Ushering In A New Era Of Sustainable Biological Treatment
9/14/2021
Conventional activated sludge treatment for wastewater is becoming increasingly problematic over time. Not only does the process require significant amounts of energy, which drives up operating expenses, but utilities are under mounting pressure from the U.S. EPA to go green. Much of that push is focused on energy efficiency. Aqua-Aerobic’s AquaNereda® Aerobic Granular Sludge technology can help overcome these issues as well as other emerging constraints.
