Zapping toxic organics
The high reactivity of the electron and its potential for generating highly oxidising species which can break down toxic organics is an area which has been extensively studied by EA Technology.
Electrode coating and membrane technologies used in the DEM cell allow higher current densities than those applied in traditional parallel plate cells, resulting in greater electrical effect. The reduction in the electrode gap provides uniform flow characteristics with resulting high mass transfer, thus maximising reactivity.
The design of the cell means that the material of construction for the individual components can be chosen for optimum compatibility with the liquids being used. Waste streams already successfully treated using this technology include ammonia, organocyanides, phenols, amines, nitro-compounds and aliphatic chlorocompounds.
