Abstract
The present application is directed to a method of remediation of contaminants through the formation of a treatment zone defined by an introduction of biochar, an aerobic contaminate degrading bacteria, and sufficient oxygen sources to maintain aerobic conditions for contaminant degradation by microbial activity in the treatment zone. The present application may be applied to in situ or ex situ contaminant remediation.
Claims15
A method of contamination remediation comprising the steps of:
- forming a treatment zone in a contaminated area containing an initial concentration of a perfluoroalkyl and/or polyfluoroalkyl substances (PFAS) and/or a perchloroethylene (PCE) contaminate, the treatment zone defined by an introduction of treatment slurry comprising biochar and an aerobic contaminate degrading bacteria additive;
- supplying the treatment zone with an oxygen source:
- concentrating the contaminate at the surface of the biochar located in the treatment zone;
- and,
- degrading the contaminate at the surface of the biochar with the aerobic contaminate degrading bacteria additive to generate a final concentration of the contaminate that is less than the initial concentration.

A system for use in the remediation of an organic contaminant comprising:
- a treatment application having:
- a biochar formed of a plurality of particles having a net surface area of greater than or equal to 900 square meters per gram and less than or equal to 1,500 square meters per gram, wherein the particles have a particle size of between 0.5 microns and 4000 microns,
- an aerobic contaminate degrading bacteria selected from a group consisting of Pseudomonas, Rhodococcus, and Pseudonocardia, Bacillus, Actinomycetota, combinations thereof,
- an oxygen source selected from a group consisting of peroxygens and/or oxygen electrically generated via electrodes placed within a treatment zone, air sparging, gas diffusion or a combinations thereof, wherein the oxygen source is configured to maintain aerobic conditions in the treatment zone;
- and
- wherein the treatment application is configured to degrade an initial concentration of a perfluoroalkyl and/or polyfluoroalkyl substances (PFAS) and/or a perchloroethylene (PCE) contaminate in the treatment zone to a final concentration that is less than 5% of the initial concentration.
