Descripción de tecnologías híbridas para el tratamiento de agua residual doméstica

Abstract

The present monograph addresses the revision at the technological level of the different hybrid reactors for the treatment of domestic wastewater, in such a way that it allows to answer the research question related to the selection of a hybrid reactor for the treatment of domestic wastewater in a Colombian context. A methodology was used that consisted first in describing the different hybrid technologies for the treatment of domestic wastewater, where anaerobic, biological, UASB, among others, can be found; also, the different design criteria of each reactor were analyzed to identify and recognize the minimum requirements for their construction. It is important to mention that in Colombia there are very few cases where this type of reactors have been implemented because they require constant monitoring to avoid the generation of bad odors and their operation can be slow. However, the main results obtained during the elaboration of this document allowed to determine that these reactors could be a great alternative in terms of domestic wastewater treatment since according to consultations made indifferent bibliographic sources they can eliminate COD of approximately 70% and 48% (Lew, 2004) and elimination of BOD between 70% to 91% (Banu, 2007) emphasizing that generally they are of low cost, of equal form they have the capacity to be adapted in any thermal floor and finally they have the possibility of combining with other reactors improving their operation as opposed to the water treatment.
