“…Employment of anammox bacteria can revolutionize domestic wastewater treatment because of their ability to simplify removal of nitrogenous waste at significantly lower costs and with less sludge production than that of conventional WWTP nitrification-denitrification processes [34,35] among others [31] consider the anammox process "as one of the most sustainable alternatives to the conventional costly nitrification-denitrification biological nitrogen removal process" in wastewater treatment, particularly for high nitrogen low BOD wastewater streams. The autotrophic anammox process directly oxidizes ammonium to nitrogen gas utilizing nitrite as the electron acceptor without the need for an organic carbon source as required by heterotrophic denitrification processes [36].…”

Water quality in San Francisco Bay has been adversely affected by nitrogen loading from wastewater treatment plants (WWTPs) discharging around the periphery of the Bay. While there is documented use of zeolites and anammox bacteria in removing ammonia and possibly nitrate during wastewater treatment, there is little information available about the combined process. Though relatively large, zeolite beds have a finite ammonium adsorption potential and require periodic re-generation depending on the wastewater nitrogen loading. Use of anammox bacteria reactors for wastewater treatment have shown that ammonium (and to some degree, nitrate) can be successfully removed from the wastewater, but the reactors require careful attention to loading rates and internal redox conditions. Generally, their application has been limited to treatment of high-ammonia strength wastewater at relatively warm temperatures. Moreover, few studies are available describing commercial or full-scale application of these reactors. We briefly review the literature considering use of zeolites or anammox bacteria in wastewater treatment to set the stage for description of an integrated zeolite-anammox process used to remove both ammonium and nitrate without substrate regeneration from mainstream WWTP effluent or anaerobic digester filtrate at ambient temperatures.

“…Este processo remove dois poluentes simultaneamente, amônio e nitrito, convertendo-os a nitrogênio gasoso (Zhang et al, 2008). A razão estequiométrica encontrada para o processo ANAMMOX está na faixa de amônio:nitrito de 1:1,32.…”

“…Quando descartados inapropriadamente em ambientes aquáticos, efluentes com altas concentrações de nitrogênio podem causar efeitos adversos à microbiota aquática e, em contrapartida, alta demanda de oxigênio. Este efeito é caracterizado como eutrofização, resultado do excesso de nutrientes na água, possibilitando a proliferação excessiva de algas e bactérias que levam à consequente diminuição da qualidade do corpo receptor (Zhang et al, 2008).…”

R ESU M OO aumento da escala de produção agropecuária e agroindustrial traz, como consequência, a necessidade por alternativas para a mitigação dos impactos ambientais. As cadeias produtivas de proteína animal (ex.: suinocultura, bovinocultura e avicultura) produzem efluentes com elevada concentração de compostos nitrogenados. Neste contexto, o processo ANAMMOX (do inglês Anaerobic Ammonium Oxidation) se constitui em uma nova estratégia de alto desempenho visando remover compostos nitrogenados de águas residuárias, agropecuárias e agroindustriais, sob condições quimiolitoautotróficas. Este artigo apresenta uma revisão bibliográfica de trabalhos publicados nos últimos 15 anos sobre estudos deste processo, discutindo sua rota metabólica, demonstrando os micro-organismos envolvidos e os parâmetros de controle do processo, além de estudos desenvolvidos no Brasil e possíveis aplicações. Palavras-chave: efluentes, dejetos de animais, tratamento biológicoThe ANAMMOX process as an alternative for treatment of water with high containing nitrogen A B ST R A C T The increase in agriculture and agro-industrial scale production brings the necessity for alternatives to mitigate environmental impacts. The animal protein production chains (e.g. swine, cattle and poultry) produce effluents with high concentration of nitrogen compounds. In this context, the ANAMMOX (Anaerobic Ammonium Oxidation) process is a new strategy for nitrogen removal in a high rate from agricultural and agro-industrial wastewaters under chemolithoautotrophic conditions. This paper presents a literature review of papers published in the last 15 years about the ANAMMOX process, discussing their metabolic pathway, microorganisms, main control parameters as well as studies conducted in Brazil and application possibilities.

“…When improperly discarded in aquatic environments, wastewater with high concentrations of nitrogen and phosphorus can cause eutrophication, resulting from excess of nutrients in the water, allowing the algal blooms that lead to a consequent decrease in quality of the receiving body (ZHANG et al 2008). Even in small concentrations in the environment, copper and zinc can cause toxicity to aquatic biota.…”

This work aimed to study the agronomic performance and capacity of nutrient removal by bermudagrass (Cynodon spp.) and cattail (Typha sp.) when grown in constructed wetlands systems (CWSs) of vertical and horizontal flow, respectively, used in the post-treatment of swine breeding wastewater (ARS). The average yield of dry matter (DM) of bermudagrass in sections of 60-day interval ranged from 14 to 43 t ha -1 , while the cultivated cattail produced in a single cut after 200 days of cultivation between 45 and 67 t ha
