摘要

On-site electro-chemical generated hypochlorite is a low-cost, strong disinfectantand oxidizing agent with a broad spectrum of applications, and with minimal associatedhazard. This type of generation has been in existence for more than 25 years but only inthe last few years has it emerged as a recognized viable method to replace chlorine gasand high strength hypochlorite. This paper will discuss new manufacturing techniquesthat have proven to reduce raw material consumption and operating costs, with equal orlower capital investment for this two decade old process.Typical operating current density is approximately 0.8 Amps per Square Inch(ASI) or less. It has been determined that increasing the operating current density by50%, will increase the production rate by 50% and have a slight beneficial effect oncurrent efficiency and product concentration. It was also determined that the saltutilization, current efficiency, and product concentrations are all improved by controllingthe electrolyzer operating temperature below the conventional operating parameters. Afurther power consumption and production rate improvement can be realized by feedingall the brine to the inlet of the cell but splitting the water addition between the inlet and atleast one other point along the length of the cell.
