This document provides guidelines on methods for evaluating the performance of ion exchange and electrodialysis for water reuse including ion exchange resin and ion exchange membrane.

Abstract

Overview

Key Topics

Performance Evaluation Methods: The standard defines how to assess both functional and non-functional requirements of ion exchange and electrodialysis processes in water reuse applications.
System Configurations: It covers the setup of ion exchange resin towers and electrodialysers, including the use of cation and anion exchange materials.
Process Design and Selection: Guidance is provided on selecting the appropriate type, structure, and configuration of resins and membranes for different water types and treatment objectives.
Operational Considerations: Recommendations for operational parameters, maintenance, regeneration cycles, and performance measurement are detailed.
Evaluation Criteria: Parameters such as treated water quality, ion exchange capacity, current efficiency, and water recovery rate are emphasized for comprehensive system evaluation.

Applications

ISO 20468-6:2021 is essential for a wide range of water treatment and water reuse scenarios where effective ion removal or desalination is required.

Typical applications include:

Industrial Water Purification: Softening and demineralizing water for boiler feed, ultra-pure water production, and chemical processing.
Municipal Water Reuse: Enhancing the quality of reclaimed water for potable or non-potable purposes by removing salts, minerals, and other ions.
Wastewater Treatment: Recovery of valuable components and treatment of industrial or landfill leachate to comply with environmental standards.
Food and Beverage Industry: Water softening and desalination to meet strict sanitation and quality standards.
Seawater and Brackish Water Desalination: Producing fresh water for municipal supply or table salt production.

These methods are particularly suitable when water treatment goals require high selectivity, efficient ion removal, and adaptability to diverse raw water sources.

Related Standards

Organizations involved in water treatment and water reuse may benefit from referencing the following related standards:

ISO 20468-1: Guidelines for performance evaluation of treatment technologies for water reuse systems – General principles and framework (basis for all parts of ISO 20468).
ISO 20670: Water reuse – Vocabulary (defines key terms used in ISO 20468-6 and related documents).
Other Parts of ISO 20468: Covering additional types of advanced treatment technologies such as membranes, UV, ozone, and distillation.

By using ISO 20468-6:2021 in conjunction with these related documents, stakeholders can ensure a robust, standardized approach to assessing and improving the performance of water reuse technologies-strengthening efficiency, regulatory compliance, and sustainability in water management operations.
