Upscaling Reverse Electrodialysis [PDF]

open access: yesEnvironmental Science & Technology, 2018
Salinity gradient energy is a sustainable, renewable, and clean energy source. When waters with different salinities are mixed, the change in Gibbs free energy can be harvested as energy and only brackish water remains. Reverse electrodialysis is one of the technologies that can harvest this sustainable energy source.

Modern method of lactic acid recovery from fermentation broth

open access: yesCzech Journal of Food Sciences, 2004
Electrodialysis was used for lactic acid recovery from fermentation broth. In the first step, lactate was recovered and concentrated by desalting electrodialysis, and the second step was electroconversion of lactate to lactic acid by water-splitting ...

Finite elements-based 2D theoretical analysis of the effect of IEX membrane thickness and salt solution residence time on the ion transport within a salinity gradient power reverse electrodialysis half cell pair [PDF]

open access: yes, 2013
Reverse electrodialysis electrical power generation is based on the transport of salt ions through ion conductive membranes. The ion flux, equivalent to an electric current, results from a salinity gradient, induced by two salt solutions at significantly

Thermodynamic modeling of a combined photo-electrodialysis-chloralkali system for sustainable desalination

open access: yes, 2021
In this paper, a thermodynamic model of a combined photo-electrodialysis-chloralkali system for desalination is developed. The waste stream from an electrodialysis unit is sent to a chloralkali reactor, which produces several useful commodities namely ...

Fluorescence spectroscopy applied to the optimisation of a desalting step by electrodialysis for the characterisation of marine organic matter [PDF]

open access: yes, 2009
The isolation and characterisation of marine dissolved organic matter (DOM) are still not readily achieved today. The study of this chemically complex material is particularly difficult, especially as it is hindered by the high salinity of seawater.

Production processes of fermented organic acids targeted around membrane operations: design of the concentration step by conventional electrodialysis [PDF]

open access: yes, 2001
Organic acids are increasingly used for various industrial applications. Their production is mainly achieved by fermentation. Precipitation or extraction stages, which generate big amount of effluents, are then traditionally used to get the acid in a ...

Data on ion-exchange membrane fouling by humic acid during electrodialysis

open access: yesData in Brief, 2020
This data paper aims to provide data on the effect of the process settings on the fouling of an electrodialysis pilot installation treating a sodium chloride solution (0.1 M and 0.2 M) in the presence of humic acid (1 g/L).

Selective electrodialysis process for the recovery of potassium from multicomponent solution systems

open access: yesWater Science and Technology, 2023
Selective electrodialysis is a promising approach to recovering K+ from complex coexisting ionic systems. In this study, the effects of current density, the concentration of K+ and Mg2+, as well as the operating temperature on the separation process of K+

Understanding Membrane Fouling in Electrically Driven Energy Conversion Devices

open access: yesEnergies, 2021
Positively charged (cetylpyridinium chloride), negatively charged (sodium dodecyl sulfate), and non-charged (polyethylene glycol) surfactants are used as potential foulant in reverse electrodialysis systems supplying seawater and river freshwater ...
