Will unstable sludge inlet solid content affect dewatering performance badly?

Equipped with linked frequency conversion pressure adjustment system, it automatically adapts to fluctuating feed concentration by adjusting pressing pressure and screw speed in real time, keeping sludge cake dryness stable without frequent manual parameter tuning.

What is the solid capture rate after treatment? Is the suspended solid content high in filtrate?

The solid capture rate can reach 90%-98% under normal flocculation conditions, filtrate holds low suspended solids and can flow back to front biochemical tank directly without extra system load.

Does each machine come with installation instructions?

Every unit is supplied with paper and electronic installation drawings & operation manuals with complete commissioning steps.

What voltage specifications does the machine support?

Voltages such as 380V, 415V and 220V can be customized to match 50Hz or 60Hz power frequency in different countries.

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:Does the machine consume much water during operation?

Only a small amount of clean water is used for screen cleaning; it requires no massive flushing water with low water consumption.

Q:Will the machine produce loud noise and strong vibration?

Designed with low-speed high-torque drive, the unit has slight vibration and much lower noise than similar dewatering machines.

Q:Do we need workers to monitor the machine 24 hours a day?

With full sealing and overload protection, it can run automatically for 24 hours without on-site attendants.

Q:How long is the machine warranty period?

We provide one-year free warranty for the whole machine, including core parts like reducer and motor. Lifetime technical support and spare parts supply are available.

Q:How to solve material blockage fault?

The machine will stop automatically under overload. After shutdown, jog the screw reversely to clear residual materials for normal operation.
