Description of the project: "THE AIM OF THE PROJECT WAS THEORETICAL AND EXPERIMENTAL RESEARCH ON OXYGENATION PROCESS IN BIOLOGICAL WASTEWATER TREATMENT USING DIFFUSERS WITH ELASTOMER MEMBRANES IN THREE HYPOTHESIS: COUNTERCURENT FLOW, CO-CURRENT FLOW AND IMOBILE FLUID. IT HAS DEVELOPED MODELS FOR OXYGEN MASS TRANSFER, IT HAS STUDIED SIMILITUDE CRITERIA FOR MASS TRANSFER AND IT HAS MADE AN EXPERIMENTAL INSTALLATION. THEORETICAL RESULTS WAS COMPARED WITH EXPERIMENTAL ONES. "
