Abstract
Recycling of by-product salt from waste treatment procecesses such as incinerator, melting furnance, leachate etc, will be presented to produce eco-NaClO by electrodialysis. This time, newly investigated themes (refreshing method ofelectrodialyser, relationship of liquid concentration vs efficiency, method to reduce deterioration of produced NaClO), and a proposal to use produced eco-NaClO for sewage treatment, will be reported.
