1、Designation: D 5131 90 (Reapproved 2001)Standard Guide forRecord Keeping for Electrodialysis/Electrodialysis ReversalSystems1This standard is issued under the fixed designation D 5131; 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 (e) 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 electrodialysi
3、s 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 acomplet
4、e 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.

7、ntenance 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 gu
8、ide 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. T
9、hus, 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
10、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 for pres-sures, flows, water analysis for raw water and ED/EDR feedproduct and brine waste, temperature, and dc power
11、applied tothe 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:NOTE 1ED/EDR
12、 process monitoring equipment and site specificmonitoring equipment vary with manufacturers designs. Consult theequipment manufacturer to determine the specific listed items to bemonitored.NOTE 2The periodic polarity reversal in reversing electrodialysissystems upsets the process equilibrium. Data s
13、hould 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 coll
14、ection, such as once per shift,for daily items, may be justified.1This 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 Oct. 26, 1990.
