The Toray TML20D-400 8040 is an 8" × 40" brackish water RO membrane designed for efficient dissolved-salt removal and reliable performance in commercial, industrial, and water-treatment applications.
The Toray TML20D-400 8040 is a high-performance brackish water reverse osmosis (BWRO) membrane designed for efficient removal of dissolved salts, minerals, and other contaminants from brackish and industrial water sources. It features a spiral-wound thin-film composite membrane construction for reliable filtration and consistent permeate quality. With a standard 8040 configuration (8 × 40 inches), the TML20D-400 is suitable for commercial and industrial RO systems requiring dependable membrane performance and high-quality treated water. Its robust construction makes it suitable for continuous operation when the RO system is properly designed and appropriate pretreatment is provided. The membrane is designed for applications including industrial water treatment, municipal water purification, process-water production, groundwater treatment, and water-reuse systems. Proper pretreatment helps control fouling, scaling, and particulate loading, thereby supporting membrane service life and stable operating performance. Key Benefits Standard 8040 (8" × 40") membrane configuration Designed for brackish water RO applications Spiral-wound membrane element design Thin-film composite membrane technology Effective dissolved-salt and contaminant removal Suitable for industrial and commercial RO systems Consistent permeate quality when operated within recommended conditions Suitable for properly pretreated feed water Applicable to water purification and water-reuse systems Typical Applications Brackish water reverse osmosis plants Industrial RO water treatment Commercial RO systems Municipal water treatment Groundwater purification Process-water production Industrial water reuse Boiler-feed water treatment High-TDS water treatment Note: Actual membrane capacity and salt-rejection performance depend on feed-water quality, temperature, operating pressure, recovery, pretreatment, and system configuration. Always verify the current manufacturer's datasheet before finalizing system design or product specifications.
