Abstract

A decontamination system includes a spraying system in an enclosed chamber for application of a decontamination fluid having a liquid carrier, such as water, and an enzyme-based decontaminating chemical additive. The additive contains an organophosphorus compound-degrading enzyme. The decontamination system also includes a fluid flow control system that ensures delivery of decontamination fluid to spray nozzles. The fluid flow control system features a recirculation system that collects runoff from the chamber and transports the collected runoff to a decontamination reactor. The decontamination reactor removes contaminants from the collected runoff liquid and permits the collected runoff liquid to be reused for further decontamination, thus taking advantage of the catalytic characteristic of the enzyme.

Dependent claims

A decontamination system for an object, comprising:

a supply of a decontamination fluid, the decontamination fluid comprising:
a liquid carrier;
and
a decontaminating chemical additive mixed with the liquid carrier, the decontaminating chemical additive comprising an organophosphorus compound-degrading enzyme;
and
a liquid applicator operatively associated to the supply of the decontamination fluid, wherein the liquid applicator applies the decontamination fluid to the object to be decontaminated;
a decontamination fluid flow control system for conveying the decontamination fluid from the supply of the decontamination fluid to the liquid applicator, wherein the decontamination fluid flow control system comprises:
a recirculation system for recovering decontamination fluid for re-use after application by the liquid applicator, wherein the recirculation system comprises:
a liquid collector that collects the decontamination fluid after application by the liquid applicator;
a fluid conduit that conveys the collected decontamination fluid from the liquid collector;
a decontamination reactor that:
receives the collected decontamination fluid, and detoxifies a contaminant in the collected decontamination fluid;
an analyzer operably associated with the detoxified decontaminated fluid to determine a level of residual contamination in the detoxified decontaminated fluid;
a waste container for decontamination fluid;
a fluid flow control device to selectively direct the detoxified decontaminated fluid to at least one of the liquid applicator and the waste container;
a fluid conduit for conveying the detoxified decontamination fluid to at least one of the liquid applicator and the waste container;
and
a plurality of pumps operatively associated with one or more of the liquid collector, the fluid conduit that conveys the collected decontamination fluid from the liquid collector, the decontamination reactor, the analyzer, the fluid flow control device, and the fluid conduit for conveying the detoxified decontamination fluid, wherein the pumps provide impetus to flow decontamination fluid through the recirculation system.
