“…Venturi bubble generator attracts increasingly attention in recent years and shows potential in many applications. Being as an aeration device, it can increase the concentration of dissolved oxygen in the water to promote the growth of fish and plants, and has been successfully applied to fish farming (Akhtar et al, 2018) and agriculture production (Bagatur, 2014;Dahrazma et al, 2019). With the ability of supplying a large number of fine bubbles, Venturi bubble generator has a good prospect in waste water treatment (Mitra et al, 2016;Kaya et al, 2017), mineral flotation (Ahmadi et al, 2014;Reis and Barrozo, 2016), ship drag reduction (Kawamura et al, 2004;Hashim et al, 2015), and bioreactors (Krusong et al, 2015;Kayaalp and Ozturkmen, 2016).…”

Venturi-type bubble generators own advantages of simplicity in structure, high efficiency, low power consumption, and high reliability, exhibiting a broad application potential in various fields. This work presents a literature review of recent progress in the research concerning Venturi-type bubble generators, with a focus on the performance evaluation, bubble transportation, and breakup mechanisms. Experimental studies employing flow visualization techniques have played an important role in exploring the bubble transportation and breakup phenomena, which is vitally necessary for clarifying the bubble breakup mechanisms and understanding the working principle and performance of a Venturi channel as a bubble generator. A summarization was carried out on both experimental and theoretical work concerning parameters influencing the bubble breakup and the performance of Venturi-type bubble generators. Based on the geometric parameter optimization combined with appropriate flow conditions, it is expected that Venturi-type bubble generators can produce bubbles with controllable size and concentration to satisfy the application requirements, while a further work is required to illustrate the interaction between the liquid and gas bubbles.

“…Golden mahseer, Tor putitora (Hamilton, 1822) is an internationally sought-after sport fish and is being promoted as the flagship species of the Indian subcontinent [1] , [2] , [3] . Besides food values, golden mahseer has great aquaculture perspectives for eco-tourism and provides economic opportunities to native communities [ 4 , 5 ].…”

“…Large-scale seed production using captive broodstock of T. putitora and subsequent stock enhancement through release of hatchery produced healthy fingerlings/juveniles has been suggested as an effective strategy for its conservation and rehabilitation in their natural environment [ 4 , 8 ]. In this line, consistent efforts have been made to achieve artificial propagation and mass scale seed production in captivity [1] . Nevertheless, the success of stock enhancement/ranching programs strongly depend upon the quality and overall fitness of the seed/juvenile released [9] .…”

“…By using a venturi tube as an aeration device, it is possible to increase the concentration of dissolved oxygen in the water to promote the growth of aquatic life and plants. Venturi aeration systems have recently been applied to fish farming [12] and to agriculture production [13,14]. Since venturi aerators are able to produce large number of fine bubbles, they can have a significant impact in waste water treatment plants as well [15,16].…”

In wastewater treatment plants, aeration plays a significant role as it encourages aerobic respiration of microbes, which are necessary to break down carbonaceous matter in the waste stream. This process can account for the majority of energy use in wastewater treatment plants. The aeration process is also necessary in odor control in lagoons and in the aquaculture industry. Generally, the aeration process is accomplished with compressors or blowers which can be of low efficiency due to ideal gas laws. This study introduces the idea of increasing aeration efficiency by looping water from a reservoir through a piping network which includes a venturi aspirator at its inlet. For this purpose, an experimental study has been conducted in a laboratory setup with a pump which pulls water from a tank, passes it through a Venturi aspirator and a helical piping network intended to increase bubble residence time, before depositing it back into the bulk fluid tank. This same process is modeled computationally, using a discrete bubble method (DBM), with good agreement with experiments. The overall purpose here is to determine the optimal configurations for standard aeration efficiency (SAE) and the standard oxygen transfer rate (SOTR). A parametric study has been implemented using the DBM based on different hydraulic and flow parameters. The model is also used to predict the SAE of a hypothetical aeration system. Results indicate that it is possible to achieve SAE values in the range of surface aerators or submersed jet aerators using the proposed aeration system with less complex components, thereby decreasing overall costs.
