各位海友:我们最近在RO清洗过程中出现了非常大的难题:反渗透清洗前:进水压力0.98MPa,段间压力0.78MPa,浓排压力0.71MPa,一段压差0.2,二段压差0.07,产水量56,浓排22,产水电导4.94.采用碱洗+酸洗后:进水压力1MPa,段间压力0.88MPa,浓排压力0.78MPa,一段压差0.12二段压差0.1,产水量45浓排20,产水电导6.59.清洗后压差下降,电导变化不大,单产水量明显下降。我们又对第二套膜只采用碱洗,也出现了以上情况。怀疑未冲洗干净,对第二套膜不加任何清洗液,采用脱盐水大流量冲洗(加温后),产水量又下降了15方。我们使用的是德国朗盛膜,代理商和药剂厂家均未出现过此种情况。对膜端盖拆开检查非常干净,代理商已安排拆膜送厂家解剖分析。请问哪位海友知道原因,或知道哪家出现过此种情况,希望告知,不胜感谢。

看样子只有我们一家出现这种情况了
