What is one of the main factors that alarms must indicate in water treatment facilities?

In water treatment facilities, alarms are essential for monitoring and ensuring the quality and safety of the water being treated. One of the main factors that alarms must indicate is when a variable is above or below a specified standard. This is crucial because it allows operators to respond promptly to any deviations that could indicate contamination or inefficiencies in the treatment process.

When a parameter such as pH, turbidity, or contaminant concentration falls outside of its normal range, it can pose serious health risks or indicate operational failures. The alarm serves as an immediate alert for personnel to take corrective action, ensuring that the water remains safe for distribution and consumption. Maintaining water quality standards is fundamental to protecting public health and complying with regulatory requirements, making this factor a key focus in alarm systems for water treatment facilities.
