***General Introduction***
This dataset contains data collected during experiment on foulant fractionation of fresh water in reverse electrodialysis. 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 in Wetsus, European Centre of Excellence for Sustainable Water Technology, between October 2019 and December 2019. 
The article describing this data has been publisehd with this DOI: https://doi.org/10.1016/j.desal.2021.115277


File: LIMS_analytical results.csv - includes the analytes measured from all the sampling points, namely A1, B1, C1 of fresh water and A2, B2 of seawater. 
File: Total_suspended_solids.csv - includes the data of the volume of the sample, the weight of the crucible and filter without the sample, and the dry weight of crucible, filter and sample after overnight in the 105 C oven. The total suspended solids value is calculated by subtracting the initial weight of the crucible and the filter from the weight after 105 C oven and adjusting the units to have the final result in mg/L
File: Turbidity.csv - includes the turbidity data measured for each sampling point, namely A1, B1, C1 of fresh water and A2, B2 of seawater
File: Pressure_drop.csv - includes the data measured of pressure drop for each stack in the day of experiment.
Folder: Ivium curves - includes the data recorded by the Potentiostat (Ivium). Each file contains the conditions of the performed measurement. The recorded variables for each stack were: Date; start time of the method; time [s]; current [A]; voltage [V]response. The reader is advised to open these files in the Ivium software, where visualization of the data is clearer. 
Folder: DIPA_files - each folder is organized by sampling date and contain 4 files of the measurements of each sampling point: A1 and B1 for fresh water and A2 and B2 for seawater. The column "size (micrometer)" represent the size class of particles and "Local" represents the volume this size class represents in relation to other classes.
