Considerable effort is currently being put towards process intensification to design more sustainable and energy-efficient processes. Hybrid distillation-membrane processes are prime examples of such intensified In this work, different strategies presented for how handle the complexity membrane network hybrid in terms initialisation convergence simulation optimisation. A superstructure approach...

Management of in-land reverse osmosis (RO) desalination brines generated from surface brackish waters is a current challenge. Among the different near-Zero and Zero Liquid Discharge (ZLD) alternatives, Membrane Distillation (MD), in which transport water thermally driven, appears as an attractive technology if residual heat source available. The aim this study was to identify limits Direct Cont...

Abstract The outstanding capabilities of membrane distillation (MD) process to handle highly saline solutions are still driving research efforts take this the industrial level. MD scale-up remains a challenge as objective increasing performance faces several design issues imposed by intrinsic physical constraints. Among major hurdles encountered with an increase in active area stands temperatur...

In the article, a new air-blowing vacuum membrane distillation (AVMD) process is proposed, and it forms the air-liquid flows in the membrane by forcedly blowing airs to the hot feed liquids circularly flowing in the hollow fiber membrane, and forms the AVMD system to enhance the turbulent degree of the liquids. The intense disturbance of air bubbles and the strong cutting power at the surface o...

Separation of ethylene from ethane in commercial processes is expensive both in capital and operating costs. This study has evaluated the feasibility of using facilitated transport membrane technology for improving the separation process. Simulation and optimization of various distillation/membrane hybrid configurations as well as stand-alone membrane cascade systems have been examined under di...

The main obstacles to scaling up membrane distillation (MD) on a commercial level are fouling and temperature polarization. Therefore, in this study, the significance of pulsation feed flow phenomenon was used for (DCMD) polarization, comparisons were made using steady-state flow. Two different Hertz amplitudes trends DCMD sources water, including distilled seawater, wastewater. Compared flow, ...

Polyvinylidine fluoride (PVDF) hollow fiber and nanofibrous membranes are engineered and successfully fabricated using dry-jet wet spinning and electrospinning techniques, respectively. Fabricated membranes are characterized for their morphology, average pore size, pore size distribution, nanofiber diameter distribution, thickness and water contact angle. Direct contact membrane distillation (D...

The removal of trace organic compounds (TrOCs) by a novel membrane distillation-thermophilic bioreactor (MDBR) system was examined. Salinity build-up and the thermophilic conditions to some extent adversely impacted the performance of the bioreactor, particularly the removal of total nitrogen and recalcitrant TrOCs. While most TrOCs were well removed by the thermophilic bioreactor, compounds co...
