20.500.12556/DKUM-27253 Use of a stable carbon isotope to assess the efficiency of a drinking water treatment method with CO[sub]2 Use of a stable carbon isotope to assess the efficiency of a drinking water treatment method with CO2 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. 13C stable isotope carbon dioxide carbonate equilibrium corrosion drinking water limestone true false false Angleški jezik Angleški jezik Neznano 2012-06-01 10:12:00 2012-06-01 10:12:00 2022-04-15 03:43:50 2019-07-10 12:13:49 2012 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 628.3 15813910 0273-1223 URN:SI:UM:DK:O0TBGN06 http://www.iwaponline.com/wst/06506/0983/065060983.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=36511 Fakulteta za strojništvo 0 0 0
