“…The performance of the MBG aeration, the DO in the test water, needs to be eliminated until its concentration reaches 0.0 mg L -1 . Therefore, 20 mg L -1 of sodium sulfite (Na2SO3) were used for the water deaeration through oxidation, together with 0.5 mg L -1 of cobalt chloride (CoCl2) as catalyst (Adel et al, 2019). After that, the water was stirred until the DO concentration reached 0.0 mg L -1.…”

Various types of microbubble generators for use in aquaculture facilities for aeration. The aeration system is essential for high-density shrimp cultivation. However, there is a blockage in the microbubble generator aeration system, and generally, aeration at high densities requires considerable electrical power. In this study, modifications were made to various diameter nozzles and various pump power for microbubble generators. This research was conducted to determine the best microbubble by comparing the nozzle diameter and pump power. To achieve this goal, three diameter nozzles are combined with three different powers with an airflow rate of 2.5 LPM. The best combination of 32.5 mm nozzle diameter and 160-watt pump power. Produce bubbles ranging from 5.6 -82 µm, with an increased oxygen concentration time of 60 minutes.

“…In the study of Claudeet al, (1998) they verified that cascade aerators can be used to oxidize iron and to partially reduce dissolved gases. Adel et al, (2019) studied on speed of impeller and Dissolve Oxygen, They found that rotating speed has a remarkable effect on DO, as the rotational speed increases the time required to reach saturation decreases and consequently the oxygen mass transfer coefficient increases moreover they verified that as the aerator speed increases the standard aeration efficiency (SAE) increases, despite the increase in consumed power. According to Xing et al, (2021) the increase in rotational speed of the impeller will increase the negative pressure at the center, the lifting force of the impeller on the water will increase, and the flow of water thrown by the blade to form a water jump will increase.…”

In any aquaculture plant maintaining dissolve oxygen (DO) level is essential for the better health and survival of the living organisms present in the water body specially fish. DO level can be maintained by aeration process. The general idea behind aeration is to bring the water into intimate contact with the air. Either the water may be discharged into free air or the air may be forced into water. Aeration process also removes light volatile organic compounds, dissolve gases and fix odor, taste etc. in case of drinking water. Some common Apparatus used includes: low cascades, multiple jet fountains throwing water to considerable heights, spray nozzles discharging above the surface of a reservoir, superimposed trays or shelves, submerged perforated pipes, and porous tubes and plates.There are two ways, standard oxygen transfer rate (SOTR) and standard aeration efficiency (SAE) of describing aerator performance. In selection of aerators for aeration in fish culture tank, durability and good standard aeration efficiency (SAE) value is too important moreover in case of aerators high standard oxygen transfer rate (SOTR) is important for the better growth of aquatic animals present in water. This article gives a review of different types of aerators used in aeration process based on various basis.

“…The drawbacks and effects of turbulence and pressure drop on the existing vapour separator design have studied to improve the efficiency levels. Adel et al [12] have discussed that the standard aeration efficiency has increased concerning to the impeller's rotational speed. The maximum standard aeration efficiency (SAE) achieved if the number of impeller blades increased and reduced due to the quick increase of input power.…”

The flow nozzle aerator, which is the part of the water tap made up of Acrylonitrile Butadiene Styrene (ABS), can be modified entirely with a new design. The curved and cone-shaped slopes are used to improve the smooth flow at uniform velocity. Simultaneously, discharge is optimum by modified interior design. The smooth laminar delivery of water with optimum pressure, the liquid element at the aerator end becomes smooth. The assembled nozzle aerator solid model has been generated before experimentation. This can promote through the prediction by the modern tool ANSIFLUENT and Computational Fluid Dynamics (CFD) for finding the flow behavior and its outlet characters. The solid model can be fabricated to prototype for accurate dimensions by using 3D printing technology. Comparing fluid motion with the time consumption of filling water has been done over these different kinds of aerator and nozzle models, which are fabricated by 3-dimensional printing.
