- Scope
4.1 Proper operation and maintenance of RO and NF systems are key factors in obtaining successful performance. This guide provides the necessary input for the evaluation of the performance of the RO and NF systems, the pretreatment system, and the mechanical equipment in the plant.
4.2 This guide is for general guidance only and must not be used in place of the operating manual for a particular plant.
4.3 Site-dependent factors prevent specific recommendations for all recordkeeping. Thus, only the more general recordkeeping is covered by this guide.
4.4 This guide can be used for both brackish and seawater systems which contain either spiral-wound or hollow-fiber devices.
1.1 This guide covers procedures for well-defined recordkeeping of reverse osmosis (RO) and nanofiltration (NF) systems.
1.2 This guide includes a start-up report, recordkeeping of RO and NF operating data, recordkeeping of pretreatment operating data, and a maintenance log.
1.3 This guide is applicable to waters including brackish waters and seawaters but is not necessarily applicable to wastewaters.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
