Industrial effluent (3.3 MGD) discharged to a municipal WWTP was being treated with a liquid oxygen diffusion system for sulfide control. The liquid oxygen system was unable to control the sulfide in the short retention time available (68% reduction).
The AOTech process was introduced to boost reaction rates, resulting in a 99% reduction in sulfide concentrations.
AOTech’s advanced oxidation process elevated sulfide removal from 68% to 99% within the same constrained retention time that had limited the existing liquid oxygen diffusion system. The dramatic performance improvement was achieved without modifications to the WWTP’s infrastructure or flow regime, demonstrating AOTech’s ability to boost reaction kinetics where conventional oxygen-based systems reach their ceiling. For a 3.3 MGD industrial discharge, the result was a treatment outcome that met municipal acceptance thresholds and reduced the risk of downstream process upsets and regulatory exposure for both the industrial discharger and the receiving facility.
