 东丽TORAY TM820V-400：8英寸高浓度海水淡化专用反渗透膜元件（8-Inch Special RO Membrane Element for High-Concentration Seawater Desalination）

中文：东丽TORAY TM820V-400是一款8英寸高浓度海水淡化专用反渗透膜元件，依托东丽集团近60年液体分离膜研发与制造经验，采用先进交联全芳香聚酰胺复合膜技术及精密卷制工艺打造，严格遵循ISO 9001质量体系标准生产[4]。该膜元件专为含盐量32000mg/L左右的高浓度海水淡化场景设计，具备世界一流的耐压能力与脱盐性能，核心优势在于高脱盐率、高脱硼率与高稳定性兼具[1]。其有效膜面积达400平方英尺（37平方米），搭配34mil宽给水流道，既实现高效产水，又大幅提升抗污染能力与化学清洗恢复性，凭借优异的耐高压特性，成为大型海水淡化项目及高盐废水处理的核心优选膜元件，广泛应用于各类高浓度盐水处理场景[1][2]。

英文：TORAY TM820V-400 is an 8-inch special reverse osmosis membrane element for high-concentration seawater desalination. Based on Toray Group’s nearly 60 years of experience in R&D and manufacturing of liquid separation membranes, it is built with advanced cross-linked fully aromatic polyamide composite membrane technology and precision spiral-wound technology, and strictly produced in accordance with ISO 9001 quality system standards [4]. Specifically designed for high-concentration seawater desalination scenarios with salt content around 32000mg/L, this membrane element has world-class pressure resistance and desalination performance, with core advantages of combining high salt rejection rate, high boron rejection rate and high stability [1]. It has an effective membrane area of 400 square feet (37 square meters) and is equipped with a 34mil wide feed water flow channel, which not only achieves high water production efficiency, but also greatly improves anti-fouling ability and chemical cleaning recoverability. With its excellent high-pressure resistance, it has become the core preferred membrane element for large-scale seawater desalination projects and high-salt wastewater treatment, and is widely used in various high-concentration brine treatment scenarios [1][2].
