What parameter is NOT typically evaluated during direct monitoring in water treatment?

In water treatment, direct monitoring typically involves evaluating parameters that can quickly indicate the state of water quality and treatment effectiveness. Turbidity, hardness, and pH are commonly measured because they provide immediate insights into the clarity, mineral content, and acidity or alkalinity of the water, respectively.

Turbidity measures the cloudiness of water caused by particles suspended in it, which can indicate the presence of contaminants or the effectiveness of filtration processes. Hardness assesses the concentration of minerals like calcium and magnesium, important for understanding scaling and corrosion potential. pH indicates the acidity or alkalinity of the water, which can affect chemical reactions during treatment and the efficacy of disinfection processes.

Electrical conductivity, on the other hand, measures the ability of water to conduct electrical current, which is related to the concentration of dissolved ions. While it can provide useful information about ionic composition and salinity, it is not as frequently monitored on a direct basis compared to the other parameters. Instead, conductivity is often used more in specific situations or as a supplementary parameter rather than a core part of routine direct monitoring in water treatment processes.
