Super Heated Water

Another method to remove PCB's from water is to use a super critical water oxidation, per the Organo company in Japan. This method completely decomposes PCB’s. Super critical water is water that is heated over 374 C (860 F), at an atmospheric pressure of 220. This super critical water has a super oxidation faculty, which can decompose Dioxin. This method is also non-chemical, avoids the possibility of fire, and the factory can drain the water when the process is complete without fear of polluting.

Mitsubishi Industrial company in Japan has an SRI thin tank patent in the USA for hot water dismantling of PCB’s. The reacting tower is maintained at 380 C, 270 atmospheric pressure. The technique is to put in the PCB polluted water with Na2Co3. Then put in O2 (Oxygen) and the PCB’s are dismantled. The catalytic-NaCo eliminates Cl from the PCB’s, so the NaCl step does not occur, dismantling Viphenyl at the same time.
