Sprague Sanford, Inc. is a manufacturer of electronic components in southern Maine. Part of their process requires the use of ethylene glycol. Sprague wanted a new system to dependably address this waste stream while avoiding the high costs and uncertainty they were facing. A characterization study revealed that approximately 100 gallons per day at 350,000 mg COD/L needed to be handled by the new system. Nearly all of the COD present was as waste ethylene glycol solvent. However, product quality concerns made recovery and reuse of this waste stream too difficult. A wastewater treatment technology screening and economic analysis indicated that the upflow anaerobic sludge blanket process (UASB) was well suited for this application. This paper describes the UASB system, initial start-up, initial results and problems, potential causes, corrective actions, restart of the system, and current performance results.
