Effluent (1.2 MGD) from an anaerobic digester was treated with ferric chloride to control sulfide. The ferric chloride treatment failed to sufficiently reduce hydrogen sulfide emissions (88% reduction) while simultaneously increasing TSS due to ferric sulfide formation. The ferric chloride was replaced with the AOTech process, yielding a 97% sulfide reduction while reducing TSS discharge concentrations by 27%. Treatment with the AOTech process provided control of hydrogen sulfide emissions while simultaneously reducing monthly TSS surcharges assessed by the municipal WWTP.
Anaerobic Digester Effluent – Industrial
Discover how an industrial anaerobic digester achieved 97% sulfide reduction and 27% TSS decrease, replacing ferric chloride with innovative AOTech treatment.
Condensate Underflow
AOTech process eliminated sulfide, thiol, and organic acid odors from a paper mill's 86,000 GPD condensate discharge, solving community concerns.
Industrial Effluent
AOTech technology improved industrial effluent treatment from 68% to 99% sulfide reduction, maximizing short retention windows.
