Abstract Osmotic energy, existing between solutions with different concentrations, is a sustainable and ecofriendly resource for solving energy issues. However, current membrane-based osmotic conversion technologies focus on electricity generation from an “open” system by directly mixing salt (NaCl) at room temperature. For the integrated utilization of thermal higher power output performance, ...

Membrane distillation (MD), which can utilize low-grade thermal energy, has been extensively studied for desalination. By incorporating solar thermal energy, the solar membrane distillation desalination system (SMDDS) is a potential technology for resolving energy and water resource problems. Small-scale SMDDS (s-SMDDS) is an attractive and viable option for the production of fresh water for sm...

To improve the energy efficiency of membrane distillation (MD), localized heating feed-membrane interface is advantageous relative to bulk feed. This motivated current study, which targeted at developing a simple two-step way fabricating Laser-Induced Graphene (LIG) Janus for electrothermal distillation. Specifically, had an electrically conductive graphene side and polydimethylsiloxane (PDMS) ...

Providing clean water to a rapidly growing population is an issue that currently getting lots of attention offer sustainable solution for scarcity. Membrane distillation (MD) one the latest technologies provides great potential in treatment. Even though there tremendous amount research done during past two decades on membrane distillation, long-term use this process still restricted by fouling....

Solar-assisted distillation is considered promising to solve the freshwater supply for off-grid communities. In this work, a passive and flexible multistage membrane (F-MSMD) device devised produce via solar with latent heat of vapor condensation being recycled enhance its energy efficiency. By designing siphon effect, source water continuously wicked into evaporation layer concentrated brine f...

A multilayered microchip (25 x 95 mm) used for vacuum distillation is designed, fabricated and tested by rectification of a water-methanol mixture. The polymer chip employs a cooling channel to generate a temperature gradient along a distillation channel below, which is separated into a channel (72 microm deep) for liquid phase and a channel (72 microm deep) for vapor phase by an incorporated m...

Membranes. In their Research Article (e202206152), Jian Xue, Jürgen Caro, Haihui Wang et al. report a bioinspired Ti3C2Tx MXene-based ionic diode membrane for osmotic energy conversion with extraordinary rectification.

A new feasibility analysis methodology generalized from distillation is applied to membrane process. The model is formulated to depict the reactive liquid phase composition on the retentate side of membrane reactors. The effects of both chemical reaction and membrane mass transfer kinetics on the feasible products are elucidated by means of retentate phase diagrams and bifurcation analysis. In ...
