The present invention is for an improved vertical flow reactor utility that makes the technology more attractive for industrial development. The various embodiments of the invention improve various aspects of a vertical flow reactor utility. For example, in accordance with an embodiment of the invention, the design of the reactor is improved. Other embodiments provide improved systems and methods for, for example, insertion of oxygen, electrical production, and/or reactor geometry. These one or more various embodiments of the present invention lowers costs to construct, install, and/or operate a vertical flow reactor by improving economy of construction and/or operation of VFR systems.

Compositions and methods for oxidizing organic contaminants while sequestering inhibitory forms of carbon. An oxidant capable of producing free radicals oxidizes organic contaminants. A metal oxide, metal hydroxide, or metal peroxide generates a soluble hydroxide concentration of about 1×10.sup.−4 M or greater to convert carbonic acid, bicarbonate ion, methane, elemental carbon, and other organic forms of carbon to carbonate ion. A metal having a carbonate with a lower solubility product constant than its hydroxide precipitates the carbonate ion as a metal carbonate, thereby eliminating soluble carbonate as a radical scavenger. Compositions and methods that additionally minimize metal solubilization and sequester solubilized metals are also disclosed.
