1、Designation: D 7285 06Standard Guide forRecordkeeping Microfiltration and Ultrafiltration Systems1This standard is issued under the fixed designation D 7285; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision
2、. 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 record-keeping of microfiltration (MF) and ultrafiltration (UF) sys-tems.1.2 This gu
3、ide 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
