Investigation on the Performance of Chlorine Dioxide Generators for Drinking Water Disinfection / 环境与健康杂志

ABSTRACT

Objective To preliminarily investigate the conditions of the performance of chlorine dioxide generator for drinking water disinfection and know the overall situation of the industry.Methods From 2007 to 2008,6 companies'products were chosen for this investigation according to certain rules,and their performance indicators,such as chlorine dioxide output and conversion rate were tested by using the Five-step iodimetry method.Results On-site generating technology was commonly used,and the average conversion rate of the compound type generator was 57.06%,and the pure type generator was 84.78%.Conclusion The conversion rate of the pure type generator is better than the compound type,and the newly invented pure type generator has much better performance and lower disinfection cost.
