Hydrophobic membrane

Surface modifying macromolecules (SMMs) were synthesized and blended into the casting solution of polyethersulfone (PES) membranes. The solution was cast to films on the glass plate. The cast films were placed in a temperature-controlled oven with forced air circulation to remove the solvent, before

Osmotic membrane distillation (OMD) is a novel membrane process that facilitates the concentration of aqueous solutions under mild operating conditions. The main drawback of OMD, like any other membrane process, is relatively low flux. In the present work acoustic field has been applied for the enha

Pure water direct contact membrane distillation experiments were carried out. A model based on a dusty-gas model of gas transport through porous media showed good agreement with the experimental results over the entire range of feed temperatures and recirculation rates studied. The model was also us

Membrane distillation (MD) has been used for water production from brines at temperatures below 50°C. The effect of recirculation rate, mean temperature and salt concentration on the water fluxes has been measured. The experiments have been carried out with a commercial composite membrane formed by

Transmembrane evaporation (often called membrane distillation) carried out in a countercurrent flow module, in which incoming cold seawater is heated by the condensing product water flow, is a promising technology for low-cost seawater desalination. This paper presents a model for preliminary design
