Description:
This study presents the sampling and analysis results for the characterization of liquid effluents and solid residuals from a culled potato feedstock process for the production of ethanol for use as fuel. The facility tested produces approximately 1 million gallons per year of ethanol and is located in eastern Idaho. Liquid and solid samples were taken throughout the process from the following locations: sluice/flume water, chopper product, makeup water, cooker product, fermenter product, beer tank, stillage, interim and final product, washwater, fusel oil, bath and 'Sparkle' bath. Analytical results for the ethanol plant effluents include: ethanol and sugar content, conventional parameters, metals, cyanide, phenols, nutrients, oil and grease, priority pollutant organics, and selected pesticides. The most significant characteristics of concern were the BOD and COD levels.
