Sea Water(SW) RO Membrane Sheet-Jiangsu Bangtec Huachuang Sci-tech Co., Ltd.

Sea Water(SW) RO Membrane Sheet

Seawater Desalination Membrane Sheet
Core positioning: "High desalination" diaphragm under extreme conditions, designed for high-salt seawater (TDS 30000~35000mg/L) to achieve "seawater into fresh water".

Key features:
Desalination rate is the core indicator (≥99.5%), which can reduce seawater TDS to below 500mg/L (in line with drinking water standards);
Extremely high mechanical strength: the support layer is made of high-strength non-woven fabric + polyester mesh, which can withstand high pressure of 5.5~8.0MPa and is resistant to salt corrosion (resistant to chloride ion penetration).
The water flux is low (20%~30% lower than that of the brackish water membrane), it needs to be driven by high pressure, and the energy consumption is high.
Scene adaptation: large-scale seawater desalination projects in coastal cities (such as Jubail, Saudi Arabia, Zhoushan, my country), fresh water preparation for ocean-going ships, and water supply for island residents.

Category Introduction

The RO Membrane Sheet is the core functional component of reverse osmosis technology, serving as a semi-permeable membrane material that achieves substance separation through the principle of selective permeation. Driven by pressure, it efficiently retains ions, organic matter, microorganisms, and other impurities in water while allowing only water molecules to pass through preferentially. This makes it a key element in water treatment and substance separation for purification, concentration, and refinement processes.
