A portable system for treatment of liquids, gases, or both using precise energy separation (PES) is described herein. The system includes a power generation component which charges one or more energy storage units and powers the PES component of the portable system. The PES component includes one or more energy of dissociation sources and the energy storage units power the sources to provide an effective amount, intensity, and frequency of a promoter energy to specifically dissociate one or more target bonds of the target molecule present in contaminated liquids, gases, or both. Optionally, the energy stored in the system can act as a supplementary or back up power source.
