, 1999 一种中空纤维复合膜分离器漏丝检测方法，将待分离的混合气体压缩作为原料气送入膜分离器，在渗透气侧逐一取１根或２～５根丝的渗透气进行气体分离分析，如果渗透气中快气（混合气体中渗透率大的气体）浓度相对其它中空纤维的浓度低，可以断定这根或这些中空纤维必有漏丝。本发明可以检测出分离器中某根丝的涂层情况，并借对该漏丝的处理提高分离器产品的合格率 ...

Gongye shui chuli采用非浸没式超滤（NSUF）技术净化处理煤矿矿井水，从NSUF陶瓷膜的操作参数与性能、膜污染清除、超滤浓水加药絮凝以及污泥压滤脱水性能等方面进行了现场试验研究。控制超滤产水率在70%条件下，NSUF“膜面流”操作方式与在线物理清洗相结合，可以清除滤层堵塞和膜污染，使膜通量与跨膜压差得到恢复，NSUF装置实现连续稳定运行。超滤浓缩产生的30%浓水在添加PAC和PAM后，沉降比达到4.3%，澄清液返回到超滤单元。絮凝污泥通过板框压滤进行脱水处理，滤饼含水率约75%。采用三级NSUF—絮凝沉淀 ...

, 2019 聚醚砜(PES)超滤(UF)膜可用于甘蔗糖蜜的澄清和脱色,能够实现糖蜜中蔗糖和色素的回收.研究发现,随着使用的UF膜孔径减小,截留的污染物浓度增加且孔内污染愈加严重,导致膜的不可逆污染加剧.截留分子量为100 000的大孔UF膜适合糖蜜澄清,截留分子量为5 000的小孔UF膜可高效分离色素和蔗糖.在UF膜表面涂覆聚多巴胺后,再接枝不同聚合物,如聚乙烯亚胺(PEI)、壳寡糖(CS)和氧化海藻酸钠(ADA),以调控其亲水性和荷电性,发现膜的荷电性是影响膜污染形成的主导因素.在接枝ADA后 ...
