Ammonia removal and recovery from wastewater have been a critical issue worldwide and a
key to achieve a sustainable nitrogen cycle and circular economy. Conventional ammonia …

Usually in electrochemical systems, the direct current densities not exceeding the limiting
current density are applied. However, the recent practice of electrodialysis evidences the …

For about 60 years, it is known that “limiting current” density does not really limit the current
density in electrodialysis (ED). The use of intensive currents allows one to decrease the area …

Membrane capacitive deionization (MCDI) is an ion-removal process based on applying an
electrical potential difference across an aqueous solution which flows in between oppositely …

Electrodeionization is an ionic separation technology that initially emerged∼ 50 years ago.
In an early application, it was utilized to remove metallic species from radioactive …

We present a comprehensive analysis of transport processes associated with
electrohydrodynamic chaos in electrokinetic systems containing an ion-selective surface …

Transport of water through ion-exchange membranes is of importance both for
electrodialysis (ED) and reverse electrodialysis (RED). In this work, we extend our previous …

Bipolar ion-exchange membranes (BPM) have a long history and many uses. Still, the
number of applications continues to grow every year, as does the interest in a better …

An energy-efficient and reagent-free system consisting of ion exchange, bipolar membrane
electrodialysis and membrane contactor (IE-BMED-MC) was developed for recovering …

We present porous electrode theory for the general situation of electrolytes containing
mixtures of mobile ions of arbitrary valencies and diffusion coefficients (mobilities). We focus …
