Designation:D513190(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,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 reversal(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 delineation 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 applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D1125 Test Methods for Electrical Conductivity and Resis-tivity of WaterD1129 Terminology Relating to WaterD1253 Test Method for Residual Chlorine in WaterD1889 Test Method for Turbidity of Water(Withdrawn2007)3D4189 Test Method for Silt Density Index(SDI)of WaterD5091 Guide for Water Analysis for Electrodialysis/Electrodialysis Reversal Applications3.Terminology3.1 DefinitionsFor definitions of terms used in this guiderefer to Terminology D1129.4.Significance and Use4.1 Proper operation and maintenance 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 guide 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.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 andequipment material and instrumentation lists.5.1.2 Provide a listing of all specific chemicals used withtheir design dosage rates.5.1.3 Provide a listing of all design parameters forpressures,flows,water analysis for raw water and ED/EDRfeed product and brine waste,temperature,and dc powerapplied to the ED/EDR system.5.1.4 Provide a record of instrument calibrations in accor-dance with manufacturers recommendations.5.1.5 Record initial performance of the pretreatment,ED/EDR,and post treatment systems as provided in 5.1,5.3,and5.4 respectively.5.2 ED/EDR Operating Data:NOTE1ED/EDR process monitoring equipment and site specificmonitoring equipment vary with manufacturers designs.Consult the1This guide is under the jurisdiction of ASTM Committee D19 on Water and isthe direct responsibility of Subcommittee D19.08 on Membranes and Ion ExchangeMaterials.Current edition approved June 1,2014.Published July 2014.Originally approvedin 1990.Last previous edition approved in 2007 as D5131 90(2007).DOI:10.1520/D5131-90R14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 equipment manufacturer to determine the specific listed items to bemonitored.NOTE2The periodic polarity reversal in reversing electrodialysissystems upsets the process equilibrium.Data should not be taken duringthe period of reversal.Consult the equipment manufacturer to determinethe periods of time at which operating data should be taken.5.2.1 The recommended minimum frequency of data collec-tion is daily unless otherwise noted.On large or criticalsystems more frequent data collection,such as once per shift,for daily items,may be justified.5.2.2 Record applicable pressures,including5.2.2.1 Feed pump discharge pressure,5.2.2.2 Cartridge filter inlet pressure,5.2.2.3 Cartridge filter outlet pressure,5.2.2.4 Brine pump discharge pressure,5.2.2.5 Feed pressure to stack(s),5.2.2.6 Brine pressure to stack(s),5.2.2.7 Product pressure from stack(s),5.2.2.8 Brine pressure
