Sentence examples for bubble diffuser from inspiring English sources
A comparison of TOC removal percentage between bubble column reactor and bubble diffuser using ozonation were reported.
The MBR was provided with a Speece cone concentrated oxygen delivery system to overcome the oxygen transfer limitations of conventional bubble diffuser aeration systems at high MLSS concentrations.
In the bubble column, equipped with a fine bubble diffuser, the overall gas hold-up (ϵG) and volumetric oxygen transfer coefficients (kLa) were measured.
The biomass concentration is mainly limited by the extremely low oxygen transfer efficiency (OTE) experienced by conventional aeration bubble diffuser systems at mixed liquor total suspended solids (MLSS) concentrations higher than 20 g L−1.

The kinetic modeling approach, using PHREEQC, accurately simulates observed variations in pH, Fe(II) oxidation, alkalinity consumption, and associated dissolved gas concentrations during transport downstream of the CMD outfalls (natural attenuation) and during 6-h batch aeration tests on the CMD using bubble diffusers (enhanced attenuation).
In order to optimize aeration in the activated sludge processes, an experimentally validated numerical tool, based on computational fluid dynamics and able to predict flow and oxygen transfer characteristics in aeration tanks equipped with fine bubble diffusers and axial slow speed mixers, is proposed.
The reactor was supplied with oxygen by fine bubble air diffuser.
The air was introduced into the each reactor with a bubble air diffuser at the bottom of the each reactor, and the air flow rate was controlled with an air flow-meter connected to blower (aeration rate, 4 l/min).
PBR was filled with culture medium, and oxygen was bubbled through a diffuser at the bottom of PBR.
It was found that specific surface area of bubbles, aeration intensity, and diffuser submerged depth had positive effect on the oxygen transfer coefficient (kLa), while some mixed liquor characteristics such as the mixed liquor suspended solids (MLSS) concentration and apparent viscosity exerted negative function on it.
