Biofloc production in activated sludge system treating shrimp farming effluent

Abstract: The release of wastewater and the shrimp feed cost are the main challenges faced by the shrimp farming industry. An alternative solution to both problems is biofloc production in a unit external to the farm, in an activated sludge system for effluent treatment. The treatment system’s influent was composed of the shrimp farm wastewater supplemented with urea and sugarcane molasses. The results show that the average removal of chemical oxygen demand was 71% and the average biofloc production in the reactor was a… Show more

“…Los sólidos son partículas de tamaño variable generadas en el ambiente de cultivo y compuestas por heces, bacterias, microorganismos vivos y muertos y alimento no consumido, metabolitos de peces, desprendimiento de perifiton y bioflóculos (Santaella et al, 2018, Bao et al, 2018Paniagua, 2020). En sistemas de recirculación generalmente las principales fuentes de sólidos son el alimento no consumido, las heces y el biofilm (Bao et al, 2018).…”

“…Este, es un tipo de residuo sólido rico en Nitrógeno, Fósforo, carbonos orgánicos, también contiene trazas de metales (Castine et al, 2013). Estos compuestos en altas concentraciones y mal gestionados ocasionan eutrofización, disminución del oxígeno y toxicidad; afectando así la vida en los ecosistemas acuáticos (Santaella et al, 2018Bao et al, 2028Jasmin et al, 2020;Paniagua, 2020).…”

“…The BFT system enables increased productivity with low water renewal [42][43][44][45]. It is composed of flocs, which are formed through the conversion of accumulated organic matter, such as feed waste and feces, and the presence of a community of microbial, heterotrophic bacteria, algae, and protozoa [46]. The bioconversion of biofloc flocs is carried out via a system in continuous water aeration, and the addition of a carbon source like molasses to promote bacterial growth [43].…”

“…Os principais desafios dessa atividade são o custo com a alimentação do camarão e a geração de efluentes ricos em nutrientes e carga orgânica (Ribeiro et al, 2014;Santaella et al, 2018). O tratamento inadequado e lançamento desses efluentes em corpos hídricos podem acarretar impactos ambientais negativos (Sukumaran et al, 2019), como a eutrofização, a perda de serviços ecossistêmicos, entre outros (Ribeiro et al, 2014;Richards & Friess, 2016).…”
