Abstract
This invention refers to a removal and recovery method of pollutant materials. A waste stream source of polluted water and/or waste gases containing waste acids, bases and salts, and/or waste air pollutant suspension particles are fed into a separation reactor. The combined physicochemical effects of removal/recovery of pollutants inside the reactor take place by solubilization, ionization, reaction, deposition and settling, which concurrently remove and separate the pollutants as solid materials, deposited on selective electrodes sets, as gases and as sludge and/or precipitates. The reactor is kept at the working temperature using a waste industrial heat, and the separation processes take place by applying a voltage source between a spaced apart system of selective electrodes, and by using a ionizing source of waste spent fuel nuclear bars or electromagnetic radiation.
