AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company offering membrane filtration products and related components. It holds an ISO9001:2015 certificate and reports five quality assurance and quality control inspectors, with finished-product inspections conducted by random sampling under documented and consistently followed instructions. Customization, ODM, and OEM services are available, but the supplier is not identified as a professional technical supplier, does not provide 3D software design services, and reported no new products in the past year. Service-management documentation is incomplete: records exist for service capability assessment, but written procedures or records are absent for corrective actions and complaint handling. Overseas service infrastructure is limited, with no overseas warehouse, showroom, agent, or branch. Financial information is present only as year labels, so financial credibility cannot be assessed.

CertificationsThe supplier reports an ISO9001:2015 certificate in both supplier-management certification and sustainable-development management information. The slices do not provide certificate scope, validity, or verification details, but they do explicitly evidence certification holding.

After-Sales capabilityService capability has relevant records and an approved-supplier list with some supplier names, but there are no written procedures or records for corrective and preventive actions or effective customer-complaint handling. Overseas support is also limited because the supplier has no overseas warehouse, showroom, agent, or branch, although it has attended an offline trade show.

R&D capabilityThe supplier does not provide 3D software design services, has no available SDK, and reported no new products during the past year. It does offer ODM services and OEM services for popular brands, but the evidence does not demonstrate recent product innovation or technical R&D strength.

Customization capabilityThe supplier explicitly offers customization from designs, full customization, minor customization, and flexible customization. It also provides ODM and OEM services, which supports a demonstrated ability to handle customized requirements.

Product Q&A

Q:What is the maximum operating pressure of your ST module

Our ST module can operate up to 120 bar, making it suitable for high pressure seawater desalination and wastewater concentration applications

Q:How does your special feed spacer reduce fouling

The ladder type spacer contacts the membrane only at the edges, which minimizes flow resistance and greatly reduces fouling buildup compared to standard spiral wound elements

Q:Can your ST module replace Nanostone or Rochem products

Yes our STRO and STNF modules are direct cross replacements for Nanostone and Rochem high pressure membrane elements

Q:What is the difference between STRO and STNF

STRO uses reverse osmosis membrane for high salt rejection above 98 percent while STNF uses nanofiltration membrane for selective removal of divalent ions and organics

Q:What applications are suitable for your ST module

Typical applications include seawater desalination, industrial wastewater treatment, landfill leachate, RO concentrate treatment, and zero liquid discharge systems
