Thermally driven membrane desalination processes have garnered significant interest for their potential in the treatment of hypersaline wastewater. However, achieving high rejection rates volatiles while maintaining a water flux remains considerable challenge. Herein, we propose thermo-osmosis-evaporation (TOE) system that utilizes molecular intercalation-regulated graphene oxide (GO) as thermo-osmotic selective permeation layer, positioned on hydrophobic poly(vinylidene fluoride) fibrous serving thermo-evaporation layer. By carefully constructing architectural interlaminar nanochannels GO membranes via simultaneously confining small molecules to enlarge interlayer spacing and incorporating polymers within interlayers create dense network, resultant demonstrates rate 100% NaCl 97.41% volatile phenylamine, with permeance 63.80 L m-2 h-1 at temperature difference 40 °C, outperforming previously reported GO-based membranes. Simulation calculation results reveal polymer network between facilitates high-efficiency separation nonvolatile ions molecules, enlarged channels reduce vapor diffusion resistance. This study provides valuable insights design advanced serves inspiration continued development TOE complex wastewater treatment.

Surface Microstructure Drives Biofilm Formation and Biofouling of Graphene Oxide Membranes in Practical Water Treatment

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(27), P. 12281 - 12291

Published: June 28, 2024

Significant progress has been made previously in the research and development of graphene oxide (GO) membranes for water purification, but their biofouling behavior remains poorly understood. In this study, we investigated biofilm formation GO with different surface microstructures context filtering natural an extended operation period (110 days). The results showed that relatively hydrophilic smooth Fe(OH)3/GO membrane shaped a thin spatially heterogeneous high stable flux. However, ability to simultaneously mitigate reduce was not observed weakly wrinkled Fe/GO H–Fe(OH)3/GO membranes. Microbial analyses revealed hydrophilicity roughness distinguished bacterial communities metabolic functions. organic matter-degrading predatory bacteria were more adapted surfaces. These functional taxa involved degradation extracellular polymeric substances (EPS), improved heterogeneity. contrast, surfaces had reduced biodiversity, while unexpectedly boosting proliferation EPS-secreting bacteria, resulting increased aggravated biofouling. Moreover, all achieved sustainable purification during entire operating period.

Bubble Turbulent Gas-Permeable Membrane for Ammonia Recovery from Swine Wastewater: Mass Transfer Enhancement and Antifouling Mechanisms

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(13), P. 6019 - 6029

Published: March 21, 2024

Recovering ammonium from swine wastewater employing a gas-permeable membrane (GM) has potential but suffers the limitations of unattractive mass transfer and poor-tolerance antifouling properties. Turbulence is an effective approach to enhancing release volatile ammonia while relying on interfacial disturbance interfere with contaminant adhesion. Herein, we design innovative coupled bubble turbulence (BT-GM) that enhances mitigating fouling. Bubbles act as carriers accelerate migration liquid phase, increasing concentration gradient at membrane–liquid interface. In comparison, rate BT-GM process applied real 38% higher than conventional GM (12 h). Through computational fluid dynamics simulation, kinetic energy system 3 orders magnitude GM, area nearly times GM. Seven batches tests confirmed exhibits remarkable ability, broadens its adaptability complex water quality, practically promotes development sustainable resource recycling.
