PRODUCTION FROM INDUSTRIAL EFFLUENTS

Industrial activities are major generators of solid organic waste and liquid effluents which, due to environmental preservation principles, need to be treated before disposal to avoid pollution. This waste has a high organic matter content, which makes it a potential substrate for biogas production. The aim of this work is to assess the potential for biogas production from a mixture of industrial effluents from different industries, using a batch system. Samples of substrate and inoculum were collected at the Maringaense Wastewater Treatment Company, after which their physical and chemical characteristics were determined. The biogas was quantified by measuring the volume produced each day, and its composition was determined using a gas chromatograph. After the tests, the highest biogas and methane yields were 721.29 NmL gSV-¹ and 461.69 NmL gSV-¹, respectively.
