“…There are various types of MBGs have been developed, such as; dissolved air flotation (DAF) [8,9], Nozzle venturi [10], Orifice [1,6,11], Venturi [12][13][14][15][16], Injector [17,18] and direct air [8,19]. However, existing MBG systems provide less than maximum results, such as blockage [20] and ineffective [21]. There are some MBG that has been in the application on aquaculture but have not been measured bubbles.…”

Investigates Microbubble characterization is an essential component of any experimental investigation of new microbubble generator design. The use of microbubble generators as aeration systems often experiences blockages. That is caused by the broad cross-section of nozzles and air holes with small diameters. The microbubble generator was redesigned by increasing the cross-sectional area and diameter of the air hole. The method of investigating the bubble process uses image capture with three aperture speeds of the lens of 1/125f, 1/160f, and 1/200f with a combined airflow rate of 0.5 Lpm, 1.5 Lpm, and 2.5 Lpm. The result was characterized with multiple lens apertures with 1/160f bubble results ranging from 5.4 - 94.3 μm at all airflow rates.
