Ecological systems known as ECOSAN allow a complete recovery of almost all nutrients and mineral nutrients in wastewater after a separately appropriate treatment from feces, urine and greywaters contributing to reuse of biol in agriculture and bioenergy through biogas. The research was conducted in the retreat house El Milagro, located at 32 ½ Km of the Lima - Huarochirí highway in the Lurín river basin. The retreat house has an ecological sanitation system built in 2007. The blackwaters (mixture of feces, urine and toilet water) come from 15 toilets with an average flow of 362.5 liters per week. The agricultural wastes were composed of cavy manure and corn plant waste. Cavy manure was collected from the cavy farm (about 200 cavies) and corn plant wastes were collected from the fields of crops. Semi-continuous load of the biodigester was done every seven days and consisted of a mixtur...

In this study, it was evaluated the quality of biogas and biolwhich are produced in tubular bio-digesters of PVC with two different mixtures: one with a ratio of 1/4 between manure and water, and other with a ratio of 1/5. These biodigesters were installed for researching in the Model Center of Waste Treatment – CEMTRAR of Universidad NacionalAgraria La Molina. The monitoring and analysis of biogas and biol were conducted from November 2009 to April 2010. It reached an average of 52% of CH4and 37.4% of CO2in the mixture of ¼, and an average of 53% of CH4 y 36.9% de CO2in the mixture of 1/5. The obtained biol in the study has a good amount of N-P-K. The quantities of Ca, Mg and Na found in the mixtures are similar to the organic fertilizers; therefore they can be used as fertilizers in hydroponic crops. The biol in fecal coliforms reached an average of 6.08x103 NMP/100 ml y 1.27x103 NM...

El presente trabajo propone las acciones para integrar un sistema de gestión ambiental (SGA) con un sistema de gestión de calidad (SGC) existente en la empresa Vera & Moreno S.A., Consultores de Ingeniería. Se realizaron visitas a las instalaciones de la empresa a fin de evaluar el SGC con relación a la norma ISO 9001:2008 y la situación inicial en base a los requisitos de la norma ISO 14001:2004. También se identificaron y evaluaron los aspectos e impactos ambientales más significativos de la organización. A partir de ello, se definió el plan de integración, elaborándose la documentación del SIG, el Manual del SIG, la política de calidad y medio ambiente, los procedimientos, instructivos y formatos propios de la norma ISO 14001:2004. Finalmente, se llevó a cabo la fase inicial de la implementación del nuevo SGA, mediante la definición y ejecución de objetivos, metas...

Los ríos y quebradas, en la mayoría de casos, son utilizados como cuerpo receptor de los vertimientos municipales, que, sin el debido tratamiento, genera problemas de contaminación del agua. En las áreas de estudio de esta investigación, se tiene información de los monitoreos de calidad del agua publicadas por la Autoridad Nacional del Agua, donde los resultados no son muy comprensibles para una población que no conoce del tema. Los Índices de Calidad del Agua (ICA) son una de las herramientas más utilizadas para evaluar la calidad del agua, ya que resumen los datos de los parámetros fisicoquímicos y microbiológicos de una manera sencilla y de fácil comprensión. El objetivo de esta investigación fue realizar la evaluación de los ICA en las subcuencas Achamayo y Shullcas a través de la metodología canadiense CCME-WQI (The Canadian Council of Ministers of the Environment ...
