The purpose of this research was to evaluate the removal of nitrogen compounds found in petroleum industry wastewater, by employing a biologic process with fungi. During 156 days, two aerobic biologic reactors with fungi (BRF), with immobilized biomass and continuous up flow were built and operated. Both reactors were made in acrylic and presented identical dimensions height 60 cm, 10 cm diameter and 4,5 L liquid volume. The first reactor (R1) had polyamide bed as support medium and the second one (R2) used polyurethane foam. Initially, the reactors containing the wastewater were inoculated with 2 x 106 spores.mL-1, of Aspergillus niger AN 400. They remained in rest, with no aeration, for 24 h mycelium growth. After this period, the aeratio...
