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 choose between rotary bar screen and internally-fed fine screen?

Rotary bar screen is suitable for coarse removal and large impurities. Internally-fed fine screen works better for fine particles, hair, fiber and MBR pre-treatment.

Q:What material options are available?

Frame: carbon steel with anti-corrosion coating or SS304. Wetted parts standard SS304; SS316L optional for corrosive wastewater.

Q:Can dimensions be customized?

Yes. Channel width, diving depth, installation angle and screen gap can be customized according to civil drawing.

Q:What control modes are available?

Manual & timer control as standard. Water level differential control optional, compatible with central PLC remote control.

Q:Is the machine easy to be blocked or wrapped by fibers?

Rotary screen adopts self-cleaning rake teeth. Internally-fed screen is equipped with high-pressure spray washing system to reduce fiber blockage.
