Movement Mechanisms Harness Levy Flight for Energy-Efficient Wastewater Treatment in Microalgae-Bacteria Systems.

ABSTRACT: Microalgae-bacteria symbiosis system is significant for sustainable and low-carbon wastewater treatment, with self-aggregation being key to its stable operation and effective pollutant removal. Cellular motility is the main driving force behind self-aggregation, crucial for symbiosis stability, but the characteristics and patterns involved still remain largely unexplored. Here, cellular movement dynamics into the microalgae-activated sludge model (ASM3) is incorporated, enabling synchronized simulation of metabolic activities and movement behaviors through physical and biochemical interactions in bioreactor systems. These findings indicate that microalgae induce bacterial movement towards Lévy flights, thereby increasing the bacterial encounter rate by 12.20%, augmenting signaling molecule
