Three ultrafiltration membranes were prepared using phase separation techniques. The membranes were characterized by scan electron microscope, porosity, pore size distribution measurement, and mechanical properties. The membrane performance was carried out using synthetic solutions from humic acid and tap water to express the contaminated drinking water. The polyvinylidene difluoride (M2) has the highest tensile strength 33.2 MPa with elongation of 52.3%, while polyacrylonitrile (M3) has the lowest mechanical properties, tensile strength 16.4 MPa with elongation of 42.7%. Polyethersulfone membrane (M1) provides the highest removal of humic acid, which was 99.5, 98.8, and 98.2% using feed concentrations 0.1, 0.3, and 0.5 g/l, respectively, while M3 provides the highest permeate flux which was 250, 234.4, and 201.4 l/m² h using feed concentrations 0.1, 0.3, and 0.5 g/l, respectively. Analysis of water samples indicates that the prepared membranes can be used to treat the contaminated drinking water which produced the high quality of drinking water after treatment.

用于水处理的低压膜

使用相分离技术制备了三种超滤膜。通过扫描电子显微镜，孔隙率，孔径分布测量和机械性能表征膜。使用腐殖酸和自来水的合成溶液进行膜性能分析，以表达被污染的饮用水。聚偏二氟乙烯（M2）的最高拉伸强度为33.2 MPa，伸长率为52.3％，而聚丙烯腈（M3）的机械性能最低，拉伸强度为16.4 MPa，伸长率为42.7％。聚醚砜膜（M1）在进料浓度分别为0.1、0.3和0.5 g / l时，腐殖酸的去除率最高，分别为99.5％，98.8和98.2％，而M3则提供了最高的渗透通量，分别为250、234.4，和201.4 l / m ² h分别使用0.1、0.3和0.5 g / l的进料浓度。对水样的分析表明，制备的膜可用于处理受污染的饮用水，经过处理后可产生高质量的饮用水。
