“…Graphene oxide membranes were discussed in detail as an AM material for both terrestrial and space‐born water purification applications. [ 168 ] AM tests on common E. coli and P. aeruginosa bacteria on GO resulted in reduced survival rates of 11.8% and 11.9%, respectively. [ 169 ] Furthermore, GO was proven to effectively eradicate P. aeruginosa , [ 170 ] which is a multidrug resistant pathogen found inside the ISS (Table 1).…”

An overview of the current surface treatments/coatings that introduce antimicrobial properties to the exposed surfaces in confined space stations is provided. General aspects, such as biofilm formation and the specific requirements associated with this application, are discussed. Antimicrobial coatings used on the International Space Station (ISS) are reviewed. A selection of commercial and developed coatings targeting space applications is presented. Also, some developments that can be used in the space industry are highlighted.

“…GO nanosheets were deposited via an LBL assembly approach on polydopamine-coated polysulfone support and then cross-linked by 1,3,5-benzenetricarbonyl trichloride (TMC) providing a 58% salt rejection with 93.84 L m À2 h À1 bar À1 . 91,92 The properties of the substrates showed to have a remarkable inuence on the adhesion and transport of GO membranes. In particular, the morphology and the chemical structure of the surface of the substrate permit the GO assembly and adhesion, while the pore structure of substrates governed the GO membrane transport resistance.…”

“…Maddah et al (2018) used PVDF (FP100), PES (ES404), besides low (AFC40)-and high (AFC99)-pressure PA commercial membranes for the treatment of red seawater at Rabigh City (Maddah et al 2018). Graphene oxide membranes were used for enhancing the water purification in terrestrial and space applications by Buelke et al (2018). Most of the production of commercial membrane in the form of large flat sheets without substantial defects is extremely difficult, especially if additives such as graphene oxide are used and it needs tremendous efforts to bring these membranes to market at low cost.…”

Modification of used commercial reverse osmosis membranes to nanofiltration modules for the production of mineral-rich packaged drinking water

et al. 2020

Global supply of commercial reverse osmosis (RO) membranes is growing exponentially due to rapid population growth, industrialization, and urbanization. The continuous demand for enormous quantity of drinking water has brought about process improvements and technological advancements in membrane preparation. The transformation of used RO membranes into nanofiltration (NF) and ultrafiltration membranes by opening up the pores using chemical treatment by inexpensive oxidizing agents could be one of the cost-effective options. The present study investigates the chemical oxidation of the indigenously synthesized RO membrane using aqueous sodium hypochlorite (NaOCl). The performance of the membrane was evaluated by conducting experiments under varying operating conditions of operating time, feed pressure, and total dissolved solids (TDS) in raw water for calculation of flux and salt rejection (%). From an initial flux of 25.2 L/m2 h and TDS rejection of 97.5% for original RO membrane, the values reached 80 L/m2 h and 25.5%, which is in NF range, after a reaction time of 780 min with 4000 ppm concentration of NaOCl oxidizing agent. Further extension of treatment time to 900 min enhanced the flux to 130 L/m2 h with salt rejection lowering to 5.67%. Membrane cleaning was performed efficiently using an advanced technique in which chlorine dioxide (ClO2) was used in combination with citric acid. This combination ensured rapid cleaning with restoration of water flux and % salt rejection. The process was scaled up to pilot plant level using RO membranes modified to NF range of pore size. Permeate water enriched with minerals was further packed using an indigenously designed semi-automatic bottling unit. The studies revealed that the indigenously developed RO membranes are easy to alter into high-performance NF membranes. Overall, the process for production of packaged drinking water was cost-effective, easy to operate, and environmentally friendly.
