自七九年底,我所水处理应用了反渗透淡化器,并加强对其它纯化手段的管理和操作,基本完成本所超纯水制备工艺流程,运行正常,纯水水质较为满意。为了能较快地提高超纯水的产水量,根据反渗透和超过滤在纯水中的主要作用,为此,1981年4月,由天津纺织工学院提供中空聚砜超过滤器,应用于超纯水制备工艺。
Since the end of 1979, our company has applied reverse osmosis desalination equipment in water treatment, and strengthened the management and operation of other purification methods. We basically completed the ultrapure water preparation process of the Institute. The operation was normal and the pure water quality was satisfactory. In order to rapidly increase the water production of ultrapure water, according to the main role of reverse osmosis and ultrafiltration in pure water, for this purpose, in April 1981, a hollow polysulfone ultrafilter provided by Tianjin Textile Engineering Institute was applied to super Pure water preparation process.
