What is the designation of the first carbon tank in a two-tank filtration system?

In a two-tank filtration system, the correct designation for the first carbon tank is typically referred to as the "Primary" tank. This tank is the first stage in filtering out impurities from the water supply before it enters the dialysis machine. The primary tank's main purpose is to capture larger particulates and provide a first line of defense against contaminants, ensuring that the water quality meets the necessary standards for safe patient treatment.

The use of the term "Primary" indicates its essential role in the filtration process, as it sets the stage for the second tank, which may have a different function or serve as a backup. Understanding the role of the primary tank is crucial for ensuring proper system maintenance and water safety in hemodialysis procedures.
