Experimental and Theoretical Investigations of a Novel Multi-Stage Direct Contact Membrane Distillation Module
Global climate change and variability have a negative impact on a water supply and quality in remote areas by reducing water availability and contaminant dilution. This will continue to be exacerbated by limited and inadequate water supply, insufficient water treatment and low infrastructure. Thus, an economic desalination system with a small scale and footprint for such regions is strongly dem...
متن کاملSolar thermal powered desalination: membrane versus distillation technologies
Multiple Effect Distillation (MED) is generally considered to be the desalination technology most suited to integration with concentrating solar thermal collectors on a medium to large scale. However the cost and energy requirement of Reverse Osmosis (RO) have fallen significantly in recent years, so that solar thermal powered RO deserves consideration. We compare commercial desalination proces...
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 کاملElectrical Thermal Network for Direct Contact Membrane Distillation Modeling and Analysis
Membrane distillation is an emerging water distillation technology that offers several advantages compared to conventional water desalination processes. Although progress has been made to model and understand the physics of the process, many studies are based on steady-state assumptions or are computationally not appropriate for real time control. This paper presents the derivation of a novel d...
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...
