Wastewater treatment system evaluation of a rapidly changing industrial FOG wastestream / by Christopher A. Loney. by Loney, Christopher A.

Contents:  Wastestream History -- Project Scope -- FOG Pretreatment System Components -- FOG Treatment Methods -- Inorganic Chemistry -- Organic Chemistry -- Process Technology Review -- Construction and Engineering -- Risk Analysis -- Recommended Technology -- Bibliography -- References The S.C. Johnson & Son, Inc., Racine WI, manufacturing facility had constructed a wastewater pretreatment system in 1995 to remove fats, oils and grease (FOG), a major component of EDGETM and SKINTIMATETM shave product manufacturing. The FOG wastewater pretreatment system efficiency was reduced in spring of 1997 caused by the reformulation of the shave products. In 1997, the system was upgraded from using acidification to cationic polymers to resolve the polar surfactant negative charge. Historical data show many reformulated products and the introduction to new products that contribute to this wastestream challenging the FOG pretreatment system to maintain performance. The system is required to remove +95% of the FOG and COD, resulting in frequent technology review and one system upgrade. This report identifies six FOG pretreatment systems, which have all proven to effectively remove these pollutants. A complete financial analysis was used to identify which system is best for S.C. Johnson. This report itemizes annual operation expenses, maintenance costs, disposal reduction, utility consumption, risk assessment, and safety issues during operation. An option will be selected based on the itemized criteria and recommended as the best value for treating this wastestream.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .L667 2000 Available Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
