Abstract
The purpose of this article was to show the treatment capacity of bioreactors and their purification performance regarding the improvement of oxygen transfer by removing dissolved matter and suspended solids from domestic wastewater. For this purpose, three sets of tests were performed: Bacteria Adaptation in an aerated biological filter, Adsorption/Biosorption in anon-aerated Biological Filters and percolation in a trickling filter with three packed plastic media for evalued their performance. The results showed that for the adaptation tests DO concentration varied between 0.2 and 9 mg / L, which allowed a good aeration in the bioreactor. The removal performances of the organic material was 96.9% with an initial COD of 3200 mgO 2 /L, the turbidity has reached an abatement rate of 97.4% with an initial value of 625 NTU. For the Adsorption/Biosorption tests in a non-aerated Biological Filter, the performances of COD and turbidity reached a yield between 24 and 61%. For percolation, the yields found varied between 41 and 68% for the COD and turbidity. The OD concentration for his two tests varied from 0.2 to 1 mg/L. These results showed the use of several wastewater treatment techniques in a bioreactor.
