To satisfy water requirements, seawater desalination represents one of the most sustainable solutions. In recent decades, membrane distillation has emerged as a promising thermal desalination process that may help to overcome the drawbacks of traditional desalination processes. Nevertheless, in membrane distillation, the temperature at the feed membrane interface is significantly lower than that of the bulk feed water, due to the latent heat flux associated with water evaporation. This phenomenon, known as temperature polarization, in membrane distillation is a crucial issue that could be responsible for a decay of about 50% in the initial transmembrane water flux. The use of plasmonic nanostructures, acting as thermal hotspots in the conventional membranes, may improve the performance of membrane distillation units by reducing or eliminating the tempe...

In this study, moving bed biofilm reactor (MBBR), membrane bioreactor (MBR), and direct contact membrane distillation (DCMD) treatment steps were integrated successively to obtain the combined advantages of these processes for industrial wastewater treatment. The MBBR step acts as the first step in the biological treatment and also mitigates foulant load on the MBR. Similarly, MBR acts as the second step in the biological treatment and serves as a pretreatment prior to the DCMD step. The latter acts as a final treatment to produce high-quality water. A laboratory scale integrated MBBR/MBR/DCMD experimental system was used for assessing the treatment efficiency of primary treated (PTIWW) and secondary treated (STIWW) industrial wastewater in terms of permeate water flux, effluent quality, and membrane fouling. The removal efficiency of total dissolved solids ...

In this paper two innovative processes (i.e., membrane condenser and membrane crystallization) will be described and discussed. Membrane crystallization can be used in desalination in combination with membrane distillation and pressure driven membrane processes (such as nanofiltration or reverse osmosis) to achieve high recovery factor combined to salt crystals production.The innovative membrane condenser can be used for the selective recovery of evaporated waste water and contaminants from industrial gases. This process can be also used for pre-treating gas streams that require further separation for the recovery of a defined species (such as pre-treatment of flue gas when used for CO2 capture, biogas for bio methane production, etc.). The current status, the separation principle, the utilized membrane materials and membrane configurations, and the application fields are described and discussed. The ...

Membrane condenser is an innovative technology that was recently investigated for the recovery of water vapor for waste gaseous streams, such as flue gas, biogas, cooling tower plumes, etc. Recently, it has been also proposed as pre-treatment unit for the reduction and control of contaminants in waste gaseous streams (SOx and NOx, VOCs, H2S, NH3, siloxanes, halides, particulates, organic pollutants). This perspective article reports recent progresses in the applications of the membrane condenser in the treatment of various gaseous streams for water recovery and contaminant control. After an overview of the operating principle, the membranes used, and the main results achieved, the work also proposes the role of this technology as pre-treatme...

Polymeric membranes were used in this investigation. The tested polymeric membranes included lab made polyvinylidene fluoride (PVDF) membranes produced under different processing conditions and dope compositions and having different characteristics (PVDF1 and PVDF2). In addition, two commercial polypropylene (PP) based membranes (PP1 and PP2) were also tested. The experimentation was carried out under various hydrodynamic and thermal conditions. In all the performed experimentation, the polymeric membranes showed reliable and stable performance. Analysis of the collected permeates indicates that the membrane distillation (MD) process is an interesting solution for the treatment of produced water, with the overall salt rejection factor greater than 99% and total carbon rejection higher than 90%. An economical evaluation was carried out to assess the feasibility of the process. Data from cost analysis indicate that for MD operating at 50 °C and with a recovery of 70%, water cost is 0.72 /m3whenthetemperatureoftheproducedwaterfedtotheplantis50°Cand1.28/m3 when the temperature of the produced water fed to the plant is 50 °C and 1.28 /m3whenthetemperatureoftheproducedwaterfedtotheplantis50°Cand1.28/m3 if 20 °C is the temperature of the produced water fed to the plant.
