  2. 1. Aspects of drinking water supply in areas of humic water

    Author : Talis Juhna; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : The thesis investigated several aspects that are important for drinking water supply from waters with high amounts of humic substance (humic water). The results showed that the composition of humic substances is important in their sorption to aquifer material during surface water artificial recharge through infiltration basins to groundwater.
