Book Description
Uno de los problemas frecuentes de las granjas lecheras es su alto consumo de agua para su operacion, misma que a su vez se convierte posteriormente en residual, la cual generalmente es vertida cruda al ambiente, causando graves problemas de contaminacion. El presente documentos presenta un caso practico de exito, en el cual se aplica la digestion anaerobia para tratar dichas aguas, para tal fin se utilizan dos reactores de lecho fijo (RALF), y se compara el rendimiento de cada uno utilizando en uno de ellos zeolitas en el material de relleno. Obteniendose que para el reactor con zeolitas la remocion de la DQO fue de 80% y de la DBO de 78,9% en un tiempo de retencion hidraulico de 6 dias, mientras que para el caso sin zeolitas la remocion de la DQO fue de 69% y de la DBO fue de 77,1% para el mismo tiempo de retencion. Estos datos permiten determinar que utilizando esta tecnologia es posible tratar sustancialmente el agua residual de esta actividad de un modo sencillo y economico si se compara su costo con el de otras tecnologias existentes."

Book Description
El presente libro es resultado de una investigación que expone las consideraciones técnicas y científicas para el diseño de un nuevo reactor aeróbico modificado a flujo pistón y un sedimentador de flujo helicoidal para la remoción de contaminantes presentes en las aguas residuales. El reactor biológico aeróbico y el sedimentador antes mencionados fueron evaluados y operados en planta piloto, y de esta manera se obtuvieron resultados favorables para la descontaminación del agua.

Book Description
In 1982 the International Association on Water Pollution Research and Control (IAWPRC), as it was then called, established a Task Group on Mathematical Modelling for Design and Operation of Activated Sludge Processes. The aim of the Task Group was to create a common platform that could be used for the future development of models for COD and N removal with a minimum of complexity. As the collaborative result of the work of several modelling groups, the Activated Sludge Model No. 1 (ASM1) was published in 1987, exactly 25 years ago. The ASM1 can be considered as the reference model, since this model triggered the general acceptance of wastewater treatment modelling, first in the research community and later on also in practice. ASM1 has become a reference for many scientific and practical projects, and has been implemented (in some cases with modifications) in most of the commercial software available for modelling and simulation of plants for N removal. The models have grown more complex over the years, from ASM1, including N removal processes, to ASM2 (and its variations) including P removal processes, and ASM3 that corrects the deficiencies of ASM1 and is based on a metabolic approach to modelling. So far, ASM1 is the most widely applied. Applications of Activated Sludge Models has been prepared in celebration of 25 years of ASM1 and in tribute to the activated sludge modelling pioneer, the late Professor G.v.R. Marrais. It consists of a dozen of practical applications for ASM models to model development, plant optimization, extension, upgrade, retrofit and troubleshooting, carried out by the members of the Delft modelling group over the last two decades.
