Abstract: A method of degrading organic contaminants includes pre-treating the organic contaminants with an oxidizing promoter of in situ surfactant formation, extracting the organic contaminants with isopropanol (IPA) followed by treatment with UV to dechlorinate PCBs and degrade biphenyls. A photoreactor uses a plastic coil in a flow through configuration, with six UV lamps, of which five are around the coil and one at the center. The photoreaction using the photoreactor is fast and efficient.

Abstract: The present invention uses a dessicant and a means of drying out or changing the system by the use of off-peak electric power releasing. The heat is then released as required during periods of peak electric power by the reintroduction of moisture. The system includes a source of air and a fan for circulating the air in a circulation system including an outgoing loop and return loop for the circulating air. Selectively operatable evaporator heat exchanger, air wetting apparatus, and air heating apparatus are disposed in the outgoing loop of the circulating air. A dessicant-containing enclosure used to provide heat storage, and having air inlet means thereinto from outgoing loop the circulating and an air outlet means therefrom to the return loop of the circulating air is disposed in the circulation system.
