7、intenance 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 g
8、uide 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.
9、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
