a dialysis water distribution system?
Low water temperature in the distribution system.
Frequent monitoring of water quality parameters.
Regular disinfection of the water distribution system.
Presence of organic matter in the water supply.
Answer: D
Explanation: The presence of organic matter in the water supply can contribute to the development of biofilm in a dialysis water distribution system. Biofilm formation occurs when microorganisms attach to surfaces and form a protective layer. Organic matter provides a nutrient source for microorganisms, supporting their growth and biofilm formation.
