“…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.

Domestic and industrial wastewaters are characterized by high organic content along with other diverse pollutants. Modern wastewater management comprises efficient removal of pollutants and gain energy to fulfil the discharge standards, protect the environment and sustain economic development. Until the last few decades, aerobic treatment technologies were dominant in wastewater treatment. Despite efficient treatment, large energy consumption for aeration, high operational cost and production of a great amount of sludge are the main drawbacks of aerobic systems. Wastewater treatment by anaerobic biological processes has many advantages over aerobic and other removal systems [1]. In addition to higher organic matter removal with less nutrient requirement, lower sludge production and energy-rich methane (CH 4) production are the main outcomes of anaerobic technologies. Various individual and combined anaerobic reactor systems have been successfully applied for the treatment of wastewater [2-5]. Anaerobic bioreactors contain a diverse microbial community, and slow-growing methanogens are very sensitive to changes in environmental conditions. In order to achieve the high treatment performance

“…It was suggested that the process was eco-friendly and a cost-efficient method for remediating pharmaceutical wastewater. Kaya et al (2017) utilized a hybrid ozonationanaerobic membrane bioreactor (AnMBR) system to treat etodolac chemical synthesis wastewater from the pharmaceutical industry. It was observed that up to 99% etodolac removal efficiencies were achieved.…”
