“…1, the maximum TN and COD removals both occurred in logarithmic growth phase when ammonia, nitrite and nitrate were used as the sole sources, which is consistent with other studies (Guo et al, 2013a;Huang et al, 2013;Joo et al, 2005). The COD dropped to 100 mg L À1 after 24 h incubation.…”

“…However, this approach is cost-intensive and time-consuming, because nitrifying bacteria grow slowly and require different conditions (Metcalf and Eddy, 2003). As a new way of nitrogen removal, heterotrophic nitrification-aerobic denitrification phenomenon widely exists in the natural environment and wastewater treatment facilities (Kim et al, 2005;Joo et al, 2005;Robertson and Kuenen, 1990). Compared with traditional ways, it is widely focused for its much higher growth rate and more efficient substrate removal with simultaneous nitrogen removal and organic carbon degradation.…”

“…Freshwater macrophytes (mainly Eicchornia crassipes) are commonly found in the River Cachoeira estuary during the rainy season. Some authors have also reported the ability of bacteria (Thiosphaera pantotropha, Pseudomonas aeruginosa, Pseudomonas stutzeri, Paracoccus denitrificans, Alcaligenes faecalis) to denitrify even in the presence of low levels of dissolved oxygen (BERNAT et al, 2003;CHEN et al, 2003;TAKAYA et al, 2003;JOO et al, 2005).…”

SPATIAL AND TEMPORALVARIATION OF DISSOLVED INORGANIC NUTRIENTS, AND CHLOROPHYLL-α IN a TROPICAL ESTUARY IN NORTHEASTERN BRAZIL: DYNAMICS OF NUTRIENT REMOVAL

Monthly sampling campaigns were carried out between February 2010 and January 2011 to evaluate the spatial and temporal distribution of nutrients (ammonium, nitrite, nitrate, dissolved organic nitrogen, phosphate, dissolved organic phosphorus and silicate) and chlorophyll-a along a salinity gradient in the tropical Cachoeira River estuary, subject to the untreated effluents of a sewage treatment plant (STP). During the study period the lowest and highest river discharge occurred in February and April 2010, respectively. High river outflow promoted increased concentrations of inorganic nitrogen and silicate but did not affect the concentration of phosphate. Based on the chlorophyll-a concentration the estuary may be classified as eutrophic / hypereutrophic in its inner portion and mesotrophic in the lower region. The inner portion is more affected by the nutrient load carried out by the river and STP, while dilution by seawater contributed to the reduction of the nutrient concentrations in the lower reaches of the estuary. The results indicate that nutrient uptake by the phytoplankton is the most effective dissolved inorganic nutrient removal processes, especially for phosphate. Mixing diagrams suggest that the coupling of nitrification and denitrification processes is also responsible for the elimination of nitrogen from this ecosystem. R E S U M OCampanhas de amostragens mensais foram realizadas entre fevereiro de 2010 e janeiro de 2011 para avaliar a distribuição espacial e temporal de nutrientes (amônia, nitrito, nitrato, nitrogênio orgânico dissolvido, fosfato, fósforo orgânico dissolvido e silicato) e clorofila-a, ao longo do gradiente de salinidade no estuário tropical do Rio Cachoeira. Este estuário é sujeito aos efluentes de esgotos não tratados de uma estação de tratamento de esgoto (ETE). No período estudado a maior e menor vazão do rio ocorreram em fevereiro e abril de 2010, respectivamente. A alta vazão do rio promoveu aumento das concentrações de nitrogênio inorgânico e silicato, mas não afetou as concentrações de fosfato. Baseado nas concentrações de clorofila-a, o estuário pode ser classificado como eutrófico/hipereutrófico na porção interna e mesotrófico na região externa. A porção interna é mais afetada pela carga de nutrientes do rio e da ETE, enquanto a diluição pela água marinha contribuiu para diminuir as concentrações de nutrientes na porção externa. Os resultados indicam que a absorção de nutrientes pelo fitoplâncton é o processo mais eficiente na remoção desses nutrientes, especialmente do fosfato. No entanto, os diagramas de mistura sugerem que a nitrificação e denitrificação acopladas no rio também são responsáveis pela eliminação do nitrogênio do ecossistema.
