Utilization of Reverse Electrodialysis Processes for the Abatement of Pollutants in Water

open access: yesChemical Engineering Transactions, 2014
The simultaneous generation of electric energy and the treatment of waters contaminated by Cr(VI) was carried out by reverse electrodialysis processes using salinity gradients. The effect on the process of the nature of the cathode was investigated.

Environmentally-safe anion exchange membranes of PVA/PDDA/SiO2composite for reverse electrodialysis

open access: yesInternational Journal of Thermofluids, 2023
Anion Exchange Membranes (AEMs) are positively charged polymer membrane used in many applications. In RED systems, AEMs could be used to separate ions to produce energy, and on the other hands remove unwanted molecules in wastewater.

Electrochemically induced precipitation enables fresh urine stabilization and facilitates source separation [PDF]

open access: yes, 2020
Source separation of urine can enable nutrient recycling, facilitate wastewater management, and conserve water. Without stabilization of the urine, urea is quickly hydrolyzed into ammonia and (bi)carbonate, causing nutrient loss, clogging of collection ...
