***General Introduction***
This dataset contains data collected during experiments on ammonium recovery by a combined bio-electrochemical and electrochemical system. It is being made public both to act as supplementary data for publication and in order for other researchers to use this data in their own work.
This work was performed at Wetsus, European Centre of Excellence for Sustainable Water Technology, between November 2019 and December 2020.

File: 2022_SGEO-etal-combined_BES_ES.csv - includes the data recorded during the different experimental campaigns: 1.1. stable bio-anode, 1.2. unstable bio-anode - HRES LN 1, 1.3. unstable bio-anode - HRES LN 2.2, 1.3. unstable bio-anode - HRES LN 0.7, 1.4. 5x dilution & high loading, 1.5. 0x dilution & low loading, 1.5. 0x dilution & high loading

The data includes: date [date], experimental day number [day no.], medium type [medium], applied dilution factor [dilution factor], feed rate [feed rate bio anode (L/d)]; Cathode potential [E Cathode (V vs. Ag/AgCl), daily average], Bio anode potential [E bio-anode (V vs. Ag/AgCl), daily average], Bio electrochemcial Cell Voltage [E BES-Cell (V), daily average], Current density Bio electrochemical cell  [j bio-anode (A/m^2), daily average], 
Electrochemical Anode potential [E ES-anode (V vs. Ag/AgCl), daily average], Electrochemical Cell Voltage [E ES-Cell (V), daily average], Current density electrochemical cell [j ES-anode (A/m^2), daily average], measured pH [pH (-)], measured conductivity [conductivity (mS/cm)], measured Chemical Oxygen Demand [COD (g/L)], measured Total Ammonium Nitrogen [TAN (gN/L)], measured concentration of various anions [Chloride (g/L), Nitrite (g/L),
 Nitrate (g/L), Phosphate (g/L), Sulphate (g/L)], cations [Sodium (g/L), Ammonium (g/L), Potassium (g/L), Magnesium (g/L), Calcium (g/L), and organic carbon species [Inorganic Carbon (g/L), Total Carbon (g/L), Total Organic Carbon (g/L)]
abbreviations: n/a = not applicable; n.a. not analysed; n.d. = not detected (below limit of detection; IC Anions < 0.1 mg/L, IC Cations = 0.5 mg/L)
