Indeed, in the final analysis, this is the primary reason for being concerned with plant variations. Dissolved oxygen variations of 1.0 mg/l or greater appear to be possible from a mathematical model of the stream and the observed treatment plant spectrum. The theory indicates that the maximum DO variability will occur at the location of the critical DO deficit.3070082 bytesapplication/pdfen-USTime Series AnalysisWater QualityVariance Spectra AnalysisFourier AnalysisTechnical Report
