“…One promising area is the immobilization and simultaneous use of both denitrifying heterotrophic and autotrophic sludges. Sumino et al [37] has reported the enhanced denitrification by the inclusion of both immobilized anaerobic ammonia oxidization (ANAMMOX) sludge and heterotrophic sludge. Their wastewater contained both nitrate and ammonia; the heterotrophic sludge both consumed nitrate and produced nitrite.…”

Nonpoint source nitrogen is recognized as a significant water pollutant worldwide. One of the major contributors is agricultural drainage line water. A potential method of reducing this nitrogen discharge to water bodies is the use of immobilized denitrifying sludge (IDS). Our objectives were to (1) produce an effective IDS, (2) determine the IDS reaction kinetics in laboratory column bioreactors, and (3) test a field bioreactor for nitrogen removal from agricultural drainage line water. We developed a mixed liquor suspended solid (MLSS) denitrifying sludge using inoculant from an overland flow treatment system. It had a specific denitrification rate of 11.4 mg NO 3 -N g −1 MLSS h −1 . We used polyvinyl alcohol (PVA) to immobilize this sludge and form IDS pellets. When placed in a 3.8-L column bioreactor, the IDS had a maximum removal rate (K MAX ) of 3.64 mg NO 3 -N g −1 pellet d −1 . In a field test with drainage water containing 7.8 mg NO 3 -N L −1 , 50% nitrogen removal was obtained with a 1 hr hydraulic retention time. Expressed as a 1 m 3 cubically-shaped bioreactor, the nitrogen removal rate would be 94 g NO 3 -N m −2 d −1 , which is dramatically higher than treatment wetlands or passive carbonaceous bioreactors. IDS bioreactors offer potential for reducing nitrogen discharge from agricultural drainage lines. More research is needed to develop the bioreactors for agricultural use and to devise effective strategies for their implementation with other emerging technologies for improved water quality on both watershed and basin scales.

Previo a cada experimento, los digestores se llenaron con una mezcla de lodo: efluente (fracción particulada: fracción disuelta) en una proporción 1:4 (Rustrian et al, 1997;Sumico et al, 2006).

RESUMEN. Los sistemas de recirculación acuícola producen efluentes (fracción disuelta y fracción particulada) con altas concentraciones de nitrógeno y fósforo que son una fuente potencial de contaminación si no se tratan en forma adecuada. El tratamiento de los lodos y remoción de nutrientes por medio de la digestión anaeróbica se ha vuelto una alternativa viable para la reducción y la estabilización de los lodos provenientes de los sistemas de recirculación acuícola. El presente estudio determinó el efecto de cuatro diferentes pretratamientos (alcalino, mecánico, térmico y biológico) en la reducción de los lodos, la desnitrificación, la producción de biogás y la dinámica del nitrógeno y el fósforo proveniente de los efluentes de un cultivo de tilapia nilótica (Oreochromis niloticus, Linnaeus, 1758) en condiciones hiper-intensivas con experimentos mensuales durante un año, con duración de 15 días cada uno. Tras la aplicación de pretratamientos en los lodos de origen acuícola, se obtuvo un aumento en la liberación de nitrógeno amoniacal total con respecto al control, de igual forma se obtuvo una remoción de nitritos en todos los pretratamientos (˃90%), se incrementó la remoción de sólidos suspendidos totales, siendo mayor en los pretratamientos (˃20,3%) en comparación con el control (14,6%), así como también se incrementó la producción de biogás, siendo el pretratamiento biológico donde se obtuvo la mayor concentración (45,18 cm 3 L -1). Esto indica que la aplicación de pretratamientos en los efluentes acuícolas mejora los procesos de desnitrificación y digestión anaeróbica, pudiendo reducir los tiempos de retención hidráulica. Palabras clave: desnitrificación, digestión anaeróbica, pretratamientos, efluentes, sistema de recirculación. Effect of four different pretreatments in anaerobic digestion and nutrientremoval of effluents from a recirculating aquaculture system ABSTRACT. Intensive aquaculture recirculating systems produce effluents (dissolved and particulate solids) with concentrations of nitrogen and phosphorus, a potential source of pollution if they are not properly treated. The sludge and nutrient removal by anaerobic digestion has become an alternative for aquaculture sludge digestion and stabilization. In this study we determine the effect of four different pretreatments (alkaline, mechanical, thermal and biological) in sludge reduction and denitrification efficiency, biogas production and nitrogen and phosphorus dynamics from a hyper-intensive Nile tilapia (Oreochromis niloticus, Linnaeus, 1758) culture in 15 days experiments, one per month for one year. After application of pretreatments in aquaculture sludge, an increase in the release of total ammonia nitrogen was obtained with respect to the control, in the same way nitrate removal was obtained in all pretreatments (˃90%), The increase in total suspended solids removal was higher in pretreatment (˃20.3%) compared to control (14.6%), As well as the biogas production increase, being the biological pre-treatment where the highest concentration was ...

“…Nitrates and nitrites in water supplies have led to cases of infant methaemoglobinaemia, mutation of DNA and gastric cancer. They can also contribute to eutrophication of water bodies [10, [14][15][16]. The most important parameters with an important influence on the denitrification process are the nitrate content, g COD/g N-NO 3 ratio, type and concentration of carbon source and the pH [17,18].…”

This laboratory research was carried out to evaluate the performance of a multistage anaerobic biofilm reactor, with six compartments and a working volume of 70 L, for the treatment of a strong synthetic nitrogenous and high-strength wastewater at an operational temperature of 26ºC ± 0.5ºC. Initially, the performance of the reactor was studied when subjected to an increase in the hydraulic retention time (HRT) at a constant influent COD concentration of 10000 mg/L. Five different HRTs were studied: 0.25, 0.67, 1, 3 and 5 days, which were equivalent to 6, 16, 24, 72 and 120 hours, respectively . By increasing the HRTs from 6 h to 1 day, COD and BOD removal efficiencies were increased from 63% to 84% and from 66% to 87%, respectively. Moreover, at an HRT of 3 days, COD and BOD removal efficiencies were equal, reaching 93%. In the second phase of the research, the effect of adding nitrate with a concentration of 3000 mg/L at an influent organic loading rate of 10 g COD/L·day was researched on the reactor performance and the amount of biogas produced. Denitrification took place almost solely in the first three compartments of the reactor, with efficiencies of 85%, 95% and 98%, respectively. The nitrite produced was only detected in the first and second compartments at concentrations of 138 mg/L and 24 mg/L, respectively. In addition, no accumulation of nitrite was detected in the reactor. Furthermore, the denitrification caused an increase in the total volume of produced biogas from 102 L/d to 178 L/d.
