This is the first on site carbon regeneration system utilizing ozone technology for air and water. The system utilizes pretreatment steps to enhance VOC oxidation and carbon adsorption efficiencies. Due to blinding of the carbon from solids accumulation, the first carbon replacement since installation in 1988 was February, 1996. Activated carbon becomes a polishing media instead of the focus of treatment. This happens as the wavelength of light decreases or becomes shorter than that of visible light, the energy level of photons increases and initiates the breakdown of the molecular bond.
Ozonated water is recirculated in the scrubber to initiate the oxidizing of the contaminants.
Acids are controlled with a PH adjustment by introduction of caustic. At this stage, the species are mainly in the air phase and the treated water is passed through parallel carbon beds. At the second stage of the process, the air is passed through a patented photolytic reactor. These wavelengths of light must be mutually exclusive of one another in order not to interfere with each others wavelength since there are many different energy levels of chemical bonds with respect to photon absorbing electrons. The photons emitted from the UV lamps break apart the chemical bonds that make up the molecule.
