Starting with a product in mind – biosolids management design based on beneficial use goals

Biosolids generators across the United States are beginning to reevaluate their processing and management programs, to consider new technologies and products. As part of this, they are considering new regulatory requirements, more flexible outlets, and the concept of biosolids as a product. Their focus is no longer technology centered, but rather on product quality and the best use for it. As part of their Long-Term Biosolids Master Planning effort, Howard County Department of Public Works fulfilled their goal of selecting a solids processing technology that reduces volume and generates a Class A exceptional quality biosolids product that could be use locally in agricultural or non-agricultural markets. In this case, product quality characteristics were important in entering local markets. Key aspects of the selection process are discussed, including establishing County goals, identifying and surveying local beneficial use markets, selecting a solids management alternative, and ultimately selecting the dryer technology fulfilling the County's objective.
