludge is to reduce its moisture content, thereby achieving the purpose of reducing environmental pollution.

After lime sludge is dehydrated, the following effects can be achieved:

• Reduce the volume of lime sludge to facilitate transportation and processing.
• Reduce the moisture content of lime sludge and increase the solid content of lime sludge.
• After dehydration, the lime sludge will form a pebble shape, which can be easily burned or landfilled.

Significance to the environmental protection industry

Lime sludge dehydration is a necessary step for sewage treatment at construction sites, domestic sewage treatment plants and other places. It helps protect the environment and reduce pollution. Wastewater discharge can be reduced by dewatering lime sludge. Improve resource utilization and reduce environmental pollution. At the same time, it can also reduce processing costs and shorten processing time, thereby improving processing efficiency.

Moreover, lime sludge has reuse value. After dehydration treatment, solid waste is formed, which can be used in fields such as construction and landscaping for recycling and reuse.

To sum up, the main function of lime sludge dehydration is to reduce its moisture content and achieve the purpose of reducing environmental pollution. Lime sludge dehydration is of great significance in the environmental protection industry. Not only can it protect the environment, but it can also improve data utilization and reduce environmental pollution. Therefore, dehydration of lime sludge is very necessary in the sewage treatment process.

How to Dewater Lime Sludge

• Concentration stage. Lime sludge enters the sludge dewatering machine through the feed inlet. As the screw shaft rotates, the lime sludge is gradually pushed into the interior of the machine. During this process, multiple fixed rings around the spiral axis move relative to each other. Under the action of gravity, water is filtered out from the gap of the moving fixed ring to achieve rapid concentration.
• Dehydration stage. The concentrated lime sludge continues to be pushed to the sludge outlet with the rotation of the screw shaft. As the pitch of the spiral shaft gradually becomes smaller, the gap between the rings also becomes smaller and smaller. This causes the water in the sludge to be squeezed out. Under the action of the back pressure plate at the outlet, the internal pressure gradually increases. The water in the sludge is further squeezed out to achieve continuous dehydration.
• Self-cleaning stage. The rotation of the spiral shaft drives the swimming ring to rotate continuously. The movement between the fixed ring and the moving ring enables a continuous self-cleaning process. This design cleverly avoids the common clogging problem of traditional dehydrators.

In addition, the screw auger of the ApoBlu-SHS screw press dewatering is driven by a variable frequency motor. By adjusting the speed of the motor, the mud processing volume can be controlled to achieve continuous operation at different output levels. The equipment has low noise during operation and requires little maintenance work. Compared with the plate and frame dehydrator, it realizes continuous operation and is easy to operate.
