Which of the following is NOT a benefit of using deionized water for feedwater?

Deionized water is highly beneficial for use in feedwater systems for several reasons, which makes it an ideal choice in many industrial applications. Among its advantages, deionized water significantly reduces the risk of corrosion in boiler systems because it contains very low levels of dissolved salts, which are typically responsible for corrosive reactions. Additionally, it prevents scale buildup on heating surfaces by eliminating minerals that would otherwise precipitate and form deposits. The enhanced purity of steam produced from deionized water is another critical benefit, as it ensures the removal of contaminants that can affect both efficiency and safety in steam systems.

The option stating that it is inexpensive to produce is not a true benefit of using deionized water. In fact, the process of deionization typically involves complex and costly equipment and ongoing maintenance, which can make it relatively expensive to produce compared to other treatments for feedwater. Therefore, recognizing the limitations and costs associated with deionization is essential for making informed choices in the management of feedwater systems.
