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
Humedales para tratamiento es el séptimo volumen de la serie “Tratamiento biológico de aguas residuales” (en inglés “Biological Waste Water Treatment Series”), que provee una presentación de vanguardia sobre la ciencia y tecnología del tratamiento de aguas residuales. Los principales tipos de sistemas de humedales son tratados en este volumen, a saber: (i) Humedales de flujo subsuperficial horizontal, (ii) Humedales de flujo vertical; (iii) Humedales de flujo vertical tipo francés; (iv) Humedales intensificados; (v) Humedales de flujo libre; (vi) otras aplicaciones de los humedales para tratamiento. El libro presenta en forma clara y didáctica, los conceptos básicos, los principios de la tecnología, desempeños esperados, criterios de diseño, ejemplos de diseño, aspectos constructivos y guías para la operación. El libro ha sido escrito en su versión inglesa, y traducido al castellano, por un equipo internacional de expertos en el campo de los humedales para tratamiento.

Book Description
Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Book Description
Environmental nanotechnology is considered to play a key role in shaping of current environmental engineering and science practices. This book titled "Environmental Nanotechnology" covers the advanced materials, devices, and system development for use in the environmental protection. The development of nano-based materials, understanding their chemistry and characterization using techniques like X- Ray diffraction, FT-IR, EDX, scanning electron microscope (SEM), transmission electron microscope (TEM), high resolution-TEM, etc is included. It also highlights the scope for their applications in environmental protection, environmental remediation and environmental biosensors for detection, monitoring and assessment. Key Features: Covers basic to advanced Nano-based materials, their synthesis, development, characterization and applications and all the updated information related to environmental nanotechnology. Discusses implications of nanomaterials on the environment and applications of nanotechnology to protect the environment. Illustrates specific topics such as ethics of nanotechnology development, Nano-biotechnology, and application in wastewater technology. Includes applications of nanomaterials for combating global climate change and carbon sequestration. Gives examples of field applications of environmental nanotechnology.

Book Description
The treatment of contaminated soil is a permanently relevant subject for ensuirng the quality of the environment. A wide variety of soils contaminated witht a broad range of harmful chemical compounds all around the the world, call for many different treatment strategies. Research activities focus on affordable methods offering the greatest possible effect, whilst limiting the potential side effects. This book sums up the research activities of Research Centre 188 which has cooperated with the Technical University of Hamburg-Harburg, the University of Hamburg and GKSS in Geesthacht over the last 12 years, thus greatly advancing our knowledge in this field.
