Rejection mechanisms for contaminants in polymeric reverse osmosis membranes

Despite the success of reverse osmosis (RO) for water purification, the molecular-level physicochemical processes of contaminant rejection are not well understood. Here we carry out non-equilibrium molecular dynamics (NEMD) simulations on a model RO membrane to understand the mechanisms of transport and rejection of both ionic and inorganic contaminants in water. While it is commonly presumed t...

Prediction of Hydrate Formation for the Systems Containing Single and Mixed Electrolyte Solutions

In this work the effect of electrolytes on hydrate formation was investigated. To do so, a new model was used in predicting the hydrate formation conditions in presence of both single and mixed electrolyte solutions. The new model is based on the van der Waals - Platteeuw hydrate equation of state. In order to evaluate the values for the activity of water in electrolyte solutions t...
