RO systems are one of our core products. As a one-stop manufacturer, we have imported two fully automated membrane winding lines from South Korea, with an annual production capacity exceeding one million units. We rigorously control the quality of raw materials (imported membranes, filter screens, glue, and Y-rings, etc.), all of which are NSF certified. All tests meet NSF 58 requirements, achieving high flow rates with maximum effective membrane area and maintaining a stable salt rejection rate of ≥95% even at high total dissolved solids (TDS) input. Membranes can be stored dry for long-term preservation and are 100% vacuum tested before shipment. Our production workshop is dust-free and maintains a constant temperature and humidity. Our membranes are wound using fully and semi-automatic machines, ensuring more uniform winding and excellent filtration results.
