Análisis de un sistema de tratamiento de aguas grises procedentes del inodoro con el uso de técnicas alternativas en viviendas unifamiliares en la parroquia Atahualpa, cantón Ambato, provincia de Tungurahua

Abstract

The present experimental work began with the investigation of several alternatives for the treatment of gray water from the toilet, among the most viable were: the application of wetlands with aquatic microphytes, latrine wells and finally a dry toilet system, which was chosen to carry out the research due to the low consumption of drinking water involved in the treatment. This technique consists of separating feces and urine from their source to be able to treat them separately, thus maintaining an ecological and low-polluting system for aquifers. The treatment to significantly reduce the pathogenic microorganisms present in the feces was dehydration, which led to a 25 percent decrease in the moisture content present in them. To improve the efficiency of the system, a flat type collector was incorporated which occupies the solar radiation in order to increase the temperature inside, in addition, two types of covering material were used: wood shavings and lime, managing to increase the drying speed. Regarding the treatment of urine, it was not necessary to carry out an advanced method, it was only enough to keep it stored for a period of time, since the urine located in the bladder does not have pathogens that can transmit diseases. The results obtained in the research show that it is possible to implement this type of system in single-family homes that have shortages of drinking water, as long as the users agree.
