What type of water is subject to pH testing by engineering department personnel?

The correct choice pertains to the testing of feed water. Feed water is the water supplied to a boiler or steam generator to produce steam or hot water. Ensuring that feed water is within the appropriate pH range is crucial because improper pH levels can lead to corrosion or scaling within the boiler system. If the water is too acidic or too alkaline, it can damage equipment and reduce efficiency, making its pH testing vital for maintaining the operational integrity of the system.

This focus on feed water emphasizes not only the importance of water quality in industrial processes but also the significance of routine monitoring and maintenance in preventing costly repairs and ensuring safe operations. Proper management of feed water quality helps in maintaining optimal performance and extending the lifespan of equipment used within the engineering department.
