What are the two types of di tanks used in dialysis?

The correct answer identifies the two types of DI (deionized) tanks used in dialysis as dual bed and mixed bed. A dual bed system typically consists of two tanks that separately contain different types of resin: cation resin and anion resin. This configuration allows for more efficient and effective removal of ions from the water, ensuring that the water used in dialysis is purified to meet safety standards.

On the other hand, a mixed bed system combines both cation and anion resins in a single tank. This design can also effectively deionize water but may have different operational characteristics and regeneration needs compared to a dual bed system. The choice between these two types typically depends on the specific requirements of the dialysis facility and the water quality needed for treatment.

Understanding these distinctions is crucial for ensuring the safety and effectiveness of the dialysis process, as the quality of water is fundamental to patient care and dialysis outcomes.
