Scope

Scope: This document specifies the calculation method for the water reuse rate in textile enterprises, workshops within textile enterprises, and designated water use units. This document is applicable to textile enterprises, workshops within textile enterprises, and the calculation of water reuse rates in designated water use units. Main technical content: 5. Standard content 5.1 Scope of application This standard specifies the calculation method for the water reuse rate in textile enterprises. This standard is applicable to the calculation of water reuse rates in textile enterprises and workshops within textile enterprises. 5.2 Textual framework The main content of this standard includes seven parts, namely: ? Scope ? Normative references ? Terms and definitions ? General requirements ? Reused water volume ? Measurement ? Calculation of water reuse rate ? Appendix 5.3 General requirements In the general requirements, the meaning of water reuse is clarified, and at the same time, it is specified that the water volume in some cases does not belong to the reused water volume. 5.4 Reused water volume The focus is on determining various forms of water reuse and the corresponding water volumes. 1. Circulating water volume: There are single circulating reuse water volume and integrated circulating reuse water volume. 2. Series water volume: There are single series reuse water volume, integrated series reuse water volume, and continuous series circulating reuse water volume. 3. Mixed reuse water volume is a combination of circulating reuse and series reuse. 5.5 Measurement 1. It is required that the measurement instruments comply with the corresponding national standards. 2. The measurement steps of reused water volume are specified. 3. Requirements are put forward for the installation of water meters for various reused water volumes. 5.6 Calculation of water reuse rate 1. The calculation formula for water reuse rate is g
