STM-Aerotor™ Biological Nutrient Removal
Available from WesTech Engineering Inc
The STM-Aerotor™ Biological Nutrient Removal (BNR) Package Plant uses Activated Sludge and Fixed Film technology as part of a process that provides biological nutrient removal for municipal wastewater treatment.
WesTech Engineering has incorporated the STM-Aerotor IFAS technology into modular package wastewater treatment plants. The fixed film and activated sludge combination allows the STM-Aerotor to accomplish a high level of treatment in a small tank volume. In addition, the unique aeration device of the STM-Aerotor decreases the installed HP requirement saving in overall operational costs.
