Opis:: Changes in concentration of total organic carbon in natural organic matter during UV irradiation have been examined, and especially its biodegradable fraction. The studies have shown better effectiveness of elimination of organic substances for highly contaminated water than that obtained for pre-Treated water. UV irradiation assured the decrease of all fractions of total organic carbon, which indicates the domination of mineralization over the transformation of multi-molecular substances into simpler ones. This means that organic substances were mineralised during UV irradiation. The effective elimination of non-biodegradable dissolved organic substances absorbing UV radiation ensures a very large decrease in potential of disinfection of by-products.

Opis:: Adsorption of clofibric acid (CA) and propyphenazone (PPZ) to virgin granular activated carbon (GAC) and preloaded GAC was evaluated in the absence or presence of natural organic matter (NOM). In spite of lower log K ow, PPZ showed higher selectivity to GAC than CA, which has a carboxylic group. Adsorption competition between CA and PPZ in binary solutes system decreased the amount of individual compound adsorbed to GAC. Adsorption isotherm data obtained in the presence of NOM showed that NOM in bulk solution or preloaded on GAC could significantly reduce the amounts of CA and PPZ adsorbed to GAC.

Opis:: Decomposition kinetics of natural organic substances during the photocatalytic process with a semi-conductor TiO2 has been investigated. In the study, a laboratory reactor Heraeus and in a photocatalytic membrane reactor were used. Simulated solutions of deionized water, surface water and fulvic acids, differing in composition, were tested in the experiment. In order to determine reaction rate constants, the Langmuir–Hinshelwood kinetic model based on the first order reaction was applied. It was found that photocatalytic process enabled effective degradation of natural organic substances although its run was affected by inorganic ions, mainly those producing water hardness, present in water.
