Electrodialysis (ED) is used to transport salt ions from one solution through ion-exchange membranes to another solution under the influence of an applied electric potential difference. This is done in a configuration called an electrodialysis cell.
The cell consists of a feed (dilute) compartment and a concentrate (brine) compartment formed by an anion exchange membrane and a cation exchange membrane placed between two electrodes.
In almost all practical electrodialysis processes, multiple electrodialysis cells are arranged into a configuration called an electrodialysis stack, with alternating anion and cation exchange membranes forming the multiple electrodialysis cells.
The electrodialysis process takes place inside the cell (stack). The solutions are circulated through the cells from a storage vessel. Each circuit needs a pump, a storage vessel and piping.
consist of sulphonated polystyrene, while anion-selective membranes consist of polystyrene with quaternary ammonia.
Plimmer offers high purification levels, combined with competitive initial costs, minimum maintenance, absence of chemical substances and extremely low energy consumption.
