Abstract

The competitive interactions of UV-absorbing and non-absorbing NOM (natural organic material) were studied in pilot columns of GAC (granular activated carbon). Sampling ports through the columns provided SUVA (Specific UV Absorbance) profiles and demonstrated the preferential removal of humic (UV₂₅₄) and lignin-type (UV₂₆₅, UV₂₈₀) substances compared to TOC characterised NOM. EBCT (empty bed contact time) has a significant effect on depth profiles. GAC type is also important for the extent of competitive interactions between NOM components.
