“…These bacteria have a low growth rate, strong affinity with nitrite and ammonium, are found in wastewater and also in natural systems, such as mangroves, the ocean, estuarine sediments and freshwater lakes. However, due to their low rate of duplication, a large amount of inoculum is needed to carry out aquaculture wastewater treatment (Chávez-Crooker and Obreque-Contreras, 2010; Ni et al, 2020;Scheeren et al, 2011).…”

“…The ideal pH range for the development of bacteria is between 6.5 and 8.5, while in very acidic or very basic pH ranges, they can favor the increase in the concentration of ammonia and nitrous acid, which inhibits the development of Anammox bacteria. Ni et al (2020) report that the anammox process is favored in wastewater that has a low carbon/nitrogen (C/N) ratio; that is, with a high concentration of ammonium and a low concentration of organic matter, thus reducing operating costs with the addition of an external carbon source, used for the growth of heterotrophic bacteria in the conventional biological denitrification method.…”

“…16 n. 6, e2747 -Taubaté 2021 aquaculture production. The poor quality of the water in the tanks, caused mainly by the accumulation of nutrients, make these environments conducive to the proliferation of pathogens, contributing to weight loss, malformation, intoxication, stress and death of the cultivated animals (Hlordzi et al, 2020;Ni et al, 2020;Song et al, 2011;Zoppas et al, 2016). In addition to environmental and productive problems, wastewater may contain other contaminants, such as heavy metals, hormones or antibiotics, which can also cause problems to human health (Chatla et al, 2020;Turcios and Papenbrock, 2014).…”

Aquaculture plays an important role in providing protein-rich foods, meeting the growing demand for fish. However, aquaculture is a potentially polluting activity, especially with regard to water pollution, due to the improper disposal of wastewater from the production process. Aquaculture wastewater is rich in nutrients (ammonia, nitrate, nitrite and phosphorus) and organic matter, and is commonly discharged into the environment without proper treatment. This can cause a series of environmental impacts and aggravate the current water crisis. Due to the importance and need to reduce environmental impacts, plan the use of water resources and achieve an efficient and sustainable production process, many researchers have focused their studies on effluent treatment techniques designed to remove these nutrients. This article therefore presents an updated review of the main physicochemical and biological techniques used in the removal of nutrients, which can mitigate environmental problems arising from aquaculture activities and contribute to the sustainability of the activity. Keywords: biological removal, nitrogen compounds, sustainable activity.
