Summary: | Mobile unit for the evaluation and control of the impact of effluents from sewage treatment plants in marine ecosystems. By means of the invention it is possible to determine if the treatments to which the effluents of a certain wwtp are subjected are sufficient to obtain an effluent that does not suppose a potential risk for the marine receiving ecosystems. The invention allows carrying out in situ toxicity tests of variable duration, exposing different bioindicator species (from different taxonomic groups) to the effluent in real time with a continuous water renewal. It also offers the possibility of establishing different dilutions of the effluent with the idea of simulating the real concentrations of discharges and being able to determine quality guides and dilutions that would generate environmental risks in the receiving environment. The system is designed to control certain variables (temperature, salinity, dissolved oxygen and photoperiod) avoiding their influence on toxicological results.

Unidad móvil para la evaluación y control del impacto de efluentes de estaciones depuradoras de aguas residuales en ecosistemas marinos. Mediante la invención es posible determinar si los tratamientos a los que se someten los efluentes de una determinada EDAR son suficientes para obtener un efluente que no suponga un riesgo potencial para los ecosistemas marinos receptores. La invención permite realizar ensayos de toxicidad in situ de duración variable, exponiendo diferentes especies bioindicadoras (de distintos grupos taxonómicos) al efluente en tiempo real con una renovación continua de agua. Además, ofrece la posibilidad de establecimiento de distintas diluciones del efluente con la idea de simular las concentraciones reales de vertidos y poder determinar guías de calidad y diluciones que generarían riesgos ambientales en el medio receptor. El sistema está diseñado para controlar determinadas variables (temperatura, salinidad, oxígeno disuelto y fotoperiodo) evitando la influencia de las mismas en los resultados toxicológicos. |
