Abstract:

© 2019 Elsevier Ltd Hysteresis effect on backwashing in a submerged MBR was investigated with dead-end hollow fiber membranes. The out-of-step changes in TMP and flux is the real hysteresis effect which is common but easily overlooked. Methods of visualization and ultrasonic spectrum analysis were implemented. The results showed that fouling layer is just the culprit of hysteresis effect. Fouling level and fiber length were determined as two key factors that affect hysteresis effect by data and model derivation. Moreover, a hysteresis evaluation index “τbw” is proposed to quantify the result of TMP vs time. The relationship between influence factors and “τbw” is interactive. A linear relationship between fouling level and “τbw” was found as well as an extreme value between fiber length and “τbw”. A lower fouling level (lower backwashing flow) and optimal backwashing duration will be helpful for an effective backwashing no matter for membrane fouling control or energy cost reduce.
