英文：TORAY TM720D-400 reverse osmosis membrane element strictly implements Toray’s global unified quality standards. From membrane material formulation, film formation process to element winding, high-precision automatic production lines are adopted to ensure the performance consistency and reliability of each membrane element. As a 400 square foot class 8-inch brackish water membrane, this product has stable water production capacity under standard test conditions (2000ppm NaCl solution, 225psi pressure, 25℃ temperature, pH 8, 15% recovery rate), which can meet the continuous operation needs of large and medium-sized water treatment systems. Its membrane sheet has excellent anti-compaction performance, with small flux attenuation during long-term operation, effectively reducing the system operation cost. The element adopts high-strength FRP shell and central tube structure, with strong impact resistance and deformation resistance, convenient installation and replacement, and can adapt to various standard 8-inch pressure vessels. Each membrane element undergoes strict factory performance testing to ensure that the flux, salt rejection, tightness and structural strength fully meet the standards. Relying on strict manufacturing processes and full-process quality control, it has a stable reputation in the global industrial market.
