Advanced monitoring of high-rate anaerobic reactors through quantitative image analysis of granular sludge and multivariate statistical analysis.
Four organic loading disturbances were performed in lab-scale EGSB reactors fed with ethanol. In load disturbance 1 (LD1) and 2 (LD2), the organic loading rate (OLR) was increased between 5 and 18.5 kg COD m(-3) day(-1), through the influent ethanol concentration increase, and the hydraulic retention time decrease from 7.8 to 2.5 h, respectively. Load disturbances 3 (LD3) and 4 (LD4) were appli...
متن کاملPrincipal component analysis and quantitative image analysis to predict effects of toxics in anaerobic granular sludge.
Principal component analysis (PCA) was applied to datasets gathering morphological, physiological and reactor performance information, from three toxic shock loads (SL1 - 1.6 mg(detergent)/L; SL2 - 3.1mg(detergent)/L; SL3 - 40 mg(solvent)/L) applied in an expanded granular sludge bed (EGSB) reactor. The PCA allowed the visualization of the main effects caused by the toxics, by clustering the sa...
متن کاملA chemometric tool to monitor high-rate anaerobic granular sludge reactors during load and toxic disturbances
The wide fluctuations in flow rate and the presence of toxic compounds can damage the high efficiency of high-rate anaerobic granular sludge reactors. As earlier these disturbances are detected, more accurate would be the corrective actions, and less damage will be caused to the microorganisms involved in the process. The use of Principal Component Analysis (PCA) determined a latent variable, c...
متن کاملQuantitative image analysis as a diagnostic tool for monitoring structural changes of anaerobic granular sludge during detergent shock loads.
Two shock loads of a commercial detergent (I-150 mg chemical oxygen demand (COD)/L, fed for 56 h; II-300 mg COD/L fed for 222 h) were applied in a lab-scale Expanded Granular Sludge Blanket (EGSB) reactor, fed with 1,500 mg COD/L of ethanol. The impact of the surfactant was assessed in terms of granular sludge morphology, specific methanogenic activity (SMA) in the presence of individual substr...
