The code is a compilation of forward osmosis (FO) flux models that can be used to calculate water permeability (A), salt permeability (B) and structural parameter (S) of the FO membrane. The experimental data (Cd, Cf, Jw, Js, feed and draw flow rates and temperature and hydraulic diameter) can be passed by modifying the initial lines of the code. The experimental data should be obtained following the protocol given in (Tiraferri 2013).

The code contains physicochemical properties (Osmotic pressure, density, dynamic viscosity, diffusivity) relations for NaCl and MgCl2 obtained from OLI at 25C and 1atm (Martin 2020). The code calculates A,B,S parameters and goodness of fit metrics (R2, RMSE and RMSPE).

The code covers three models presented in the research literature:
