摘要: This study presents the tests of an Immersed Membrane BioReactor (IMBR) equipped with a draft tube and focuses on influence hydrodynamic conditions membrane fouling in pilot-scale using hollow fiber module ZW-10 under ambient conditions. In this system, cross-flow velocities across surface were induced by cylindrical draft-tube. The relationship between velocity aeration strength rate (under various conditions) investigated Multi-Dimension Scaling (MDS) analysis. MDS technique is especially suitable for samples many variables has relatively few observations, as data about Bio-Reactor (MBR) often is. Observations are analyzed simultaneously. According to results, specialized form MDS, CoPlot enables presentation results two dimensional space when plotting ratio (output/input) rather than original efficient units can be visualized clearly. indicate that: (i) plays important role IMBR performance; (ii) implementing approach reference consequently useful characterize performance changes classification.
