“…Nitrite concentrations were less than 0.05 mg NO 2 -N/L at each stage in the influent and effluent. Nitrite concentration in the effluent of an AGS process fed with synthetic municipal wastewater was found less than 0.06 mg NO 2 -N/L (Kosar et al 2022b ). Nitrate concentration in the effluent was 15.4 ± 1.1 mg NO 3 -N/L at Stage 1, whereas it was 9.9 ± 0.8 mg NO 3 -N/L at Stage 2.…”

Recently, one of the main purposes of wastewater treatment plants is to achieve a neutral or positive energy balance while meeting the discharge criteria. Aerobic granular sludge (AGS) technology is a promising technology that has low energy and footprint requirements as well as high treatment performance. The effect of co-treatment of municipal wastewater and food waste (FW) on the treatment performance, granule morphology, and settling behavior of the granules was investigated in the study. A biochemical methane potential (BMP) test was also performed to assess the methane potential of mono- and co-digestion of the excess sludge from the AGS process. The addition of FW into wastewater enhanced the nutrient treatment efficiency in the AGS process. BMP of the excess sludge from the AGS process fed with the mixture of wastewater and FW (195 ± 17 mL CH4/g VS) was slightly higher than BMP of excess sludge from the AGS process fed with solely wastewater (173 ± 16 mL CH4/g VS). The highest methane yield was observed for co-digestion of excess sludge from the AGS process and FW, which was 312 ± 8 mL CH4/g VS. Integration of FW as a co-substrate in the AGS process would potentially enhance energy recovery and the quality of effluent in municipal wastewater treatment. Graphical abstract

Adaptado de Kosar et al, (2022) Entre las características más importantes se presenta la concentración de la dosificación de aire que se requiere en base a la cantidad de sólidos suspendidos totales que hay en el efluente, además de sus dimensiones. Este tratamiento es capaz de disminuir un 4% el volumen total del efluente.…”

El diseño eficiente de un sistema de tratamiento de aguas residuales puede asegurar el correcto manejo del recurso hídrico utilizado en las diferentes industrias como en los laboratorios camaroneros, además de ayudar a preservar el medio ambiente. El presente estudio tuvo como objetivo dar a conocer los factores y parámetros que se deben considerar para realizar el diseño de un sistema de tratamiento en relación con la estimación de áreas, tiempos y costos. La metodología utilizada estuvo enfocada en la obtención de datos como el caudal de salida de una empresa de estudio, la definición del sistema de tratamientos a diseñar, la determinación de las maquinarias y concentraciones a considerar para los análisis respectivos, además de la generalización de los tiempos de tratamientos. Se efectuó diferentes métodos para analizar y estimar diferentes datos y compararlos con un diseño ya realizado por otro autor. Por último, se pudo concluir que las estimaciones realizadas ayudan a entender de forma clara los factores que se deben tomar en cuenta en el diseño de un sistema y su distribución de áreas, con el fin de evitar riesgos y de lograr la evacuación sostenible de las aguas residuales.

“…11 In addition, the maximum allowed amount of treated wastewater for urban and environmental uses is 1-2 mg L −1 . 12 There are various solutions, such as filtration, 13 sedimentation, 14 oxidation and reduction, 15 ion exchange, 16 adsorption, 17 and separation of membranes, 18 to reduce the amount of metal ions in effluents and wastewaters. The ability to remove most of the metals, high efficiency, and affordability of the adsorbent make adsorption an effective process for eliminating heavy metals from wastewater.…”
