Standard jar testing was applied to three types of water, two of natural and one of synthetic origin (tap water with added leach of peat). The NOM samples were fractionated by standard resin adsorption technique into four components: very hydrophobic acids, slightly hydrophobic acids, hydrophilic charged, and hydrophilic neutral. The results showed that the NOM removal efficiency depends on the NOM character and using destabilising reagents and reaction conditions. In comparison with aluminium sulphate, the ferric one proved to be more efficient in all tested cases.
