AB  - After the lake water of Jinhai Lake was pre-treated by precision filtration-ultrafiltration, the pre-treated effluent was pumped by a high-pressure pump (CRN3-29, Grundfos, China) into the desalination system fitted with different quantities of nano-filtration membranes, which were made of commercialized polyamide 4040 rolled-type membrane modules (VNF2, Guiyang Times Warden Co., Ltd.). After the pressure and flow rate were stabilized for half an hour, the salinity data of the produced water was recorded and the desalination rate was calculated. The operating pressure was 1.3MPa, the salt content of influent water was 7.5g/L, the water temperature was 30±2℃, the influent flow rate was 2m3/h, and the number of membrane modules was 6-8. The measurement is accurate to two decimal places. The desalination rate of the nanofiltration system is higher than 80%, reaching the assessment index of the task book. This dataset is mainly applied to the study of brackish water desalination.
