This is a domestic reverse osmosis (RO) membrane offered in models 1812-50, 1812-75, 2012-100, and higher capacities, manufactured by HJC International Com. Ltd. in China. The 2G series membranes operate at a standard pressure of 60psi, with a salt rejection rate of 97.0% and flow rates ranging from 50 to 400 gallons per day (GPD). The effective membrane area varies by model, from 3.5 to 40 square feet.
The membranes are designed for household and light commercial water purification systems, using thin-film composite (TFC) technology for efficient contaminant removal. Typical operating temperatures range from 4°C to 45°C, with a standard pH tolerance of 3 to 10. The 3G series, also available, offers a higher salt rejection rate of 98%, suitable for applications requiring stricter water quality standards.
These RO membranes are commonly used in under-sink water filters, whole-house systems, and industrial pre-treatment units. Buyers typically source them in bulk for assembly into complete RO systems or as replacement components. The membranes are compatible with standard 1812, 2012, and 3012 housing dimensions, ensuring ease of integration into existing systems.

Before ordering, verify the exact model specifications, including salt rejection rate and flow rate, to ensure they match your system’s requirements. Request a sample membrane to test its performance with your feed water, as variations in water quality can affect output.
Discuss lead times for bulk orders, as RO membrane production may depend on demand and customization needs. Clarify Incoterms such as FOB or CIF Shanghai and confirm payment terms, which may include TT or LC. Packaging should be agreed upon to prevent damage during transit, as membranes are sensitive to physical stress.
Upon receipt, inspect the membranes for any visible defects and test their salt rejection rate using a TDS meter. Request a certificate of compliance for NSF/ANSI or other relevant standards. Ensure the membranes are stored in a cool, dry place to prevent degradation before installation.
