- Only correlations significant at the 95% level are shown. + indicate positive correlation and – a negative correlation. Treatment A: PDT 50, No alignment correction, no normalization. Treatment B: PDT 50, Alignment correction using the systematic shift correction procedure, normalization of consensus profiles using the TFN-areas procedure. Treatment C: PDT 100, Alignment correction using the systematic shift correction procedure, normalization of both replicate and consensus profiles using the TFN-heights procedure. In all treatments consensus profiles were generated from two replicate profiles only considering T-RFs present in both. Process parameters: COD - Total COD going into the activated sludge tanks (mg/l), P - Total phosphorus concentration in primary settled wastewater (mg/l), F/M - Food to microorganisms ratio (g/kg*s), I - Inorganic fraction of the activated sludge (%), H - Humic substances in the activated sludge (mg/gMLSS), T - Water temperature, Fe - Total iron dosage, EtOH - Ethanol dosage, PD - Polymer dosage, S - Shear sensitivity of activated sludge flocs, SC - Carbohydrate content in the activated sludge (mg/gMLSS), ESS - Effluent suspended solids (mg/l).
