AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company serving environmental-protection and water-treatment markets, with stated in-house R&D and manufacturing capabilities and broad customization options. It reports quality assurance, 100% finished-product inspection, and one quality inspector, but finished products are checked by packing staff and raw materials are not traceable. Service-management controls are weakly documented: there is no approved-supplier list, no written corrective/preventive-action records, and no written complaint-handling procedures. Export sales represent 71%–90% of total sales, and the supplier began exporting two years ago. It has no overseas showroom, overseas agents or branches, offline trade-show participation, or listed overseas service countries. Certification of supplier management systems is recorded as NIL. Financial records are indicated for multiple years, but no detailed financial results are provided. Customer cases are not supplied.

CertificationsCertification of supplier management systems is explicitly recorded as NIL. Therefore, the provided information does not demonstrate that the supplier holds relevant management-system certifications.

After-Sales capabilityThe supplier has no written procedures or records for corrective and preventive actions or customer complaint handling. It also reports no overseas agents or branches, no overseas showroom, and no overseas service countries, indicating limited documented and geographic after-sales support.

R&D capabilityThe supplier states that it has in-house R&D, new-material technology research, data-driven regional solutions, and environmental-protection technology activities. However, it explicitly reports no available SDK, so the evidence supports general R&D capability but not SDK-based development capability.

Customization capabilityThe supplier explicitly offers customized product development and lists full customization, customization from designs and samples, minor customization, and flexible customization. These statements provide direct evidence of broad customization services.

Product Q&A

Q:Is 1*400GPD better than 2*200GPD?

200GPD is better, there's less glue during production, better salt rejection rate and water flow.

Q:When to clean the membrane elements?

It is important to clean the membrane elements when any of the following conditions occur: 10-15% decrease in normalized permeate flow, 10-15% increase in normalized permeate total dissolved solids (TDS), 10-15% increase in normalized pressure drop between feed and reject.

Q:How to Solve RO Membrane Blockage?

1. Firstly, you need to determine if the membrane of the home RO System is really blocked. 2. Understand the water quality in the region and see if the main components of scale are mainly composed of calcium and magnesium salts. 3. Dispense the syrup (10% hydrochloric acid) or the diluted detergent (descaling detergent on the market) and the special RO membrane cleaning agent according to the composition of the scale, and place the RO membrane therein for 24 hours. 4. Next, rinse the RO membrane

Q:Why the RO membrane is blockage after one to two months?

1. raw water with high salt content, too many scales. 2. the content of organic matter in the water exceeds the standard, RO membrane is fouled and plugged 3. high RO film recovery rate 4. the purifier is not equipped with flushing function. After long-term use, high-concentration brine is deposited in the RO membrane shell.

Q:How to install the flow restrictor?

Install in the drain line that dumps waste water into the sink. Find the line hooked up to your sink drain and splice the flow restrictor in. Follow the arrow direction. Ensure tubing is cut squared and straight, then insert straight and all the way into the connector.
