Yongtae kim Posted May 18, 2018 Share Posted May 18, 2018 Dear GWB support forum team, My name is Yongtae kim, in GIST, South Korea. I'm doing experiment with Electrocoagulation technology. when electrocoagulation process started. Fe2+, OH- ions generated and make Fe(OH)3. That precipitate absorb arsenic in solution. In real experiment, PO4, SiO2, HCO3 are in competition with arsenic removal by absorption. So, arsenic removal efficiency is reduced by that anions. However, in GWB reaction modeling, only PO4 act negative roles. SiO2 is absorbed with Fe(OH)3 but that fraction is too small in GWB software. HCO3 is not absorbed in GWB. I was wondering if the mechanism was not included in the background of the GWB program or I was wrong. A file is attached and I'd appreciate it if you could answer it. Thank you.
