Fig. 1From: Hydrogen sulfide removal from geothermal fluids by Fe(III)-based additivesExperimental set-up: The fluid flows from the two wells (TH 1 and 2; a) first into the reaction container (b), where the Fe(III) additive can be injected and an air compressor is connected to. At the reaction container, also a flow-through cell with electrodes to measure pH, redox, dissolved oxygen (DO) and electric conductivity is installed. After passing through the filter (c), the same physicochemical parameters were measured in a monitoring device (FluMo; d). Sampling was possible at (s)Back to article page
