Estudio de la efectividad de una nueva configuración tecnológica de tratamiento de aguas residuales, lodos activados plus (La+) : combinación de un biorreactor de membranas y ozonización, desarrollado para reducir la producción de purga de lodos y mejorar la calidad de aguas tratadas
(Universidad de Chile, 2014)
el mejoramiento de la calidad del agua tratada obtenida. La línea base se estableció con un sistema de lodos activados convencional (LAC) y se evaluaron los efectos de cada técnica metabólica por separado mediante ozonización (LAO3) y un biorreactor...
The reduction of excess sludge production and the generation of potentially reusable water in wastewater treatment plants is critical in a scenario where there is water scarcity. In this context the aim of this work was to evaluate the effect produced by the combination of lysis-cryptic growth (ozonation) and maintenance metabolism (membrane bioreactor) strategies, both of them defining parts of the AS+ technology, in terms of efficiency in minimizing sludge production and improving the quality of obtained treated water. The baseline was established with a conventional activated sludge system (CAS) and the effects of each metabolic technique were evaluated separately during ozonation (ASO3) and while using a membrane bioreactor (MBR). The results showed that with a doses of 0,04 gO3/gSSTo or 0,01 gO3/h*[SSVo], the AS+ system was superior to CAS, ASO3 and MBR systems, complying with the established limits for all parameters given by the DS 90 when evaluated for the quality of the generated treated water and also AS+ achieved a excess sludge production 75% lower than CAS, producing 0,22 gSSV/d v/s 0,88 gSSV/d...

Aguas residuales municipales y su reutilización para riego agrícola en Chile
(Universidad de Chile, 2022)
El actual contexto de cambio climático y sequias sostenidas en regiones áridas y semiáridas del planeta durante las últimas décadas, hacen que la preocupación por la disponibilidad del agua se convierta en una temática relevante en la gestión...
In the current context of climate change and a global record of sustained drought in the arid and semi-arid regions of the planet in recent decades, the availability has become an increasingly important issue in the political, institutional, private, and civic management of water resources. In addition, international projections estimate an increase in general water demand as a result of an increase in the world’s population in coming decades. With this, it is estimated that access to water will be a limitation for the development of agriculture in the future with a lower supply available for this productive sector. The reuse of domestic wastewater in productive activities, especially agriculture, has become an increasingly common activity worldwide as a sustainable alternative to face the hydric panorama. The use of wastewater as a new source of water for agricultural irrigation makes it necessary to know its composition, dynamics of these with the soil, plants and consumers; the effects that these can have on production, public health and environment. The use of wastewater in agriculture corresponds to a complex issue of great scope, which deserves the active participation of the State for its safe and efficient use, with a regulatory framework that manages their correct development. This research consists of a bibliographic review of the main considerations for the reuse of wastewater in agricultural irrigation and how these apply to the current Chilean regulatory framework under an analytical vision that envisions potential challenges for the future....

" Índices de calidad de agua como herramienta para la evolución de aguas superficiales: caso de estudio rio Lluta"
(Universidad de Chile, 2014)
Un índice de calidad de agua (lCA), consiste básicamente en una expresión simple de
una combinación más o menos compleja de un número de parámetros que puede ser

A water quality index, is basically a simple expression for a more or less complex number of parameters that can be represented by a number, a range, a verbal descr¡pt¡on, a symbol or a color combination. The main object¡ve of this study is to applicate different waler qual¡ty indexes to Lluta river as a tool for the evaluation of surface water. To this purpose data bases obta¡ned from water qual¡ty stat¡ons Lluta of General Water Direction at Lluta river (Colpitas in Alcérreca, Caracarani in Alcérreca, Lluta in Tocontasi and Lluta ¡n Panamerican) were used. According to the historical database of the area ii is evident that the amount of boron and arsenic in the Lluta river water actually exceeds the Ch¡lean quali§ standard for irrigation (NCh 1333), being su¡table only for irrigation of tolerant species in th¡s env¡ronment. Several water quality indexes were compared s¡mpl¡f¡ed ¡ndex of water quality (ISQA) of Spain, CCME-WQI (Canadian Counc¡l of Ministers of ihe Env¡ronmeni - Water Quality lndex) of Canada and the index of water quality Cade-ldepe of Ch¡le, in order to f¡nd the most adequate for Lluta river. The results show that the CCME-WQI Canada is better than other indexes as it presents a structure calculation that allows a wider, comprehensive evaluation of water quality, since ii considers the variaiion in t¡me and space. ln its application it is not necessary io adopt speciflc parameters for calculation, but leaves open the choice of them to the good professional cr¡ter¡a and ¡n agreement with ihe current Chilean standard trial. With the flexibility given by the index it is easier to perform an analysis in areas where monitor¡ng variables are bounded. INDICE INTRODUCCIÓN ........1 'l .5 Objetivos específicos ......
