    High-flux water desalination with interfacial salt sieving

    Freshwater flux and energy consumption are two important benchmarks for the membrane desalination process. Here, we show that nanoporous carbon composite membranes, which comprise a layer of

    Reverse Osmosis RO Membrane: Types, Structures,

    The reverse osmosis RO membrane most widely used for desalination at present are composed of a semipermeable thin film (0.2 um), made of either aromatic polyamide (PA) or cellulose acetate (CA), which is supported by a 0.025- to 0.050-mm microporous layer that in turn is cast on a layer of reinforcing fabric (Fig. 1.1 for a membrane with an

    Polyethylene-supported high performance reverse osmosis

    N2 - A polyamide (PA) thin film composite (TFC) reverse osmosis (RO) membrane having high permselectivity and excellent mechanical/chemical durability was prepared using a polyethylene (PE) support. Although the PE support's uniform pores and high surface porosity are beneficial for enhancing membrane permselectivity, its intrinsic

    Nanocomposites for Improved Physical Durability of Porous

    A key milestone for this technology was the development of a reverse osmosis (RO) membrane in the late 1950s [4,5] using cellulose acetate, which showed high salt rejection and high fluxes and thus was promising for membrane seawater desalination process. RO technologies have been commercialized since 1964 . With continual development of other

    the RO concentrate through an additional process such as membrane distillation (MD) desalination technology [4,5]. Membrane distillation is a new seawater desalination technology, and its future is encouraging. The driving force for desalination is the difference in temperature either side of a membrane. Membrane distillation uses less energy, is

    Fabrication of a Desalination Membrane with Enhanced

    Biofouling is a major obstacle for the efficient and reliable operation of membrane-based desalination processes. Innovations in membrane materials and fabrication processes are therefore needed to develop antibiofouling strategies. In this study, we utilize the alignability of an emerging two-dimensional nanomaterial, graphene oxide (GO), to fabricate a desalination membrane with enhanced

    Flux and salt rejection enhancement of polyvinyl(alcohol

    1. Introduction. Reverse osmosis (RO) has globally emerged as a promising desalination technology with remarkable advances made in this field during the past few decades [, , ].With the ever increasing demand for potable water, and increased stress on reduced capital costs, RO membrane materials have always been a topic of experimental and computational research [4,5].

    High flux high-silica SSZ-13 membrane for CO2 separation

    The hydrothermal stability of the high-silica SSZ-13 membrane was evaluated by a long (220 h) CO 2 –N 2 separation test with a humidified (9.5 kPa H 2 O) feed mixture at 393 K and 0.6 MPa feed pressure. The permeance and selectivity were stable during this endurance test, underpinning the promise of high-silica SSZ-13 membranes for
