Is Chlorine Dioxide expensive?
The cost of chlorine dioxide is dependent on the cost of the precursor chemicals-sodium chlorite or sodium chlorate-and the chemicals required to convert these chemicals into ClO2. The cost of ClO2 will also depend on the generation method employed. When compared to the cost of chlorine, the cost of ClO2 is higher. However in those instances in which chlorine is not the preferred regulatory or environmental alternative, ClO2 is a very attractive alternative. The capital equipment costs of generating ClO2 are also far less than that of other alternatives like ozone which can also be used for water treatment.
