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

10、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 gu
