Wastes Flow from wastewater treatment in the industrial sector of Cali urban and periurban area, free trade zone of Palmira and Yumbo

(Spa) Este trabajo presenta la investigación realizada en cuanto al manejo de residuos (conocidos para este caso como lodos y grasas) provenientes del tratamiento de aguas residuales industriales y domésticas de empresas ubicadas e n la zona industrial de Cali, zona urbana y periurbana, y zona franca del municipio de Palmira y Yumbo. Se desarrollaron dos etapas cuyos objetivos fueron respectivamente: 1) identificar los generadores de lodos y grasas, y 2) evidenciar las prácticas de m anejo por parte de los gestores (empresas que prestan el servicio de mantenimiento, recolección o tratamiento a los residuos generados). Finalizando estas etapas, se elaboró el flujo de estos residuos en la zona de estudio. Lo anterior permitió obtener un compilado de datos que describe la forma en que ocurre el manejo de este tipo de residuos para generar una visión de la problemática en el Valle del Cauca, como base para futuras investigaciones en torno a dar soluciones técnicas para manejo de estos resid uos. Para el año 2014, en la zona de estudio se encontraron alrededor de 921 industrias, de las cuales 85 tenían sistemas de tratamiento de aguas residuales (por lo tanto, son generadoras de residuos). Por otra parte, se encontraron 28 empresas gestoras de residuos. En esta investigación participaron voluntariamente 22 empresas generadoras y 10 gestoras. El volumen aproximado de lodo y grasa que generan estas empresas es 368 toneladas por mes. De esta cantidad, solo 159 toneladas por mes (43 %) es aprovecha do como acondicionador de suelos, abono, humus o para sustitución de materias primas. A pesar de que un buen porcentaje de lodo es aprovechado, como conclusión se identificó que se requieren políticas ambientales que incentiven estas alternativas para redu cir los impactos sobre el ambiente(Eng) This paper presents the research carried out regarding the management of waste (known in this case as sludge and grease) from the treatment of industrial and domestic wastewater from companies located in the industrial zone of Cali, urban and peri-urban area, and free trade zone. municipality of Palmira and Yumbo. Two stages were developed whose objectives were respectively: 1) to identify the generators of sludge and grease, and 2) to demonstrate the management practices by the managers (companies that provide the service of maintenance, collection and / or treatment of waste generated). At the end of these stages, the flow of these wastes was elaborated in the study area. This allowed us to obtain a compilation of data that describes the way in which the management of this type of waste occurs to generate a vision of the problem in the Valle del Cauca, as a basis for future research on providing technical solutions for handling these. For the year 2014, around 921 industries were found in the study area, of which 85 had wastewater treatment systems (therefore, they are waste generators). On the other hand, 85 waste managers were identified. In this research, 22 industries accepted to participate as well as 5 waste managers. The approximate volume of mud and grease generated by these companies is 367.89 ton / month. Of this amount, only 158.7 ton / month (43%) is used as a soil conditioner, fertilizer, humus or for the substitution of raw materials. In spite of some of the sludge is used, in conclusion, it was identified that environmental policies are required that encourage these alternatives to reduce the impacts on the environmen

Flujo de Residuos del Tratamiento de Aguas Residuales en el sector industrial de Cali zona urbana y periurbana, zona franca de Palmira y Yumbo

Research, Innovation and Extension to the service to society, in the framework of the Sixth Conference on Social Appropriation of Knowledge (SAK)

Annually, the Technological University of Pereira has been carrying out some events in the line of Social Appropriation of Knowledge. This has been done through the research, innovation, and extension Vice Rectory, moreover, these sessions are framed within the institutional objective: “Define and direct the guidelines for the institutional research that strengthen the research groups and the Seedbeds, through the formation of researchers, the development of science, technology, and innovation projects or programs, as well as the generation of networks and strategic partnerships that contribute to the creation and appropriation of knowledge for the society”. Therefore, the 6th Social Appropriation of Knowledge event took place under the title of “The research, Innovation, and Extension at the service of society” which was constituted as an academic and institutional opportunity where the results of the research projects from the last 5 years were published. The results of this event revealed, once again, the high academic level in investigation development at the university. There were 11 articles divided into 6 fields: Health, Engineering, Technology, Education, Industrial Technology, and Art, in which the results obtained by the research projects from the investigation groups were shown, promoting a knowledge exchange from their authors whose intellectual formation is diverse. With this publication, as part of a permanent effort to socialize the knowledge, the university promotes the circulation of its professors, students, and general community voices, having in mind that knowledge must be transferred through different channels, strengthening the academy and society in general, according to the institutional mission that invites us to incentivize a research culture in the university community.Presentation........................................................................................................... 5 Chapter 1.
