Aniline is commonly used in a number of industrial processes. It is known to be a harmful and persistent pollutant and its presence in wastewater requires treatment before disposal. In this paper, the effectiveness of nanofiltration (NF) to remove aniline from aqueous solutions is studied in a flat membrane test module using two thin-layer composite membranes of polyamide (NF97 and NF99HF). The influence of different operational variables (applied pressure, feed concentration and pH) on the removal of aniline from synthetic aqueous solutions was analysed. The experimental NF results are compared with results previously obtained by reverse osmosis. Based on this comparative study, the effective order for aniline rejection is: HR98PP > NF97 > DESAL3B > SEPA-MS05 > NF99HF.
苯胺在许多工业过程中被广泛使用。它是一种有害且持久的污染物,其存在于废水中需要在处理后才能排放。在本文中,使用聚酰胺(NF97 和 NF99HF)的两种薄层复合膜,在平板膜测试模块中研究了纳滤(NF)从水溶液中去除苯胺的效果。分析了不同操作变量(施加压力、进料浓度和 pH 值)对从合成水溶液中去除苯胺的影响。实验 NF 结果与反渗透先前获得的结果进行了比较。基于这项比较研究,苯胺排斥的有效顺序是:HR98PP > NF97 > DESAL3B > SEPA-MS05 > NF99HF。
