The primary function of carbon tanks in the pre-treatment process is to filter out chlorine and chloramines from the water used in hemodialysis. Chlorine and chloramines are commonly used as disinfectants in municipal water supplies. However, in the context of hemodialysis, these substances are harmful as they can damage red blood cells and interfere with erythropoiesis.

Carbon tanks utilize activated carbon, which is highly effective at adsorbing these chemicals due to its large surface area. As water passes through the carbon tank, chlorine and chloramines adhere to the surface of the carbon, effectively removing them from the water before it reaches the dialysis equipment. This is a critical step in ensuring that the water quality meets the stringent standards required for safe dialysis treatments.

The other functions mentioned do not align with the role of carbon tanks. Heating water is typically handled by other components in the dialysis system, increasing mineral content is not a goal in the context of dialysis since pure water is preferred, and softening hard water involves ion exchange processes that are different from the adsorption principles utilized in carbon tanks.
