The cleaning effect of a high‐pressure jet of water on a polymeric microfiltration membrane was investigated at different pressures, durations, and angles. The angle of 70° at a pressure of 130 bar and a cleaning duration of 10 s were found to be promising parameters. Throughput measurements show that this cleaning method can restore about 80 % of the initial throughput of the membrane. Analyses by capillary flow porometer and UV‐vis spectrophotometer imply that an impact on the membrane was detectable after 1800 cleaning cycles at a pressure of 130 bar. Therefore, high‐pressure jet cleaning is a promising method for mechanical cleaning of track‐etched microfiltration membranes.

聚合物微滤膜的高压喷射清洗

研究了在不同压力，持续时间和角度下，高压水喷射在聚合物微滤膜上的清洁效果。发现在130 bar的压力下70°的角度和10 s的清洁时间是很有希望的参数。吞吐量测量表明，这种清洁方法可以恢复大约80％的初始膜通量。毛细管流动孔率计和紫外可见分光光度计的分析表明，在130 bar的压力下经过1800个清洗循环后，可以检测到对膜的影响。因此，高压喷射清洗是一种用于机械清洗轨迹蚀刻微滤膜的有前途的方法。
