SINOMEMB RO Flat Sheet Membrane represents HID's advanced manufacturing capabilities in water filtration technology. Since 2014, we've expanded to three fully automated production lines with a daily output of 30,000 square meters, ensuring consistent quality control from raw sheets to finished membrane elements.

• High rejection rate for superior filtration performance
• Extended service life for cost-effective operation
• Consistent rejection with maintained nominal flux
• Sanitation-certified elements for safe water purification
• Rigorous in-house inspection and testing protocols

Reverse osmosis represents the most advanced level of water filtration available. Our RO membrane effectively blocks dissolved salts, inorganic molecules, and organic compounds with molecular weights above 100, while allowing water molecules to pass freely.

Typical salt rejection rates range from 95% to over 98%, making our membranes ideal for:

• Drinking water desalination (seawater and brackish water)
• Wastewater recovery systems
• Food and beverage processing
• Biomedical applications
• Residential and industrial water purification

With two production bases and a dedicated mechanical design team, HID has vertically integrated our supply chain to include spacers, O-rings, and gaskets. Our SINOMEMB™ Sheet technology has significantly enhanced our RO membrane manufacturing expertise, enabling us to deliver superior quality products for global water safety applications.
