This document provides guidance and requirements for grade classification of performance of recovered reverse osmosis (RO) membranes for water reuse systems. This standard is applicable to the spiral-wound type of recovered membranes from seawater reverse osmosis (SWRO) and brackish water reverse osmosis (BWRO) systems. This standard is to ensure consistency in the performance of recovered RO membranes. It does not specify any method or process for the recovery of RO membranes.

Overview

ISO 20466:2024 - Guidance for performance grading of recovered reverse osmosis (RO) membranes for water reuse - establishes a consistent framework for classifying the performance of recovered spiral-wound RO membranes from seawater (SWRO) and brackish water (BWRO) systems. The standard defines what information must accompany a recovered RO membrane, how performance grades are presented, and the minimum data required to support safe and predictable reuse in water reuse applications. ISO 20466:2024 does not prescribe recovery or cleaning methods.

Key topics and requirements

Scope and applicability: Applies to spiral-wound recovered RO membranes from SWRO and BWRO systems intended for non-potable water reuse.

Performance grading: Membranes are graded by key performance metrics-salt rejection and flow rate-with classification prefixes to indicate source type (e.g., “S-” for SWRO, “B-” for BWRO). Example grades in the standard include labels such as S-A1 or C1 (introductory examples).

Required information: Each recovered membrane must include, at minimum:

Unique serial number
Grade
Differential pressure
Usage history (raw water type, application, years of operation, membrane area)
Recovered membrane supplier details
Performance test information (test method, conditions and results)

Marking and traceability: Permanent human-readable marking on the element plus optional machine-readable identifiers (2D barcode, RFID). Documents should be attached electronically or in print and protected against counterfeiting (PKI/encoded verification suggested).

Testing and documentation: Performance test methods and conditions are referenced (see Annex A) - suppliers must report test parameters (e.g., feed conditions, temperature, test salt) and measured flow/rejection results.

Limitations: Recovered membranes graded under ISO 20466 are intended for water reuse but not for potable reuse per ISO 20469.

Practical applications

Enables reuse pathways such as cascade reuse (e.g., SWRO membrane repurposed for tertiary wastewater treatment), irrigation, industrial boiler feed water, and other non-potable water reuse uses.

Supports system designers and engineers by providing consistent performance data needed for pump sizing, piping, and process design.

Promotes circular economy goals by extending membrane life, reducing disposal and manufacturing impacts, and supporting SDGs related to responsible consumption and clean water.
