1、Designation: D5131 90 (Reapproved 2014)Standard Guide forRecord Keeping for Electrodialysis/Electrodialysis ReversalSystems1This standard is issued under the fixed designation D5131; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,

2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers procedures for well defined recordkeeping for electrodialysis (ED) and electrodialysis r

3、eversal(EDR) systems.1.2 This guide includes a start up report and record keepingfor ED/EDR and pretreatment operating and maintenance data.1.3 This guide is applicable to all waters but is not neces-sarily complete for waste waters.1.4 This is a guide only and should not be construed as acomplete d

4、elineation of all record keeping required for aspecific application.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the a

7、intenance of an ED/EDR sys-tem and any associated pretreatment system are key factors inobtaining optimum performance. This guide provides thenecessary input data for the evaluation of the performance ofthe ED/EDR system, the pretreatment system, and the me-chanical equipment in the plant.4.2 This g

8、uide is for general guidance only and must not beused in place of the operating manuals and manufacturersrecommendations for specific equipment or a specific applica-tion.4.3 Site dependent, equipment design and regulatory re-quirement factors prevent specific recommendations for allrecord keeping.

9、Thus, only general record keeping relating tooperation and maintenance is covered by this guide.5. Procedure5.1 Start Up Report:5.1.1 Provide a complete description of the water source,pretreatment system, ED/EDR plant, and post treatment equip-ment. This can be done by using the system flow diagram
