Swimming pool water was treated using an ultrafiltration process using ceramic and polymer membranes for comparison. It was determined that the efficiency of the process depended on the type of membrane used. The polymer membrane decreased the absorbance and concentration of combined chlorine in the pool water to a greater extent than the ceramic membrane. In the case of a ceramic membrane, the concentration of combined chlorine in the permeate exceeded the limit values. During the ultrafiltration process, the permeate flux decreased, causing the blockage of membrane pores. The extent of this phenomenon was similar for both tested membranes. In the case of the ceramic membrane, flushing it with water could significantly restore its initial performance. For both tested membranes, a high regeneration efficiency was observed during chemical treatment with an alkaline solution. SEM photos of the polymer membrane showed low resistance of this polymer to the chlorine present in the swimming pool water.
使用陶瓷膜和聚合物膜通过超滤工艺对游泳池水进行处理以作比较。结果表明，该工艺的效率取决于所使用的膜的类型。聚合物膜比陶瓷膜能更大程度地降低游泳池水中化合氯的吸光度和浓度。对于陶瓷膜而言，渗透液中化合氯的浓度超过了限值。在超滤过程中，渗透通量下降，导致膜孔堵塞。两种测试膜的这种现象程度相似。对于陶瓷膜，用水冲洗可显著恢复其初始性能。在用碱性溶液进行化学处理时，两种测试膜均观察到较高的再生效率。聚合物膜的扫描电子显微镜照片显示该聚合物对游泳池水中的氯耐受性较低。
