Wastewater Treatment
Control and optimisation of a high strength nitrogen industrial wastewater BNR plant
10/08/2010
Meat rendering plants produce very high strength nitrogenous wastewater that requires intensive monitoring and control to ensure adequate nitrogen removal. A North Island based rendering plant that produces meat & bone meal, tallow and blood products, with raw wastewater nitrogen concentrations of 730 mg/L, found that its biological nitrogen removal (BNR) part of the wastewater treatment plant was operating poorly, generating a lot of odour and was not meeting the discharge consent compliance limits.
