The statement is false because the primary distinction between step-feed aeration and conventional aeration lies in the method of introducing influent wastewater into the aeration tank, not specifically in the way waste is added. Step-feed aeration strategically adds wastewater in sections or "slugs" to different parts of the tank, optimizing the aeration process and allowing for improved nutrient removal. On the other hand, conventional aeration typically involves a continuous, uniform inflow of wastewater.

Understanding this difference is crucial, as the design and operation of wastewater treatment systems can significantly affect their efficiency and effectiveness. While different tank sizes or operational conditions may influence how aeration is optimized, the fundamental characteristic distinguishing step-feed from conventional aeration is the way influent is introduced, rather than the mere fact of introducing waste in slugs.
