Is the operation of this screw press automatic?

Yes, it is fully automatic. The device can be set to operate automatically via the electric control cabinet, requiring no filter clothes or filter pores that are prone to blocking.

What is the final moisture content of the dewatered sludge?

The sludge after dewatering and separation is stable in the moisture range of 70-85%, significantly reducing the workload for subsequent deep dewatering processes.

What are the delivery lead times for this equipment?

The lead time depends on the season. During peak season, it takes one month. During the off-season, delivery is within 15 workdays.

Product Q&A

Q:Does the screw press require frequent maintenance or cleaning?

No, the machine features a self-cleaning design where moving and fixed rings rotate to prevent blockage. It handles oily sludge without trouble and does not require large quantities of flushing water.

Q:What is the power consumption of this sludge dehydrator?

The average unit power consumption is only 0.1-0.01kwh/kg-DS. This is approximately 1/8 of a Belt Filter Press and 1/20 of a Centrifuge, greatly reducing running costs.

Q:Can this equipment be customized for specific capacities?

Yes, the treating capacity can be customized from 0.1 to 300 M3/H. The shaft quantity can also be adjusted between 1 and 4 units to meet specific requirements.

Q:What types of sludge can this machine process?

It is suitable for various types of sludge including municipal sewage, food wastewater, slaughterhouse waste, printing and dyeing, oil chemical industry, paper making, leather, and pharmacy sludge.

Q:How does the machine prevent clogging during operation?

The movement of the moving rings against the fixed rings continuously cleans the gaps between them. This self-cleaning mechanism prevents blockage and allows for easy water separation.
