Over the recent decades, the escalating expenses associated with energy provision
alongside the implementation of rigorous ecological regulations have engendered a …

Providing aeration is the primary purpose of a flotation machine. Novel flotation machines
have directly driven significant developments in the aeration system. This paper provides a …

Venturi-type injectors have been used usually due to the practical use and modular design
that allows for quick configuration, ready-to-use, and low-cost solutions in the last years. This …

This experimental study investigated how changes in the water flow rate affected the number
and size of microbubbles using venturi with equal entry and exit angles of 30°. The water …

A novel magnet-driven rotary mixing aerator (MDRMA) was proposed to reduce the diameter
and rising rate of bubbles while improving CO 2 mass transfer during microalgae growth in a …

Bisphenols are important industrial materials for example for the production of plastics, but
are also well known for their adverse health effects, in particular bisphenol A (BPA) is an …

Mass transfer coefficient k L a determines the flux of dissolved oxygen DO in bubble
columns. The k L a values can be determined experimentally or predicted using a …

Modulation of bubble behavior and flow field structure is an effective way to enhance mass
transfer. In this study, a novel porous Venturi structure is proposed, and the bubble …

In this paper, we designed a new venturi bubble generator, which mainly consist of two
serial rectangular perspex venturi channels with the same geometrical dimension …

Dissolved oxygen is one of the leading indicators of aquatic quality. This study explored a
membrane-based bubble generator (MBG) for oxygen dissolution in water. It is achieved by …
