The article discusses effectiveness of treatment of groundwater with increased natural organic matter content with the use of organic polyelectrolytes. The effects of water treatments were determined by the ionic character of the polyelectrolyte and its dose. Due to the amount of removed general ferric and coloured matters a greater usefulness of anionic and non-ionic polyelectrolytes was shown, while due to decreased turbidity and TOC, cationic flocculants proved more useful. Using the Praestol 2540 semi-anionic polyelectrolyte as the substance aiding the coagulation process decreased the effectiveness of groundwater treatment, especially in terms of the removal of iron and organic substances when using the PIX-112 coagulating agent.
