保持水处理化学品的充足来源，防止化学品增加 为了节约成本，孟菲斯轻气水公司（MLGW）决定寻找一种实用的次氯酸钠替代品。这篇论文 讨论MLGW现场生成次氯酸钠的方法，包括 从批量生产切换到现场生产。现场发电的一些固有优势包括: 漂白强度低，漂白剂降解速度慢，原料易得，来源和交付多 选项。现场发电的一些固有缺点是初始资本成本高、成本增加 操作员技能、大型设备脚印和软水处理要求。最后是环境问题 任何项目都必须考虑问题。这些措施包括电解槽清洁和废物处理 溴酸盐、氯酸盐和氢气的工艺生产。MLGW的结论是，潜在的节约 被巨大的初始成本和水美学的潜在变化所抵消。包括4个参考文献、表格。

To maintain an adequate source of water treatment chemicals and to protect against increasing chemical costs, Memphis Light, Gas and Water (MLGW) decided to search for a practical alternative to bulk sodium hypochlorite. This paper discusses MLGW's approach to on-site-generation of sodium hypochlorite including the pros and cons of switching from bulk manufactured to on-site-generated. Some inherent advantages to on-site-generation are low bleach strength, slow bleach decay rate, highly available raw materials, and multiple sources and delivery options. Some of the intrinsic disadvantages of on-site-generation are large initial capital costs, increased operator skill set, large equipment foot print, and a soft water treatment requirement. Finally, environmental issues have to be considered with any project. These include electrolytic cell cleaning waste disposal and process production of bromates, chlorates, and hydrogen gas. MLGW concluded that the potential savings were outweighed by the large initial costs and the potential change in water aesthetics. Includes 4 references, tables.
