Ammonia Reduction By Bioremediation

Specially selected microbes treat poultry processing wastewater to reduce nitrogen and organic waste levels

Petrox DN organisms reduced ammonia-nitogen  and BOD levels in the same wastewater reactor.  The organisms in Petrox removed 40% of the ammonia-nitrogen in 48 hours.  This reduction stabilized the concentrations in wastewater effluent to an acceptable level eliminating permit exceedances.

1,1,1-TCA Bioremediation at an Industrial Site in Dayton, Ohio

CL-Out bioremediation reduced the concentration of 1,1,1-TCA in ground water at a steel manufacturing facility in Dayton, Ohio. Following implementation of ozone treatment and high vacuum extraction for more than 2 years, the contaminant concentrations remained high.  Bioaugmentation followed up on these treatments and reduced the 1,1,1-TCA concentration very quickly.  Within 30 days of bioaugmentation, the source area contaminant concentration decreased by 80%.  After a second application, the concentration decreased from the pre-treatment concentration of 1,100 ug/L to 1.4 ug/L.  The bioaugmentation effect was observed as far as 250 feet downgradient where the concentrations decreased by more than 50%.  Click here for the full case study.

Aerobic Cometabolism of Chlorinated Solvents, Central New Jersey Case Study

CL-Out® was successfully used to remediate solvents in ground water at an operating industrial site in central New Jersey.  The the facility was a manufacturing and plating company with historical petroleum and solvent releases.

Chlorinated solvents were found in the ground water in two plumes covering a combined area of about one half acre.  The contaminants were a mix of chlorinated solvents including 1,1,1-TCA, 1,1-DCE and PCE in low concentrations.    The remediation goal was to reduce the mass of contamination in the ground water plume to prevent mitigate off-site risks.

After the CL-Out application, ground water concentrations in all monitoring wells decreased by more than 80%, which was sufficient to meet the remediation standards.  Click here to download a complete case study.

In-situ Bioremediation of BTEX, TPH and PAHs in Groundwater

Convenience Store in Florida

After three underground storage tanks were removed from the location of a convenience store, investigation showed that petroleum contamination was present in small area near the former dispenser island.  The vadose-zone contaminated soil was excavation and disposed off-site.  Ground water monitoring showed that the ground water impact was limited to a small area near the source of contamination. The decision was made to close the site by applying Petrox® bioremediation to the ground water.

Ground Water Contamination

The ground water contamination was in a shallow water table aquifer that had a medium permeability.  The contamination was a suite of BTEX, PAHs, methylnaphthalene isomers and TRPH.

Bioremediation

A pilot study was completed to determine feasibility of Petrox bioremediation combined with a peroxide oxygen supplement.  The pilot study reduced contaminant concentrations by up to 92%.  A full-scale application completed the site remediation.

Results

The pilot study and full-scale applications of Petrox and an oxygen supplement reduced BTEX compounds by >99%, naphthalene by 99%, TRPH by 96% and naphthalene isomers by 88% to achieve the remediation goals and site closure.  The microbial cost for the pilot study and full-scale treatment was less than $2,000.
