We present a comprehensive literature review on the two-phase bubble column; in this
review we deeply analyze the flow regimes, the flow regime transitions, the local and global …

This review outlines the current status and recent developments in the technology of
microalgal culturing in enclosed photobioreactors. Light distribution and mixing are the …

A membrane-sparged helical tubular photobioreactor (MSTR) with a cultivation volume of
800ml was designed in this study. It consisted of a cylindrical-shaped light receiver and a …

Biogas desulfurization is in many cases the main purification step required for energy
generation. This is the case of wastewater treatment plants, waste management facilities or …

A humidification-dehumidification (HDH) system using a bubble column humidifier was
optimized using response surface methodology (RSM). The humidifier was integrated with …

The average shear rate (γ˙ av) is a parameter used to characterize the shear environment in
bioreactors, enabling comparison of the performances of different bioreactor models in terms …

Gas sparging performances of a flat sheet and tubular polymeric membranes were
investigated in 3.1 m bubble column bioreactor operated in a semi batch mode. Air–water …

Better understanding of the impact that electrolytes have on the hydrodynamic performance
of airlift reactors, ALR, is critical to improving the design and operational performance of …
