FilmTec BW30-400 RO Membrane is a high-performance brackish water reverse osmosis membrane designed for industrial water treatment systems.
With 400 ft² active membrane area, 10,500 GPD flow capacity, and up to 99.5% stabilized salt rejection, it delivers reliable purification performance.
Ideal for industrial RO plants, water purification systems, commercial water treatment, and brackish water applications.
Product Overview
FilmTec BW30-400 RO Membrane for Industrial Water Treatment
The FilmTec BW30-400 RO Membrane is a high-rejection brackish water reverse osmosis element designed for applications where high-quality permeate and reliable productivity are required. The BW30-400 uses a polyamide thin-film composite membrane in a spiral-wound element configuration.
With an active membrane area of 400 ft² (37 m²), the FilmTec BW30-400 provides a high surface-area solution for industrial RO systems. Under the manufacturer’s standard test conditions, the element has a nominal permeate flow of 10,500 GPD (40 m³/day) and typical stabilized salt rejection of 99.5%.
The FilmTec BW30-400 RO Membrane is suitable for brackish water reverse osmosis systems used in industrial water purification, water treatment, and other applications requiring effective dissolved-salt removal. DuPont describes FilmTec RO elements as spiral-wound thin-film composite polyamide membranes used across consumer, commercial, municipal, and industrial water treatment systems.
