Performance evaluation of treatment technologies for water reuse systems Part 9: Guidelines and requirements for electro-chlorination Published (Edition 1, 2025)

Abstract

This document provides guidelines and requirements to evaluate the performance of the method to produce sodium hypochlorite (NaOCl) by electro-chlorination (EC), and to evaluate its disinfection performance for water reuse treatment. It provides a system for evaluating water quality to verify the performance of EC through general parameters, such as the concentration of residual chlorines obtained by electrolysis.
