Description:

Chloride ions are one of the major inorganic anions in water and wastewater.

Although high concentrations of chloride in water are not known to be toxic to

human, its regulation is mainly due to adverse effects on taste. It is essential to

monitor chloride concentrations in boiler systems to prevent metal parts from

being damaged. In high levels, chloride can corrode stainless steel.

The level of chloride concentrations in boiler and cooling towers varies from small

quantities to very high levels. Furthermore high levels of chloride can be toxic to

plant life.

Drinking water: Chloride is a common non-toxic material present in small amounts

in drinking water and produces a detectable salty taste at the aesthetic objective

level of 250 mg/L (limit referred to the EPA Maximum Contaminant Level [MCL]).

Measured levels are normally under 20 mg/L (ppm).
