***General Introduction***

This dataset contains theoretical and model script data for 2D mass transport model for an RO module. 
It is being made public to act as supplementary data for publication and for other researchers to use it in their work.
The theoretical study was performed in Wetsus, in collaboration with the Department of Process Engineering and Technology of Polymeric and Carbon Materials, Wroclaw University of Science and Technology University, Wroclaw, Poland, between September 2023 and July 2024.

File: Without_pressure_drop_data.cvs - includes the theoretical data for the RO module (along the module length). The computation excludes the hydraulic pressure drop along the module length.

File: With_pressure_drop_data.cvs - includes the theoretical data for the RO module (along the module length). The computation includes the hydraulic pressure drop along the module length.

File: Parametric_study_data.cvs - includes the theoretical data for the RO module with sensitivity analysis on the feedwater rate and the applied feed pressure.

File: Length-width_optimization_data.cvs - includes the theoretical data for the RO module with length-width optimization. The computation includes pressure drop along the module length and assumes a fixed membrane area of Am = 1 m^2.

File: Membrane_area_variation_data.cvs -  includes the theoretical data for the RO module with a variation of active area for 1 membrane sheet. The computation includes pressure drop along the module length and assumes a fixed inlet feed cross-flow velocity and applied pressure.

File: RO_module_MAPLE-V_script.mws - includes the modeling script (in MAPLE-V format) with the transport and boundary equations, input parameters, and output panels.

File: RO_module_MAPLE-V_script.txt - includes the modeling script (in text format) with the transport and boundary equations, input parameters, and output panels. 	

All modeling equations are included in the manuscript and the supporting information. DOI: to be added
