Abstract: Described herein are various methods, systems, and apparatus for reducing and eliminating, microbes, minerals, chemicals and biofilms from contaminated substances. A combination of oxidizing agents and radiation of certain wavelengths forming a synergistic reaction. The synergistic reaction generates EMODs, which are effective in reducing microbial count, unwanted mineral or chemical concentrations and eliminating or blocking biofilm formation, particularly in anaerobic environments. The synergistic reaction produces long lasting EMODs thereby creating a residual effect. This synergistic reaction has a relationship to EMOD creation and has a detrimental effect on microbial contamination (MC), mineral contamination (MINC), chemical contamination (CC), microbial influenced corrosion (MIC) and biofilm creation.

Abstract: A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.
