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.

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.
