In this work, three different graphene-based materials, namely graphite oxide (GrO), thermally reduced graphite oxide (T-RGrO) and ascorbic acid multi-phase reduced graphene oxide (AMP-RGO), were synthesized and used to produce mixed matrix membranes (MMM) based on Matrimid®5218 for as separation. From the samples produced, a complete set of characterization was performed including XRD, FTIR, TGA and SEM to relate with the gas separation performance using H2, CO2, O2, N2 and CH4. For all the gases studied, the results showed that membrane permeability was inversely proportional to the gas molecular size. This behavior was associated to multi-phase reduced graphite oxide (AMPRGO) being an excellent gas barrier for large gas molecules, especially for CH4. The results showed that the H2/CH4 ideal selectivity increased to 231 which represents a 328% improvement for M/AMP-RGO 0.1 compared to the neat matrix. The CO2/CH4 selectivity was 79.8 for M/AMP-RGO 0.2 wt.% which represents a 344% improvement compared to the neat polymer. These results confirmed that these membranes can be used for methane separation such as in ammonia plants (H2/CH4) or biogas upgrading/natural gas purification (CO2/CH4).

Membrane Condenser (MC) is a novel membrane contactor operation recently investigated for the valorization of industrial waste gaseous streams. In particular, until now, it was applied for water recovery from flue gas, cooling tower plumes, etc. More recently, its effectiveness and flexibility in contaminants (such as, NH3 , HF, SO2 ) removal and control from waste gaseous streams was also proved. In the present work, the application of membrane condenser for water recovery as well as microparticles removal from gaseous streams are presented. Experimental tests showed that microparticles did not affect membrane condenser performance, neither in terms of water recovery nor in term of fouling. Moreover, the carried-out tests revealed also that the complete retention of particles can be achieved only through the proper choice of the membrane, with pore size lower than particles diameter.

This investigation indicates the ability to selectively graft glycidyl methacrylate (GMA) only from the external surface of regenerated cellulose (RC) ultrafiltration (UF) membranes using activator generated electron transfer (AGET) atom transfer radical polymerization (ATRP). This controlled polymerization resulted in epoxy functionalized polymer brush ends. Further reaction of the terminal epoxy groups provides a flexible platform to introduce desired functionalities either by electrophilic or nucleophilic epoxy ring opening. Selective grafting from the external membrane surface was achieved by using an appropriate pore filling solvent prior to modification. A high viscosity pore filling solvent that is immiscible with the reactive monomer solution used during surface modification was the most effective in supressing grafting from the internal pore surface. The effects of grafting on membrane performance were evaluated by determining water permeability and protein rejection.

In this study, the applicability of nanofiltration (NF) membranes as a pretreatment prior to reverse osmosis (RO) in seawater desalination was investigated. The membranes used wereNF270 and NF90 as the NF membranes, while the brackish water (BW) RO membrane BW30 was used as the RO membrane. In desalination tests, permeates of the NF membraneswere collected and used as the feed to the BW30 membrane. The calculated permeate fluxes were 6.7 L/h.m2, 11.3 L/h.m2, 24.3 L/h.m2, and 36.6 L/h.m2 for single BW30-35 bar,NF270-30 bar + BW30-35 bar, NF90-30 bar + BW30-25 bar and NF90-30 BW30-35 bar, respectively. The calculated water recovery and rejected salt values were 51.6%, 41.4%,24.8%, 15.4% and 98.2%, 98.2%, 96.0%, 91.0% for NF90-30 bar + BW30-35 bar, NF90-30 bar + BW30-25 bar, NF270-30 bar + BW30-35 bar and single BW30-35 bar, respectively.The qualities of the product waters of integrated systems (NF+BWRO) and the single BWRO system were also investigated. Boron rejection was fairly well with average boronrejections of 59.3% and 60.2% by NF90-30 bar + BW30-25 bar and NF90-30 bar + BW30-35 bar combinations, respectively while single BW30-35 bar gave an average rejection of49.6%. The results obtained showed that the quality of product water obtained using single BWRO did not comply with the irrigation standards, while the integrated systems providedtotal compliance to irrigation standards with the exception of boron.

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 distillation (MD) emerges as a promising cost-effective thermal driven sustainable water recovery technology when integrated with renewable energy sources. However, one of the major challenges for MD is the membrane fouling, which has been gaining popularity in the recent literature, as well. The membrane fouling propensity for MD is very much depends on the type of feed water, suitability of membrane and the operating conditions. The objective of this review is to investigate the fouling phenomena of membrane distillation in wastewater treatment and desalination. The design of membrane and its system from the perspective of material and process design were discussed to provide an insight on the current and future advancement in MD technology for water recovery. Finally, the future trend of MD is projected based on the state of the art development of MD process.
