Section 4. FOOD WASTES AUTOMATIC RESPIROMETRY-A UNIQUE TOOL FOR DETERMINING DESIGN PARAMETERS FOR A CANNERY DOMESTIC WASTEWATER TREATMENT PLANT Robert M. Arthur, President Lawrence W. Kent, Project Engineer Roccy J. Raymond, Project Engineer Arthur Technology, Inc. Fond du Lac, Wisconsin 54935 INTRODUCTION The Village of Eden, Wisconsin, will soon be constructing new wastewater treatment facilities to serve the community for the next 20 years. During the planning process it was determined that the canning company in the village was in need of additional treatment capacity for wastewater generated during their pea and corn canning operations. The canning company asked that capacity for their wastewater be designed into the new municipal treatment facilities. The canning company presently utilizes three lagoons for storage and anaerobic treatment of their wastewater (See Figure 1). The primary method of disposing of the wastes is to retain the water in the lagoons during the winter and discharge to a stream in the springtime when BOD has been reduced to an acceptable level, as determined by the Wisconsin Department of Natural Resources. The amount of discharge is supposed to be controlled by DNR according to the BOD5 of the waste and the river conditions during the springtime. A secondary method of disposal is by spray irrigation of wastewater to cropland. Much of the land in the Eden area is not suitable for this type of disposal because of high seasonal groundwater and high bedrock.
