“…In the case of power efficiency in the reactor to which the JVM is applied, it was confirmed that the efficiency was 176 %, 156 %, and 153 % higher compared to the air supply in tap water, MLVSS 3,000, and MLVSS 6,000 mg/L, respectively. In a study of the power efficiency of a total of five aeration devices (venturi jet, scorpion jet, wavesurge, modified paddlewheel, commonly used paddle wheel), the modified paddlewheel showed the highest efficiency at 2.038 kg·O 2 /Kw·hr [ 30 ]. In OTR, VOTR, and OTE, the JVM was evaluated to have about 200 % better oxygen mass transfer characteristics than the air diffuser aerator.…”

“…The oxygen mass transfer characteristics in the aeration tank can be affected by a number of hydrodynamic parameters, including gas flow rate, aeration tank capacity, and bubble size [ 12 ]. Currently, to reduce aeration cost and maximize nitrification efficiency, intermittent aeration, use of simulation software, Enhanced Biological Phosphorus Removal (EBPR) method development, modified paddlewheel, and superoxygenation systems are applied and used [ 13 , 14 , 15 ]. Understanding the factors influencing oxygen transport provides useful information about the applicability of the developed technology, energy efficiency, and nitrification process.…”

“…Aquaculture in ponds has been intensified several times above the natural carrying capacity of a conventional pond by providing intensive aeration (Itano et al, 2019; Jayanthi et al, 2021; Kumar et al, 2013) and removing waste from the system (Nhut et al, 2019). This helps to raise the production, but the cost to the environment remains critical.…”

Since 2000, aquaculture became well‐integrated into the global food system. Aquaculture systems are highly diverse, producing globally equal amounts of fed and extractive species. In Asia and Africa, inland aquaculture provides the bulk of aquaculture production, while in the Americas, Europe, and Oceania, marine aquaculture dominates. The realized growth of annual production since 2000 is due to intensification, the use of more and better feeds, improved production management, and increased attention to biosecurity. Fed and extractive aquaculture, both need to pay more attention to scaling, site selection, and the health of the wider production environment. In terms of land use, aquaculture is more efficient than terrestrial animal production. Still, water use remains a challenge. More attention should be given to water recycling in land‐based systems, reducing water consumption and facilitating nutrient recovery and reuse. Future development should focus on making aquaculture climate neutral and on reducing environmental impacts, both inland and at sea. More attention must be given to making aquaculture an important part of local food systems on all continents, as is the case in Asia today. Integration of aquaculture into local nutrition‐sensitive, circular, and sustainable food systems should become the major driver for future aquaculture system development.

“…Moucanu et al, (2012) found that due to the higher aeration performances and lower energy consumption the use of the fine bubble diffusers is the most adequate solution for the refurbishment of the biological reactor from the Romanian wastewater treatment plants. Jayanthi et al, (2021) studied on three different types of aerators and found that paddlewheel aerators performed better in terms of oxygen transfer and water circulation, than the other three types of aerators viz. Venturi jet, Scorpion jet and Wavesurge.…”

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.
