Nanoparticle 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 کاملMembrane Distillation for Water Recovery and Its Fouling Phenomena
The total volume of water on Earth is circa 300 million cubic miles, with close to 98.0% being salt water and the remaining 2.0% fresh water. It has been increasingly more challenging to harvest fresh water from surface water, seawater and even from wastewater due to the combination of factors, viz. burgeoning population growth, rapid industrialization and climate change. Recently, membrane dis...
متن کاملTreatment of Simulated Coalbed Methane Produced Water Using Direct Contact Membrane Distillation
Expolitation of coalbed methane (CBM) involves production of a massive amount saline water that needs to be properly managed for environmental protection. In this study, direct contact membrane distillation (DCMD) was utilized for treatment of CBM-produced water to remove saline components in the water. Simulated CBM waters containing varying concentrations of NaCl (1, 20, and 500 mM) and NaHCO...

متن کاملBoron removal from aqueous solution by direct contact membrane distillation.
The removal of boron from aqueous solution by direct contact membrane distillation (DCMD) was studied with self-prepared polyvinylidene fluoride (PVDF) hollow fiber membranes in the present work. The effect of pH, boron concentration, temperature and salt concentration of the feed solution on the boron rejection was investigated. The experimental results indicated that boron rejection was less ...
