Abstract
El presente trabajo de título consiste en una propuesta de mejora tecnológica al sistema de aguas de una planta papelera, específicamente al proceso de producción de papeles y cartones de embalaje a partir de fibra recuperada. Esta, busca implementar las Mejores Técnicas Disponibles (MTD) de la industria de celulosa y papel, en conjunto con tecnologías de tratamiento de aguas, con el objetivo de cerrar los circuitos de aguas de la fábrica. En base a la implementación del modelo, se consigue una reducción del 88% del consumo de agua fresca por tonelada producida, con respecto al consumo promedio del común de las plantas que fabrican papeles y cartones de embalaje. En cuanto a los efluentes liberados a los cuerpos de aguas receptores, se tiene que la propuesta consigue un proceso “0”riles, en condiciones normales de operación, facilitando un proceso productivo sustentable que entrega valor agregado a sus productos. Para el de desarrollo de la propuesta, se utiliza una metodología de trabajo basada en proyectos de mejora continua. Así, se define el proyecto, se establecen sus necesidades y requerimientos técnicos y se utilizan herramientas de análisis, con el objetivo de facilitar el diseño del sistema de tratamiento y reutilización de aguas.
The research project consists of a proposal based on technological improvement to the waters system of a paper mill, specifically to the production of packaging papers and cartons from recovered fiber. This proposal seeks the implementation of Best Available Techniques (BAT) of the cellulose and paper industry, together with waste water technology, aiming to close the factory’s water circuits. Based on the model implementation, 88% of fresh water consume can be reduced per produced ton, regards the average consumption of the common of thepaper mills that produce packaging paper and cartons. As to the effluents released to the water reception bodies, the proposal achieves a “0” waste water process, in normal operational conditions, facilitating a sustainable productive process, which provides benefit to its products. For the development of the proposal, a work methodology based on continuous improvement projects is used. In this way, the project can be defined, its needs and technical requirements are established, and analysis tools are used with the objective of facilitating the design of the treatment system and reutilization of waters.
