This project is a study on performance of oxygen concentrators over conventional aeration used in aquaculture. Aeration is a method of pumping air to the water to increase the oxygen content. Oxygen rich water is necessary for the healthy growth of fishes. The conventional aeration systems are inefficient in oxygenating the fish tank since it supplies atmospheric air with only 21% oxygen rest is nitrogen and other gases. Thus, the oxygen dissolves less efficiently.
An oxygen concentrator supplies oxygen rich air through its exit. This pure oxygen can be supplied to fish tank for increasing dissolved oxygen levels. An oxygen concentrator filters nitrogen from atmospheric air by using a molecular sieve. The present oxygen concentrators have complex design and function which is not required for fish farming. So, a newly designed oxygen concentrator is introduced in this project.
