Chloride, in the form of chloride (Cl−) ion, is one of the major inorganic anions in water and wastewater. The salty taste produced by chloride concentrations is variable and depends on the chemical composition of water. Some waters containing 250 mg/L Cl− may have a detectable salty taste if the cation is sodium. On the other hand, the typical salty taste may be absent in waters containing as much as 1000 mg/L when the predominant cations are calcium and magnesium...
