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

The designation of the second carbon tank in a two-tank filtration system is known as the "Polisher." In hemodialysis, a two-tank system often utilizes the first carbon tank to remove larger contaminants and impurities from the water supply. The second tank, referred to as the polisher, serves to further refine and enhance the purity of the water. This step is crucial because the water quality directly impacts patients' safety and the overall effectiveness of the dialysis process.

By using a polisher, additional treatment occurs to ensure that any remaining contaminants are minimized, allowing for the production of high-quality water that meets strict standards for use in dialysis. Therefore, the polisher plays a vital role in ensuring the water is sufficiently treated before it is used in the dialysis machines.
