An increased interest in membrane filtration as water reclamation technology for industrial wastewater is observed. Disposal of the resulting concentrate remains however problematic. Our research project explores advanced oxidation processes as a way to treat concentrates generated by membrane filtration of complex industrial effluents. The project focuses on the implementation of eco-toxicological parameters in the process control of advanced oxidation processes. The presented research covers the toxicity of a typical complex effluent. Evaluation of toxicity and chemical parameters is used to determine if this effluent is suited as source for our future model concentrate. The toxicity of the effluent is determined using 5 different bio assays. The sensitivity of the assays is compared and the potential for environmental impact of the effluent is evaluated. The rapid V. fisheri luminescence inhibition assay is evaluated for its capability of replacing slower more accepted assays as a way to determine effluent toxicity.
