Nitrogen Removal At A Very Large Scale

Nitrogen removal standards are a pressing concern for meat and poultry processing plants. Historically, food processing plants discharging to public waterways or directly to publicly owned wastewater treatment plants have faced challenges in meeting effluent limitation guidelines (ELGs) for nutrient removal. That may soon become even tougher yet with the U.S. Environmental Protection Agency (EPA) announcing in September 2021 that it has completed a detailed study of the meat and poultry products category and will initiate new rulemaking to revise the existing discharge standards for the industry.
