What is the service life of the equipment?

Under normal operation and regular maintenance, the whole machine can work for 10-15 years. The wearing parts such as disc rings and screw shaft can be used for 3-5 years, and spare parts are available for supply.

Can you customize the machine model?

Yes. We provide different models from small lab type to large capacity type. Customization is available according to your sludge volume, sludge property and site condition.

What is the power consumption?

Low energy consumption. The main motor runs at low speed, power consumption is much lower than filter press and belt sludge dewatering machine.

AI-Powered supplier vetting

SummaryDZ presents strong engineering, customization, and production evidence. It has an R&D team, experienced workers, five production lines, stated annual filter-press output, advanced production and detection equipment, and a quality system covering warehousing, processing, and assembly. The supplier supports OEM, ODM, SDK availability, and multiple customization modes, and reports 17 years of export experience with 21%–30% of sales from exports. However, its certification status is listed as NIL, and service-management controls are weak: no written procedures or records were reported for supplier-service assessment, corrective actions, or complaint handling, and no approved-supplier list is maintained. Financial information is referenced for recent years, but the provided slices do not disclose enough non-financial evidence to assess financial credibility. Customer references are limited to an unquantified statement of OEM service for well-known brands.

Supplier typeDZ is presented as a production-oriented manufacturer focused on filtration solutions, particularly filter presses, with five production lines, advanced production equipment, and stated filter-press output. Its registered scope also includes stainless-steel processing, industrial robot manufacturing, engineering management, and technical services, indicating a diversified industrial supplier profile.

CertificationsThe supplier management-system certification status is explicitly listed as NIL. This is a stated absence of certification evidence for this field.

R&D capabilityDZ reports an R&D team, eight years of total R&D-engineer experience, new products during the past year, ODM service, and an available SDK. These are explicit indicators of active product-development and technical capability.

Production capacityThe supplier operates five production lines and reports filter-press output of 9,500 sets plus 4,500 other units, supported by shearing, bending, and cutting machinery. Its production base has advanced lines and detection equipment, while a quality system is stated to monitor warehousing, processing, and assembly.

Customization capabilityDZ explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. The same range is recorded in both its R&D and design-capability information, providing direct evidence of broad customization coverage.

Product Q&A

Q:What is a multi-disc screw dewatering machine?

It is a solid-liquid separation sludge dewatering equipment with stacked fixed and moving rings and screw shaft structure. Stainless steel material, low-speed operation, self-cleaning function, no clogging, widely used for sludge dewatering in various industries.

Q:What types of sludge can this machine handle?

It can treat municipal sewage sludge, river/lake dredging sludge, food wastewater sludge, chemical sludge, stone cutting slurry, printing & dyeing sludge, landfill leachate, aquaculture sludge, tunnel boring mud, papermaking sludge and other organic & partial inorganic sludge.

Q:What is the moisture content of discharged sludge cake?

Normally, the moisture of dewatered sludge cake ranges from 75%~85%. The final value depends on sludge property, flocculant type and dosing amount.

Q:Does the multi-disc screw press get clogged easily?

No. The relative movement between fixed rings and moving rings realizes continuous self-cleaning. It avoids filter cloth blockage problem compared with filter press or belt dewatering machine, suitable for high-viscosity sludge.

Q:What are the advantages of your screw dewatering machine?

Low power consumption, automatic continuous running, simple maintenance, small footprint, fully stainless steel main body, low noise, can run 24 hours continuously.
