Introduction: Retrofit vs Replace: Upgrading Aeration in Aging Aeration Basins For municipal and industrial wastewater treatment plants, the activated sludge process remains the workhorse of biological nutrient removal. However, the aeration systems driving this process typically consume 50% to 60% of a facility’s total energy budget. When evaluating Retrofit vs Replace: Upgrading Aeration in Aging […]
INTRODUCTION There is perhaps no scenario more frustrating for a wastewater plant operator or design engineer than an aeration basin that is visually boiling with air, blowers running at 100% capacity, yet the dissolved oxygen (DO) concentration refuses to climb above 0.5 mg/L. Aeration Troubleshooting: Low DO is a complex, multi-disciplinary challenge that forces utility […]
