Using ATP in Suspended Growth Wastewater Treatment Systems – What is the benefit?
Suspended growth systems, such as activated sludge, are a very common form of secondary wastewater treatment. The potential to optimize and improve the operation of such treatment plants using ATP is tremendous. ATP can directly quantify active biomass, which is key to providing secondary treatment. Two of the many potential uses for ATP in… Read More
