Membrane distillation (MD) for water treatment is significantly impaired by the scaling of dissolved minerals. The type and content minerals generally measured as total solids (TDS) in hypersaline brines not only reduce MD flux but also control behavior on membrane surface. scaling-induced pore blockage further reduces eventually leads to wetting. problem even more pronounced produced (PW) it c...

To date, the membrane development for distillation (MD) application is growing in line with increasing volume of various types wastewaters discharged into environment. MD a liquid-vapor separation process and hydrophobic used to retain liquid. Theoretically, can achieve 100% rejection non-volatile components that dissolved feed liquids. As result, has received significant attention water recove...

The aim of this study is the utilization membrane distillation (MD) in treatment hydrothermal liquefaction wastewater (HTL-WW) to recover ammonium condensate. Experiments were carried out using MD under air–gap configuration with HTL-WW pretreated via Ultrafiltration. results showed stability long-term operations, up 36 days and through a wide range feed temperatures, from 30 °C 60 (Coolant tem...

Abstract The importance of membrane technology development in our daily life cannot be overemphasized. Over the past decades, has become very popular providing potable water for mankind. However, old technologies (such as reverse osmosis and ultrafiltration) which are highly energy intensive still common treatment industries. In this review, capability low consumption distillation (MD) is revie...

In this work, Direct Contact Membrane Distillation (DCMD) was applied for the treatment of municipal wastewater collected from primary clarifier a plant (MWWTP). The water flux at 60℃ and 20℃ feed permeate side, respectively 51 kg/m2h in treating effluent. Meanwhile, electrical conductivity distillate good range 1.5 – 1.8 S/cm. Most representative parameters reuse (SS, nitrate, nitrite, phospha...

Abstract This work presents an experimental validation of MD unit coupled with a sweeping gas membrane (SGMD) using solar energy distillation energy. station is installed at the University Kairouan in Tunisia. SGMD least used (MD) configuration, and it very expensive to build. completely remove solutions containing non-volatile compounds such as salts recover only high-purity water. A theoretic...

Optimization and design of full-scale membrane distillation (MD) systems usually require Sherwood Nusselt correlations that are developed from lab-scale systems. However, entrance effects in can significantly impact heat, mass momentum transfer the reactor, therefore affect accuracy experimental correlations. Here, Computational Fluid Dynamics (CFD) simulations using OpenFOAM performed to under...

In this study, the influence of the salts as an additive on the performance of the membrane was investigated and an extensive work was performed to optimize PVDF hollow fiber membranes through a response surface methodology (RSM). The prepared membranes were characterized by SEM, contact angle and LEP measurement. Then, the RSM was used for the optimization of surface pore size, porosity and hy...

Membrane distillation is a process that utilizes differences in vapor pressure to permeate water through a macro-porous membrane and reject other non-volatile constituents present in the influent water. This review considers the fundamental heat and mass transfer processes in membrane distillation, recent advances in membrane technology, module configurations, and the applications and economics...

Abstract Membrane distillation (MD) is a novel desalination technology that has potential to produce distilled quality water from high salinity brine streams. The driving force for MD the vapor pressure difference across hydrophobic membrane resulting in transfer of hot cold side. This contacts surface and condenses distillate. paper reviews recent and/or multi-year research programs focused on...
