Designation:D728506(Reapproved 2010)Standard Guide forRecordkeeping Microfiltration and Ultrafiltration Systems1This standard is issued under the fixed designation D7285;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 record-keeping of microfiltration(MF)and ultrafiltration(UF)sys-tems.1.2 This guide includes a start-up report,recordkeeping ofMF/UF operating data,recordkeeping of pretreatment operat-ing data,and a maintenance log.1.3 This guide is applicable to waters including surfacewater,ground water and some wastewater(secondary effluent)but is not applicable to membrane bioreactors or processstreams.1.4 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 WaterD4195 Guide for Water Analysis for Reverse Osmosis andNanofiltration ApplicationD5090 Practice for Standardizing Ultrafiltration PermeateFlow Performance DataD6161 Terminology Used for Microfiltration,Ultrafiltration,Nanofiltration and Reverse Osmosis Membrane ProcessesD6698 Test Method for On-Line Measurement of TurbidityBelow 5 NTU in WaterD6908 Practice for Integrity Testing of Water FiltrationMembrane Systems3.Terminology3.1 DefinitionsFor definitions of terms used in this guide,refer to Terminologies D1129 and D6161.3.2 Definitions of Terms Specific to This StandardFordescription of terms relating to MF/UF,refer to PracticeD5090.4.Significance and Use4.1 Proper operation and maintenance of an MF or UFsystem are key factors in obtaining successful performance.This guide provides the necessary input for the evaluation ofthe performance of the MF/UF system,the pretreatmentsystem,and the mechanical equipment in the plant.4.2 This guide is for general guidance only and must not beused in place of the operating manual for a particular plant.4.3 Site-dependent factors prevent specific recommenda-tions for all recordkeeping.Thus,only the more generalrecordkeeping is covered by this guide.4.4 This guide can be used for both surface and groundwater and systems which contain either spiral-wound orhollow-fiber devices.5.Procedure5.1 Start-Up Report:5.1.1 Provide a complete description of the plant.This canbe done by using a flow diagram and equipment,instrumenta-tion,and material lists to show water source,pretreatmentsystem,configuration,and posttreatment system.5.1.2 Record initial performance of pretreatment systems asprovided in 5.2 and 5.3,respectively.5.1.3 Calibrate all gauges and meters based on manufactur-ers recommendations.5.2 MF/UF Operating Data:5.2.1 Record the permeate and reject volume or flow ratefrom the system.5.2.2 Record the feed,permeate,and transmembrane pres-sures of each skid as applicable.5.2.3 Record the water temperature of the feed or permeatestream.5.2.4 Record the pH of the feed or permeate stream.5.2.5 Record the turbidity of the feed,and permeate,streams.When possible,permeate turbidity should be recorded1This 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 May 1,2010.Published May 2010.Originallyapproved in 2006.Last previous edition approved in 2006 as D7285 06.DOI:10.1520/D7285-06R10.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 for each skid.For turbidity measurement use Test MethodD6698(nephelometric turbidity).5.2.6 Record the hours of operation whenever data arecollected.5.2.7 Calibrate all gauges and meters based on manufactur-ers recommendation as to method and frequency,but no lessfrequent than once every three months.5.2.8 Record any unusual incidents,for example,upsets inturbidity,pH and pressure,and shut-downs.5.2.9 Complete water analyses of the feed and permeatestreams and the raw water as appropriate to the applicationshall be obtained at start-up and every three months thereafter.NOTE1For all analyses,use ASTM test methods referenced in GuideD4195.5.2.10 The recommended frequency of data collection isgiven in Table 1.5.3 Pretreatment Operating Data:5.3.1 Record the operating
