Abstract

In this study the removal of humic substances from model-solution and well-water using four different ultrafiltration membranes has been investigated. The permeates were analysed by UV254nm absorbance, TOC and DOC measurements. Based on our experiments it can be established that the examined membranes are suitable for the humic acid removal. The removal efficiency of all investigated membranes was relatively high (≈90%) in case of model-solutions. The rejection of the membranes in case of natural well-water was lower (≈60-70%) due to different composition of the humics.
