 东丽TORAY TMG20D-440：高脱盐率与高产水量，筑牢水质安全防线（High Salt Rejection and High Water Production, Building a Solid Line of Defense for Water Quality Safety）

中文：东丽TORAY TMG20D-440以高脱盐、高产水、稳通量为核心竞争力，是超低压苦咸水净化系统的标杆产品。该膜元件标准脱盐率可达99.7%，最低脱盐率不低于99.5%，在标准测试条件下（2000mg/L NaCl溶液、150psi（1.03MPa）压力、25℃温度、pH7、15%回收率），可稳定产出13300gpd（50.3m³/d）的产水量，最小透过水量达11200gpd（42.4m³/d），产水水质完全符合各类工业高纯水及市政饮用水标准[1][6]。膜片采用优化的分子结构设计，可大幅减少细菌、微生物在膜表面的吸附，有效降低污堵风险，同时优化的膜结构的设计，确保在长期运行过程中通量衰减小，始终保持稳定的产水效率，为电子、化工、电力、食品饮料等对水质要求严苛的行业筑牢水质安全防线[3][5]。

英文：TORAY TMG20D-440 takes high salt rejection, high water production and stable flux as its core competitiveness, and is a benchmark product for ultra-low pressure brackish water purification systems. The standard salt rejection rate of this membrane element can reach 99.7%, and the minimum salt rejection rate is not less than 99.5%. Under standard test conditions (2000mg/L NaCl solution, 150psi (1.03MPa) pressure, 25℃ temperature, pH7, 15% recovery rate), it can stably produce 13300gpd (50.3m³/d) of water, and the minimum permeate flow rate is 11200gpd (42.4m³/d). The produced water quality fully meets various industrial high-purity water and municipal drinking water standards [1][6]. The membrane sheet adopts an optimized molecular structure design, which can greatly reduce the adsorption of bacteria and microorganisms on the membrane surface, effectively reducing the risk of fouling. At the same time, the optimized membrane structure design ensures small flux attenuation during long-term operation and always maintains stable water production efficiency, building a solid line of defense for water quality safety in industries with strict water quality requirements such as electronics, chemical industry, electric power and food and beverage [3][5].
