E-MEM® BW-4040 Brackish Water RO Membrane

High-Efficiency RO Membrane for Industrial & Commercial Water Purification

The E-MEM® BW-4040 Brackish Water Reverse Osmosis (RO) Membrane, developed by Hangzhou E-MEM Environmental Technology Co., Ltd., is an advanced aromatic polyamide composite membrane designed for desalting brackish water. With low operating pressure, high flux, and high salt rejection, it ensures optimal purification efficiency while maintaining long service life.

This high-performance RO membrane effectively removes dissolved salts, TOC, silica (SiO₂), and other contaminants, making it ideal for industrial pure water applications, power plant boiler feedwater, and high-purity water preparation for electronics and power industries.

Key Features & Benefits

✔ High Salt Rejection Efficiency – Removes up to 99.5% of dissolved salts
✔ Low Operating Pressure – Reduces energy consumption & operational costs
✔ High Flow Rate – Produces up to 2,400 GPD (9.1 m³/day) of purified water
✔ Superior Contaminant Removal – Eliminates TOC, silica, and organic impurities
✔ Ideal for Industrial & Brackish Water Treatment – Suitable for municipal, surface, and groundwater purification
