Which condition caused by improper water treatment may be corrected by maintaining proper alkalinity?

Maintaining proper alkalinity in boiler water is crucial for preventing foaming and carryover. When the alkalinity levels are not adequately controlled, it can lead to excessive levels of dissolved solids and other contaminants, which may increase the risk of foaming. Foaming occurs when steam bubbles form in the boiler water, capturing water and causing it to carry over into the steam system. This carryover can lead to issues such as reduced efficiency, contamination of steam, and damage to equipment.

Proper alkalinity helps to stabilize the pH of the boiler water, reducing the likelihood of conditions that lead to foaming. It ensures that the right balance of chemicals is maintained, supporting the overall health of the boiler system. In contrast, scaling, corrosion, and clogging are generally influenced by other factors such as temperature, pressure, and the presence of specific contaminants or metals, rather than solely by alkalinity levels. Therefore, maintaining proper alkalinity is particularly effective in combating foaming and carryover in boiler operations.
