Clean water obtained by desalinating sea water or by purifying wastewater, constitutes a major technological objective in the so-called water century. In this work, a high-performance reverse osmosis (RO) composite thin membrane using multi-walled carbon nanotubes (MWCNT) and aromatic polyamide (PA), was successfully prepared by interfacial polymerization. The effect of MWCNT on the chlorine re...
Nanoporous grapheme-based materials have been widely recognized as an emerging and promising membrane material or selective layer of membranes to be used in separation [1] and purification applications [2, 3]. For instance, a pioneered modeling work reported by Cohen-Tanugi and Grossman [4, 5] shows that a graphene sheet with subnanometer pores can provide superior water transport rate and high...
Scarcity of fresh water, forced many countries to get their water needs, or part it, by means saline desalination. Reverse osmosis (RO) systems are useful tools in this concern. In case the grid electricity is not available costly, photovoltaic (PV) power necessary derive RO systems. The present paper concerned with providing a methodology for complete sizing and design reverse (PVRO) system Eg...
Capacitive desalination is a promising desalination technique. A novel fl ow-through electrode architecture utilizes a newly developed porous carbon material to achieve dramatic improvements in desalination rate and salt concentration reduction. Image depicts a capacitive desalination cell with a fl ow-through architecture. Capacitive desalination (CD) is a promising desalination technique as, ...
Recent advances in the development of nanoporous graphene (NPG) hold promise for the future of water supply by reverse osmosis (RO) desalination. But while previous studies have highlighted the potential of NPG as an RO membrane, there is less understanding as to whether NPG is strong enough to maintain its mechanical integrity under the high hydraulic pressures inherent to the RO desalination ...
Nanoporous graphene (NPG) shows tremendous promise as an ultra-permeable membrane for water desalination thanks to its atomic thickness and precise sieving properties. However, a significant gap exists in the literature between the ideal conditions assumed for NPG desalination and the physical environment inherent to reverse osmosis (RO) systems. In particular, the water permeability of NPG has...
