ISO 23043-2021 工业废水处理回用工艺评价方法 Evaluation methods for industrial wastewater treatment reuse processes

This document specifies the principles and framework for comprehensive evaluation of industrial 
wastewater treatment reuse processes, including:
a) establishing goals and scope;
b) illustrating the evaluation procedure; and
c) determination of evaluation indicators (technology indicator/sub-indicators, environment 
indicator/sub-indicators, resource indicator/sub-indicators, economy indicator/sub-indicators).
This document describes how to comprehensively evaluate industrial wastewater treatment reuse 
processes using the proposed calculation approaches and recommended indicators. It does not specify 
methodologies for single evaluation indicators.
The document is intended to provide assistance to a broad range of industrial wastewater treatment and 
reuse project stakeholders including professionals (planning, management, designers, and operators), 
administrative agencies (monitoring, assessment, regulation and administration) and local authorities.
This document is applicable to
a) evaluating comparing and selecting industrial wastewater treatment reuse processes,
b) implementing continuous improvements,
c) upgrading processes and improving performance for existing treatment and reuse facilities.
The intended application of the comprehensive evaluation result is considered within the goal and 
scope definition.
