Book Description
Se propone un método de tratamiento terciario biológico. Para ello, se han realizado una serie de ensayos de depuración, utilizando aguas residuales que ya habían sido sometidas a un tratamiento secundario y una biomasa de algas unicelulares previamente cultivada. Los ensayos se realizaron en un periodo de diez días cada uno, midiéndose los siguientes parámetros: clorofila, ph, conductividad, nitratos, nitritos, amoniaco, cloruros, sulfatos, fosfatos, calcio, magnesio, dqo y alcalinidad. Se consideraron como variables la iluminación, la oxigenación, la retirada de biomasa y el control de ph. El estudio de estas variables, por separado, y después interrelacionadas entre si, revelo un mayor rendimiento del proceso en condiciones de luz, anaerobiosis, sin retirada de biomasa y sin control de ph. En estas condiciones, se realizaron varias experiencias, dando como resultado una disminución considerable de la mayoría de los parámetros medidos en forma de velocidad especifica. A partir de estas experiencias, se realizo un ejemplo de rendimiento, obteniendo altos porcentajes de eliminación, destacando los nitratos con 71.55%, la dureza con mas del 50%, los fosfatos con 99.4% y el amoniaco con 97%, con la importancia que ello trae consigo, a la hora de corroborar la validez de nuestro método, ya que son parámetros de un alto interés ecológico y sanitario.

Book Description
For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.
