摘要
Abstract
In order to meet the drinking water standards by using the brackish water as raw water in northwest China, a typical polyamide nanofiltration (NF) membrane has been fabricated and used to treat the brackish water after pretreatment of coagulation + sedimentation+ quartz sand filtration. The results showed that this NF membrane can effectively rejection different ions and dissolved organic matters in the brackish water, which ensured the permeate water could meet the requirements of the Standard for drinking water quality (GB5749-2006). The operation pressure of 0.5 MPa was proper according to the balance of membrane fouling and solute rejection. The membrane fouling was the combined effect of organic fouling and inorganic fouling, which were induced by natural organic matters and inorganic precipitate, respectively.关键词
