An incremental approach has been utilized to develop a fully integrated diffusion
based membrane mass transfer model that considers concentration, recovery and osmotic
pressure (IMOP) using finite elements. Osmotic pressure is incorporated into the model
using correction coefficients that are calculated from boundary conditions as determined
by the feed and concentrate stream osmotic pressures. Comparison to other models and
verification of the developed model is presented using independently developed water
quality and membrane operating conditions from full scale plants as described in the
US Environmental Protection Agency (USEPA) Information Collection Rule database and other independently developed pilot
scale data. The results and statistical analyses show that the IMOP improves prediction
of diffusion controlled permeate water quality significantly. Includes 11 references, tables, figures.
