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

In a two-tank filtration system used for water treatment in hemodialysis, the first carbon tank is typically designated as the "Primary" carbon tank. This tank is crucial for the initial removal of contaminants, such as chlorine and chloramines, which are harmful to patients undergoing dialysis.

The primary carbon tank is specifically designed to significantly reduce the number of impurities in the water before it is sent to the second tank for further treatment. The proper functioning of this tank is essential for ensuring the quality of the water used in dialysis, thereby protecting the health and safety of patients.

Other designations like "Cleaner," "Worker," or "Handler" do not accurately describe the specific role of the first carbon tank in the filtration process and are not standard terms associated with this system.
