What is the key difference between feed water and potable water?

The key difference between feed water and potable water lies in their intended uses and treatment processes. Feed water is specifically treated to meet the purity requirements necessary for steam generation in a boiler or reactor. This treatment typically involves removing impurities, such as minerals and organic matter, to prevent corrosion and scaling within the system.

On the other hand, potable water is meant for human consumption and must meet stringent safety and health standards to ensure it is safe for drinking and cooking. While both types of water may undergo certain treatment processes, feed water focuses on the requirements of the steam systems, while potable water prioritizes human health.

Therefore, the designation of feed water as being treated for purity is correct since it reflects the specific treatment aimed at maintaining the efficiency and safety of steam-producing operations. The distinction between these water types is crucial for their respective applications in ensuring operational safety and health standards.
