Abstract

Changes in the properties of a FiTreM track membrane filter with a 0.45 μm pore diameter during water filtration and changes in filtration rate during continuous water filtration were studied. It was established during the experiments that the decrease in filtration rate through a track membrane filter depends both on the occurrence of suspensions and colloid compounds, as well as on the physical properties of the filter. This is also due to the change in membrane permeability due to partial destruction of a filter, its compaction during use, as well as the accumulation of a negative charge on the pore surface due to the dissociation of COOH groups.

履带膜过滤器使用过程中的行为特征分析

摘要

研究了水过滤过程中孔径为0.45μm的FiTreM履带膜过滤器的性能变化以及连续水过滤过程中过滤速率的变化。在实验过程中已确定,通过履带式滤膜的过滤速率的下降既取决于悬浮液和胶体化合物的出现,也取决于过滤器的物理性质。这也归因于由于过滤器的部分破坏,使用中的压实以及由于COOH基团的解离而在孔表面上积累的负电荷而引起的膜渗透性的变化。
