In recent years forward osmosis (FO) process has attracted considerable attention in the field of watertreatment and desalination. However, the lack of sufficient information on all possible parameters, affect-ing the process performance, is a major obstacle that avoids improving the function of this method. Inthis study, an algorithm based upon a reliable model was developed for osmosis through asymmetricmembrane oriented in FO mode to be applied in agent-based model. This model was built in the NetLogoplatform, which is a programmable modeling environment for simulating natural phenomena. The feasi-bility of this modeling was proven by comparing the simulation results and empirical data obtained fromliterature. The influence of net bulk osmotic pressure difference between the draw solution (DS) and thefeed solution (FS) on average water flux was studied for various draw solutes. Furthermore, the effects ofprocess parameters, including temperature, length of module, FS cross-flow velocity, pure water perme-ability coefficient, and structural parameter of membrane on average water flux were investigated. As aresult, it could be concluded that Netlogo agent-based model had the quite well potential to simulate theFO process.
