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.

“…Durante os anos seguintes, o processo Anammox evoluiu de uma parte bastante inexplorada do ciclo biológico do nitrogênio, tornando-se uma peça chave no ciclo global do mesmo. Atualmente, é vista como uma tecnologia revolucionária para o tratamento de águas residuais (Scheeren et al, 2011).…”

“…Under these conditions, ammonium reacts with nitrite, generating molecular N (N 2 ) as the product (Saeed et al, 2012;Scheeren et al, 2011). This process plays an important role in constructed wetland systems where NH 4 + and NO 2 -coexist, thus stimulating the increment in N removal rates.…”

The confined dairy cattle system employs the most modern production techniques with respect to the genetic standards of the herds. The success found in these systems promoted an increase in the number of confined animals and, consequently, an increase in the produced volume of waste, causing the waste from dairy cattle farming to be one of the largest problems in intensive management systems. This effluent has high amount of phosphorus and nitrogen, and the accumulation of these nutrients in surface waters can cause eutrophication of water courses deteriorating their quality. This study is aimed to evaluate the efficiency of a constructed wetland system, cultivated with vetiver grass (Vetiveria zizanioides) in the removal of important environmental pollutants nitrogen (N) and phosphorus (P) from dairy cattle farming wastewater. The effluent received pre-treatment and before passing through the constructed wetland system which was built in a trapezoidal shape. The wastewater from dairy cattle farming, at the inlet and outlet of the constructed wetland system, was biweekly analyzed for different forms of N (ammonia, total Kjeldahl N, nitrate and nitrite) and P. The constructed wetland system proposed cultivated with vetiver grass showed good removal pollutants with greater mean efficiency in the removal of nitrite (43.6%), the total Kjeldahl nitrogen (32.0%) and ammonia (31.0%). Vetiver grass cultivation showed good adaptation to the constructed wetland system, with satisfactory development and no visual symptoms of nutrients deficiency.
