天津金海湖湖水淡化系统水回收率随湖水含盐量变化数据集（2020年7-11月）

金海湖湖水经精密过滤-超滤预处理，反渗透/纳滤系统脱盐。待压力和流速稳定半小时后，记录水回收率。精密过滤系统采用过滤精度5 μm的袋式滤芯和熔喷滤芯串联，精密过滤操作压力0.3MPa。超滤系统采用聚偏氟乙烯管式膜（平均孔径 0.1 μm，膜管内径8 mm，天津海普尔），超滤操作压力0...The water from Jinha Lake undergoes precision filtration-ultrafiltration pretreatment, followed by desalination via reverse osmosis/nanofiltration systems. After the pressure and flow rate stabilize for half an hour, the water recovery rate is recorded. The precision filtration system adopts a series connection of bag filter cartridges and melt-blown filter cartridges with a filtration precision of 5 μm, with an operating pressure of 0.3 MPa for precision filtration. The ultrafiltration system uses polyvinylidene fluoride (PVDF) tubular membranes (average pore size 0.1 μm, membrane tube inner diameter 8 mm, Tianjin Haipu'er), with an operating pressure of 0... for ultrafiltration.
