Resumen
La tesis consistiĆ³ en realizar un diseƱo de una planta de tratamiento de aguas
residuales para un proyecto de ampliaciĆ³n de un centro de cultivo de Smolt de
Salmones y Truchas, proyecto que ingresĆ³ al Sistema de EvaluaciĆ³n de Impacto
Ambiental a travĆ©s de una DeclaraciĆ³n de Impacto Ambiental, siendo evaluado por
todos los organismos fiscalizadores con incidencia ambiental.
El presente estudio consta de tres etapas:
1. Para determinar la eficacia de tratamiento de un decantador en operaciones de
la empresa Australis.
2. Para definir la normativa que se debe aplicar a un centro de cultivo que se
abastece de agua de vertiente.
3. Considerando estos resultados se elaborĆ³ el diseƱo definitivo y la valorizaciĆ³n
econĆ³mica de la planta de tratamiento.
El diseƱo consistiĆ³ en tres procesos que cumplen con las especificaciones
tĆ©cnicas de la SubsecretarĆa .de Pesca, las recomendaciones de la
Superintendercia de Servicios Sanitarios para sistemas de tratamiento de agua
residual, y las normas correspondientes a descargas de Residuos Industriales
LĆquidos a cursos o masas de aguas superficiales. Los dos primeros procesos de
tratamiento consistieron en filtraciĆ³n y posterior decantaciĆ³n, ambos fueron
especialmente diseƱados para reducir el 85% de los sĆ³lidos en suspensiĆ³n del
efluente. El tercer proceso para acumular y almacenar los sĆ³lidos retirados del
proceso de filtraciĆ³n.
El costo de implementar este proyecto en 1 O aƱos de operaciĆ³n fue avaluado en
U$ 0.0062 por Smolt producido, sobre la base de una producciĆ³n de 1.124.860
SmoltlaƱo, considerando el costo de la inversiĆ³n, los gastos de operaciĆ³n y
mantenciĆ³n.
The thesis comprised the designing of the waste water treatment plant for a Salmon and Trout smolt Farm center enlargement project, which was incresed to the environment lmpact Evaluation System through an environment impact Declaration (EID), this EID was evaluated by all of the govement departments concerned which the environment matters. The present study consist of three stages: 1. In order to determing the treatment efficiency of an actual decanter operating in Australis firm. 2. In order to define the regulations to be applied to a farm center, which rs supplied with spring water. 3. Taking into account this results, an economical study and final design of wastewater treatment plant was done. The design consisted in three process that match with: the technical specifications of the "subsecretaria de Pesca", the recommend dates of the SISS for waste water treatment systems and the norms applied to industrial waste water discharged to surface waters. The first two treatment process were filtration and subsequent decanter, both of them were designed specially to remove 85% of the effluent suspended solids. The third process was in order to accumulate and storage the solids coming from the filtration process. The investment cost of this project in a 1 O years operating basis was evaluated to be US $ 0.0062 per produced smolt per year, taking into account the operating and maintenance cost.
