Wastewater treatment is a vital component in pulp and paper manufacturing. Most mills use direct-dive surface aerators in aerated stabilization basins (ASBs) to reduce biochemical oxygen demand and keep solids in suspension as the most economical equipment choice. This equipment often provides benefits like lower capital costs compared to other aeration equipment, no required permanent structure, and no need to dewater the basin for install.
But, there’s more to aeration than just installing the aerators and letting them run 24-7. A preventive maintenance program can optimize the life of the equipment. Here are some best practices to follow to get the most out of your direct-drive surface aerators, while reducing your operating costs.
