Effects of micro-bubble aeration on the pollutant removal and energy-efficient process in a floc-granule sludge coexistence system

To investigate energy-saving approaches in wastewater treatment plants and decrease aeration energy consumption, this study successfully established a floc-granule coexistence system in a sequencing batch airlift reactor (SBAR) employing micro-bubble aeration. The analysis focused on granule formation and pollutant removal under various...

Ultrafast ultrasound for super­resolution imaging: The effect of pulse inversion and harmonic­ or SVD­filtering on microbubble detection

Background/purpose: The mapping of microvasculature requires a high­resolution imaging method. Super­resolution ultrasound­imaging can provide such high resolution by detecting individual microbub­ bles (MBs) in a flow circuit. This method relies on the dynamic appearance of MBs, which appear as point scatterers on the US image, mixed with...

Effect of aeration by micro - bubbles on methane production in anaerobic digestion

This study aims to look at the effect of introducing controlled amounts of oxygen on biogas quantity and quality during anaerobic digestion. The anaerobic digestion process is studied, specifically, it’s biochemical processes, to understand the effect of addition of oxygen. Anaerobic sludge is aerated to mimic DAF (Dissolved Air Flotation)...
