Data Based Management of an Odor Control Program – A Case History in Program Improvement

The Sanitation District 1 (SD1) located in northern Kentucky changed the structure and nature of the odor control program with positive results. A disciplined and data based odor control program was implemented in 2005. A supplier was selected to supply an odor control program and deliver results at various control points versus fragmented purchasing of products and technologies. Data is rigorously collected at each control site on a monthly basis and reported to SD1 by the odor control suppler. SD1 uses the data including hydrogen sulfide vapor concentrations to optimize the chemical addition program. The rigorous and data based approach to odor control has resulted in several positive benefits to SD1 as follows:Better customer service – SD1 has logged significantly less odor complaints from over 50 in 2004 trending less than 10 for 2006 (2 to date).Improved trend in chemical control – SD1 has measured significant improvement in quantity of chemicals used on a daily, monthly and annual basis by 25% (Jan-May 2006)Better performance from chemical purchased – Lower concentration of hydrogen sulfide is emitted.Teamwork and accountability from the supplier – Supplier is involved in the odor complaint response process.Improved program management – Proactive ability to forecast seasonal hydrogen sulfide loading and make adjustments to prevent hydrogen sulfide emission.This work will elaborate on the methods used and measurable results generated from the approach to odor control utilized by SD1.
