- Abstract
- An electrochemical process has been developed for destroying organic compounds dissovled in water. This process utilizes novel electrodes that generate hydroxyl free radicals. Hydroxyl attacks most organic compounds in a nonspecific manner. Phase 1 work showed that the process easily destroys the foaming ability of aqueous film-forming foam. Aromatic hydrocarbons and phenols derived from jet fuel are destroyed extremely well, due to favorable reaction kinetics and excellent mass transfer in the prototype treatment unit. A detailed conceptual design and cost estimates for a full-sized mobile water treatment unit indicate that the process will be cost effective for treating waste water from firefighter training and hanger fires. For example, a 30 gpm production unit is projected to cost about $185K to procure and could treat the waste water from a large hanger fire in 22 hours at a total cost of $2,900 including labor and amortization.
