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:Can your NF membranes completely replace DOW FILMTEC or Synder elements without system modifications?

Yes. Our NF elements share identical physical dimensions and vessel compatibility with models like NF90, NF270, and NFX. You can do a direct drop-in replacement without changing your existing piping or pressure vessels.

Q:What is the difference between your NF1, NF2, and NF3 series for water softening?

Our NF1 (replaces NF90) offers the highest salt and organic rejection. NF3 (replaces NF270) provides a higher water flux and partial softening, making it ideal for clean groundwater. NF2 balances high rejection with specific organic removal.

Q:Do you provide small-scale membranes for pilot testing before bulk orders?

Yes, we manufacture the 1812 size NF membrane specifically for laboratory and pilot-scale testing. This allows you to verify exact flux rates, cross-flow performance, and rejection efficiency using your actual feed water.

Q:How do your NF membranes perform in food processing and dairy applications?

Our NF5 series features excellent magnesium sulfate and lactose rejection. It is widely used in the dairy industry for the simultaneous concentration and partial demineralization (desalting) of whey and milk streams.
