The Elledge wastewater treatment plant is a 30mgd advanced wastewater treatment facility, which treats domestic and industrial wastewater. The effluent flow from the plant is discharged into the Salem Creek which eventually flows into the Yadkin River. Facilities were added to the Elledge plant in the early 1980’s to enable it to better meet nitrification needs. In the late 1980’s, odors became a major concern at the Elledge plant, requiring immediate action be the city. Improvements were made to the plant to provide odor control and upgrade/modernize the existing facility. In the late 1990’s, Biosolids became an issue, due to limited land availability and cost of land filling. Black and Veatch completed a study of solids disposal. This study resulted in a new dewatering facility. During this same time period a new aeration design for the activated sludge system was implemented to reduce over aerating, and to reduce energy needs. This was accomplished by a step feed design to “feed” organic loading across the entire activated sludge basins.
