To determine the total gallons per day (GPD) of sludge removed from a primary clarifier using a triple piston pump, one must consider the operational parameters specific to the pump and the wastewater treatment process. The parameters could include variables such as the diameter and stroke length of the pistons, the number of cycles per minute, and the density of the sludge.

A triple piston pump is designed to deliver a consistent and high volume of sludge efficiently. This type of pump can move a significant quantity of liquid due to its operational design, which uses three pistons working cyclically to ensure a continuous flow. The correct answer of 178,796 GPD reflects a calculation that takes into account these parameters and the expected efficiency of the pump.

When performing operational calculations, factors like pump efficiency, anticipated sludge density, and variations in flow rates due to influent conditions are crucial. Thus, the chosen answer not only represents a computation based on given parameters but also aligns with operational expectations for a primary clarifier.
