Abstract
Enhanced contaminant degradation systems via rapid transfer of electrons in an environment or matrix through bioelectrochemical electron transfer circuitry, electron transfer conduit and conductive materials. Specialized circuitry may be used with respect to the anode, cathode, and transmission line design including floating cathodes, anchored anodes, and the like.
Claims30
A method of enhancing remediation of contaminated matrices comprising the steps of:
- providing an environment having at least one contaminant and at least one microbial population;
- providing a bioelectrochemical electron transfer circuitry having at least one anode, at least one cathode and at least one transmission line connecting said at least one anode and said at least one cathode;
- installing said bioelectrochemical electron transfer circuitry in said environment having said at least one contaminant;
- generating rapid transfer of electrons from said environment to said at least one anode of said bioelectrochemical electron transfer circuitry and said at least one cathode of said bioelectrochemical electron transfer circuitry through said at least one transmission line of said bioelectrochemical electron transfer circuitry;
- stimulating said at least one microbial population with said rapid transfer of electrons from said environment to said at least one anode of said bioelectrochemical electron transfer circuitry and said at least one cathode of said bioelectrochemical electron transfer circuitry through said at least one transmission line of said bioelectrochemical electron transfer circuitry to provide at least one stimulated microbial population;
- and
- substantially ameliorating microbial biodegradation of said at least one contaminant in said environment with said at least one stimulated microbial population.

A contaminant remediation enhancement system comprising:
- an environment having at least one contaminant and at least one microbial population;
- a bioelectrochemical electron transfer circuitry installed in said environment, wherein said bioelectrochemical electron transfer circuitry comprises at least one anode connected to at least one cathode through at least one transmission line;
- a rapid electron transfer movement from said environment to said at least one anode and said at least one cathode through said at least one transmission line of said bioelectrochemical electron transfer circuitry in said environment;
- at least one stimulated microbial population responsive to said rapid electron transfer movement from said environment to said at least one anode and said at least one cathode through said at least one transmission line of said bioelectrochemical electron transfer circuitry in said environment;
- and
- a substantially ameliorated microbial biodegradation of said at least one contaminant in said environment.
