Does the machine require embedded foundation or shockproof base?

Heavy shockproof concrete foundation is not required; flat hardened ground is enough for installation.

What are the main wearing parts? How often do they need replacement?

Main wearing parts are moving rings and seals. Moving rings last 3~5 years under normal conditions, seals need replacement every half a year to one year.

How long is the machine warranty? Which parts are covered?

Standard one-year warranty. Man-made damage and consumable wearing parts are excluded.

How to clean residual sludge inside after long-time shutdown?

Built-in cleaning pipeline connects to clean water to flush internal sludge residue without full disassembly.

How about after-sales service when the machine breaks down?

Online remote troubleshooting support; on-site engineer maintenance will be arranged if online guidance fails.

How to choose between screw press and decanter centrifuge?

Screw press is preferred for oily, fibrous and low-concentration sludge; decanter centrifuge fits large capacity, hard particle sludge and three-phase separation.

What are the differences between screw press and plate frame filter press?

Screw press runs continuously automatically without filter cloth; plate frame works intermittently with regular filter cloth replacement, yet achieves drier sludge cake.

Key features

Self-cleaning moving and fixed ring structure, effectively preventing clogging when treating high-viscosity, oily and fibrous sludge.

Integrated thickening and dewatering design; low-concentration sludge can be fed directly without an independent thickening tank.

Capable of 24-hour continuous operation as well as intermittent start-stop; frequent startup and shutdown will not damage the equipment.

Equipped with PLC automatic control, interlocked with dosing system to support unattended operation.

Extremely low power consumption; no continuous high-pressure flushing required, saving water consumption greatly.

Sludge flocs are protected from breaking, resulting in lower consumption of PAM flocculant.

Compact structure with small footprint, low civil construction cost and fast installation & commissioning. Simple construction without sophisticated components such as differential gears, enabling eas

Long service life of wearing parts, low maintenance frequency and convenient disassembly & inspection.

Suitable for various sludge including municipal sludge, oily kitchen sludge, papermaking sludge, printing & dyeing sludge, chemical sludge, food sludge and river silt, applicable to both thin and thic

AI-Powered supplier vetting

SummaryThe supplier specializes in water treatment technology and equipment, offering solutions for water-quality and industrial applications. It reports ISO9001 certification, OEM and ODM services, flexible customization, four R&D engineers, two patents, an available SDK, and recent new-product development. Documented procedures exist for supplier assessment, corrective and preventive actions, customer complaints, and R&D documentation. However, finished products are checked by packing staff, and the supplier reports no quality assurance, overseas showroom, overseas agents or branches, offline trade-show participation, or overseas-service coverage. Export experience is stated as one year. Financial information is insufficient for judging credibility.

Supplier typeThe company specializes in water treatment technology and equipment and provides solutions for water-quality issues and industrial applications. This supports classification as a specialized water-treatment technology and equipment supplier.

CertificationsThe supplier states that it is certified by authoritative ISO systems, and the company overview specifically identifies ISO9001 certification. The provided information supports certification holding, although no certificate number, scope, or validity period is given.

R&D capabilityThe supplier reports a national science and technology progress award, an available SDK, four R&D engineers, two patents, R&D audit documentation, recent new-product development, and stated investment in technological innovation. These are explicit indicators of innovation activity and supporting infrastructure.

Production capacityThe supplier reports one-month average lead times in both peak and off-season, written procedures and records for supplier-service assessment, and documented corrective-action and complaint procedures. However, finished products are checked by packing staff and the supplier explicitly reports no quality assurance, preventing a positive assessment of overall production capability.

Customization capabilityThe supplier offers customization from samples, designs, full customization, minor customization, and flexible customization. Its R&D engineers are responsible for flexible customization, and ODM service and recent product development are also reported, demonstrating broad customization support.

Client casesThe supplier explicitly reports providing OEM services for popular brands, which is evidence of at least one category of brand-customer engagement. No customer names, project details, quantities, or independently verifiable case studies are provided.

Product Q&A

Q:How to confirm which model capacity I need?

Please provide daily sludge output, sludge moisture content and sludge type. We can calculate the matching model, and lab test with your sludge sample is available.

Q:What is the moisture content of sludge after dewatering?

Conventional municipal sludge can reach 75%~82% moisture; oily kitchen and chemical sludge can hit 70%~78% depending on chemical dosing.

Q:Will the machine rust when treating sludge from acid and alkaline wastewater?

Standard full 304 stainless steel; 316L stainless steel is optional for severe corrosive conditions to resist acid, alkali and salt.

Q:Is the spiral blade easy to wear out? Can it handle sludge with lots of sand?

Standard spiral for normal conditions; hard alloy surfacing wear-resistant spiral can be customized for sludge with plenty of sediment.

Q:What auxiliary equipment is required for normal operation?

Sludge feed pump, PAM dosing & mixing tank, chemical transfer pump are normally matched. Complete integrated package supply is available.
