The Use of Advanced Oxidative Processes and the Toxicity of Textile Effluent

The textile industries are important in a country's economy due to the generation of resources and constitute industries that consume a lot of water, producing potentially polluting liquid effluents. Among the toxic substances dumped in recipient bodies, dyes stand out. Several studies seek to develop efficient forms of treatment, whether biological or chemical. Advanced oxidative processes are among the most widely researched chemical treatments. Toxicity tests are used in order to verify the effectiveness of these treatments before the discharge of treated effluents into the environment. Effluent toxicity is tested with a number of organisms. In this work, the objective was to verify the efficiency of the Foto-Fenton process and to verify the toxicity using lettuce seeds, before and after the advanced oxidative treatment, the effluent analyzed was from a textile industry for processing jeans from the rough of Pernambuco, belonging to the Arrangement Local Productive. However, there was a reduction in the toxicity of the textile effluent after treatment.
