Question: 1 / 400

To prevent bacterial growth in the water of the product water distribution loop, what should the flow rate be?

2-Feet per second

3-Feet per second

The ideal flow rate in the product water distribution loop is crucial for preventing bacterial growth and ensuring that the water remains clean and safe for dialysis procedures. A flow rate of 3 feet per second is effective because it creates enough turbulence within the system to reduce stagnation, which is a primary contributor to bacterial growth. Maintaining this rate helps to flush out bacteria and other contaminants in the water, promoting a continuous and thorough circulation that is vital for the health and safety of patients undergoing hemodialysis.

A flow rate that is too low may result in stagnant water areas where bacteria can multiply, while significantly higher flow rates could lead to increased wear on the system components without providing additional benefits in preventing bacterial growth. Thus, the specified rate of 3 feet per second strikes an appropriate balance for maintaining a hygienic environment in the water distribution loop.
