Novel System for the Decontamination of Firefighter Training Facility Wastes

摘要

High foaming potential and chemical oxygen demand restricts discharge of firefighter training waste waters. Innovative BioSystems designed a novel low energy bioreactor for application to firefighter training wastes. Jet A fuel concentrations went down. Concurrently, the butyl carbitol was transformed and more slowly degraded. In another reactor BTEX levels fell: from initial values of 150 ppm to less than 4 ppm within 20 days. IBS AFFF at 0.3% concentration was degraded with surface tension measurements increasing from about 12 dynes/cm to over 30 dynes/cm within the first 10 days of degradation. The IBS AFFF shows promise as a more degradable surfactant that should cause fewer problems in wastewater treatment facilities. Butyl carbitol is not a good choice as an AFFF co-solvent, and reducing the concentration in AFFF formulations would improve biodegradation and toxicity in degrading fuel components in firefighter training waste waters.
