ONSITE GENERATION OF HYPOCHLORITE – IS IT COST EFFECTIVE?
Abstract:On-site sodium hypochlorite generation has been a proven technology since the 1930’s. This process uses salt and electric power to generate chlorine. Salt is dissolved in a brine solution then passed across electrodes powered by a low voltage current. This process produces a dilute hypochlorite of 0.8% in solution. On-site hypochlorite generation requires the construction of a brine tank, rectifier, electrolytic cells, a product tank, metering pumps and controls. Recent improvements in system reliability combined with new regulatory requirements are forcing water and wastewater utilities to reconsider their reliance on chlorine gas. This paper summarizes two economic analyses of disinfection system alternatives that have been recently conducted.
