MOBILE UNIT FOR FOR ASSESSING AND CONTROLLING THE IMPACT OF EFFLUENT FROM WASTEWATER TREATMENT PLANTS ON MARINE ECOSYSTEMS

摘要

The invention relates to a mobile unit for assessing and controlling the impact of effluent from wastewater treatment plants on marine ecosystems. The invention can be used to determine if the treatments applied to effluent from a given wastewater treatment plant are sufficient to obtain effluent that poses no potential risk to the marine ecosystem that will receive same. The invention can be used to perform variable-duration in situ toxicity tests, exposing different bioindicator species (from different taxonomic groups) to the effluent in real time with continuous water renewal. In addition, the invention allows different dilutions of the effluent to be established so as to simulate real effluent discharge concentrations and so that it is possible to determine quality guides and dilutions that would generate environmental risks in the receiving environment. The system is designed to control given variables (temperature, salinity, dissolved oxygen and photoperiod), preventing these variables from having an influence on the toxicological results.
