Robust membrane hydrophobicity is crucial in distillation (MD) to produce clean water, yet challenged by wetting phenomenon. We herein proposed a robust superhydrophobization process, making use of carbon nanotube (CNT) intermediate layer over commercial hydrophobic membrane, indirectly grafting the low-surface-energy material 1H,1H,2H,2H-perfluorodecyltriethoxysilane (FAS), with achieved denoted as PVDF-CNT-FAS, systematic comparison direct FAS on alkalinized PVDF PVDF-OH-FAS....
This work proposed an innovative and energy-efficient Donnan Dialysis (DD) Osmotic Distillation (OD) hybrid process for alkali-driven ammonium recovery from wastewater. The efficiency feasibility of removal synthetic real wastewater using NaOH waste alkali were investigated. Ammonium in the feed first transported across cation exchange membrane accumulated receiver chamber. It is then deprotonated as ammonia, passing through gas permeable finally fixed salt acid Our results indicated that...
The fouling/wetting of hydrophobic membrane caused by organic substances with low-surface energy substantially limits the development distillation (MD) process. sulfate radical (SO4 ·-)-based advanced oxidation process (AOP) has been a promising technology to degrade organics in wastewater treatment, and peroxydisulfate (PDS) could be efficiently activated heat. Thus, hybrid MD-AOP via PDS hot feed was hypothesized mitigate fouling/wetting. Experiments dealing sodium dodecyl (SDS)...
Membrane distillation (MD) theoretically intercepts salts completely and provides a promising desalination pathway for freshwater supply. However, conventional hydrophobic membranes fail to desalinate water containing surfactants or supersaturated gypsum over long term. To address wetting scaling challenges, we developed superhydrophobization methodology poly(vinylidene fluoride) by in situ controlling spherulitic surface morphology thermally induced phase separation. The major advantages of...
