    Over $10 million dollars was saved, by an Ohio meat processor, by treating their wastewater in a new way. A sand bioreactor system was developed based on research conducted at The Ohio State University. This university-industry partnership has saved jobs, money, and is protecting the environment with effluents exceeding the quality of conventional treatment systems. Regulators, designers, food processors, and installers will learn about the development of a low-cost system for treating high-strength wastewater. The highlight of the workshop is a tour of the treatment system.
