This paper presents a mathematical modeling for a series of experiments in which humic acid (AH) and calcium chloride (CaCl2) were used, in order to visualize the amount of contaminant before and after the nanofiltration (NF) process, using Excitatio

In recent years, membrane technology is increasingly being studied and thus became even more used in the production of drinking water. However, the presence of foulants in natural waters, as humic acids, affects strongly the efficiency of membrane pr

Cross flow filtration is the typical way that water is filtered in membrane technology; that means that feed solution passes tangencially over the membrane and rejected components are washed away of the membrane by the rejected stream. In such a way,
