国家海洋局第二海洋研究所最近研制成功了反渗透卷式淡化组件,该类组件长约1.8米,内径4英寸,选用环氧玻璃钢壳体,内装三个单元膜卷,配用该所研制的醋酸纤维素膜,操作压力可控制在25—40公升/厘米~2的范围。该类组件脱盐率为80—85％,日产水量2.0吨以上,适用于纯水制备,也可用于低盐度苦咸水的脱盐。该类组件研制成功,为发展我国反渗透技术作出了有益的贡献。
Second Institute of Oceanography, State Oceanic Administration has successfully developed reverse osmosis volume desalination module, which is about 1.8 meters long, 4-inch diameter, the use of epoxy fiberglass shell, built-in three unit film roll, with the development Cellulose acetate membrane, the operating pressure can be controlled in the 25-40 liters / cm ~ 2 range. Such components desalination rate of 80-85%, the daily output of 2.0 tons of water or more, suitable for pure water preparation, can also be used for low salinity brackish water desalination. The successful development of such components has made a useful contribution to the development of reverse osmosis technology in China.
