Simplified flux prediction in direct-contact membrane distillation using a membrane structural parameter
• Membrane structural parameters were evaluated for use in predicting water flux. • Membrane constant containing non-coupled membrane properties was introduced. • Membrane constant requires simple measurements and inexpensive analytical equipment. • Membrane constant correlates well with experimental water flux. • Comprehensive collection of MD membrane properties and water fluxes made availabl...
متن کاملFactors contributing to flux improvement in vacuum-enhanced direct contact membrane distillation
• VEDCMD has higher water flux than DCMD and PEDCMD. • Higher flux with vacuum applied may be partially due to lower membrane compaction. • Higher flux with vacuum applied may be partially due to lower membrane air pressure. • Pressure differences due to vacuum or pressure enhancement has a minimal effect on flux. a b s t r a c t a r t i c l e i n f o Low water flux in membrane distillation (MD...
متن کاملExperimental study of desalination using direct contact membrane distillation: a new approach to flux enhancement
New membrane distillation configurations and a new membrane module were investigated to improve water desalination. The performances of three hydrophobic microporous membranes were evaluated under vacuum enhanced direct contact membrane distillation (DCMD) with a turbulent flow regime and with a feed water temperature of only 40 ◦C. The new configurations provide reduced temperature polarizatio...
متن کاملNanoparticle Separation Using Direct Contact Membrane Distillation and Its Fouling Study
Direct contact membrane distillation (DCMD) which emerges as an alternative separation technology can effectively perform a colloidal separation process under thermal driven force. DCMD is capable of extracting pure water from aqueous solutions containing non-volatile nanoparticles through the hydrophobic microporous membrane when a vapour pressure difference was established across the membrane...
متن کاملA scaling mitigation approach during direct contact membrane distillation
Membrane scaling during the treatment of aqueous solutions containing sparingly soluble salts by direct contact membrane distillation (DCMD) was investigated. The results reveal that membrane scaling caused by CaSO4 was more severe than that by CaCO3 or silicate. However, under the experimental condition used in this study and at feed and distillate temperature of 20 C and 40 C, respectively, C...
