中文：东丽TORAY TM820V-400针对性解决高浓度海水淡化中膜耐压不足、污堵频繁、运维成本高的核心痛点，采用全方位耐高压、耐污染构型设计，适配各类复杂高盐给水场景[1]。其34mil宽给水流道优化设计，可有效减少污染物沉积，提升水流扰动性，降低膜表面污堵速率，同时优异的膜片材质的化学稳定性，进一步减少有机物、胶体吸附，大幅延长清洗周期[1]。该膜元件具备宽泛的化学清洗pH范围（1~12），可快速有效去除各类膜污染沉积物，清洗后性能恢复性优异，能快速回归最佳运行状态[1]。此外，其进水自由氯浓度需控制在检测不到的范围，搭配规范预处理，可大幅提升系统运行安全性，减少膜损坏风险，从根本上降低运维成本与停机时间，延长膜元件整体使用寿命[1]。

英文：TORAY TM820V-400 specifically solves the core pain points of insufficient membrane pressure resistance, frequent fouling and high operation and maintenance costs in high-concentration seawater desalination, adopting a comprehensive high-pressure and anti-fouling configuration design to adapt to various complex high-salt water supply scenarios [1]. Its 34mil wide feed water flow channel optimized design can effectively reduce pollutant deposition, improve water flow disturbance, and reduce the fouling rate on the membrane surface. At the same time, the excellent chemical stability of the membrane material further reduces the adsorption of organic matter and colloids, greatly extending the cleaning cycle [1]. This membrane element has a wide chemical cleaning pH range (1~12), which can quickly and effectively remove various membrane fouling deposits, with excellent performance recoverability after cleaning, and can quickly return to the best operating state [1]. In addition, its inlet free chlorine concentration needs to be controlled at an undetectable range, and combined with standardized pretreatment, it can greatly improve the safety of system operation, reduce the risk of membrane damage, fundamentally reduce operation and maintenance costs and downtime, and extend the overall service life of the membrane element
