In the activated sludge process, what does the term "loading" refer to?

Volume of water entering the system
Pounds of CBOD entering the aeration tank
Amount of oxygen supplied to bacteria
Rate of sludge return to the aeration tank

The correct answer is: Pounds of CBOD entering the aeration tank

In the activated sludge process, "loading" specifically pertains to the pounds of carbonaceous biochemical oxygen demand (CBOD) entering the aeration tank. This measurement is crucial because it reflects the amount of organic matter present in the wastewater that needs to be treated. The higher the loading rate, the more organic material is available for the microorganisms to consume, which directly influences the efficiency and performance of the treatment process. Understanding the loading is essential for operators to manage treatment conditions effectively, as it can impact factors such as the required aeration time, the amount of biomass in the system, and the overall treatment efficiency.
