  • Use of a stable carbon isotope to assess the efficiency of a drinking water treatment method with C▫$O_2$▫
    Poberžnik, Mojca ; Leis, Albrecht ; Lobnik, Aleksandra
    CO2 gas with a special isotopic signature (?13C = -35.2% vs. VPDB) was used as a marker to evaluate the efficiency of a drinking water treatment method and the effect of an ultrasonic (US) stirrer. ... This treatment was developed to prevent precipitation and corrosion effects in water-supply systems. The research work was performed using a laboratory-scale pilot plant that was filled with tap water. The stable isotope analyses of ?13C-DIC (Dissolved Inorganic Carbon) in the water samples indicated that the maximum content of added CO2 gas in DIC was in the range of 35 to 45%. The use of the US stirrer during the entire experiment decreased the method's overall efficiency by 10%, due to degassing at a late stage of the experiment but accelerated the dissolution process in the early experimental stage.
