Full textThree main research axes were held during my PhD: The study of nitrification kinetics at full scale and in batch; study of releases and uptake kinetics of phosphate; the evaluation of the interest of ORP measure for control of nitrification, denitrification and enhanced biological phosphorus removal. The study at full-scale as well as the batch experiments have proved that, for a sufficient sludge age, the nitrification rate, expressed per liter of sludge, varies slightly with the sludge concentration, within 2 to 4. 5 g/l VSS. A higher sludge concentration does not implicate a higher nitrification capacity. Batch tests were realised to determine the influence of both COD concentration and anaerobic residence time on both phosphate release and uptake rates. The phosphor-release rate, settled on the first anaerobic hour, was proportional to the initial filtered COD concentration. For the same COD concentration, an increase of the anaerobic residence time superior to 2h did not increase the excess phosphorous uptake and did not improve the enhanced biological phosphorus removal efficiency. A second series of experiences were realised to specify the appearance conditions and the consequences on biological phosphorus removal of a second P-release (a release without carbon supply). An occasional secondary P-release does not seem to affect the biological phosphorus removal process

Full textTwo pilot-scale studies were carried out to asses system performances for COD alimentation, nitrification and denitrification. The system consisted principally of two percolating filters with Cloisonyle plastic media, an intermediate setting tank, an anoxic tank and a final tank setting tank. In the first study, the anoxic tank was placed between the first filter and the intermediate setting tank. A total recycle rate was applied at this level. The system was operated for 11months at Pierre Bénite municipal sewage near Lyon, receiving a settle affluent from the primary sedimentation tank of this station. In the second study, the anoxic tank was placed after de second filter without total recycle. The system functioned for 14 month in laboratory, Fed with non-characteristic local sewage with the addition of abattoir plasma. .

Full textThe present study was conducted to establish the nitrogen removal capacity for a domestic effluent of the submerged fixed-film process BIO-FOSSEMD. This process has been especially designed for small communities and is based on the use of textile as bacterial support. When aerated continuously and subjected to loads of 35 g N-NH4+ m-2 d-1 and 323 g DBO5 m-2 d-1, this process reached 96% of nitrification, while providing 98% biological oxygen demand removal and 91% suspended solids removal. Under these conditions, values lower than 2 mg N-NH4+/L were measured on a regular basis in the effluent. When the reactor is operated under intermittent aeration, NH4+ and NO3- removal efficiencies depend on the duration of aerobic and anoxic periods. With a 24 h cycle, including 75% of aeration, the effluent nitrogen concentrations varied from 0,4 to 7,4 mg N-NH4+/L and from 10 to 21 mg N-NO3-/L. Under continuous aeration, total nitrogen removal average was around 49%, reaching over 70% at some point. Similar nitrogen removal was reached under intermittent aeration. Kinetic tests conducted ex situ gave a maximal nitrification rate of 58 g N-NH4+ m-2 d-1 and a maximal denitrification rate of 52 g N-NO3- m-2 d-1.

Full textIn order to maximize the urban wastewater treatment, particularly under wet weather, the operational conditions allowing an improvement of the carbon and nitrogen removal efficiency were sought out. An activated sludge wastewater treatment plant with an intermittent aeration tank was modeled with the Activated Sludge Model 1. As a preliminary step, the plant was intensively sampled by means of three measuring campaigns (several days long) realized under different temperatures and hydraulic loads. The collected data allowed to calibrate the model parameters at 12°C and at 20°C under dry weather on the saine plant. The model parameters were then validated at 14°C under overload conditions. Meanwhile, the influent was characterized in terms of biodegradation kinetics of COD, under various sampling rainfail conditions. This COD characterization is required for model forcing. A respirometric procedure was developed and applied to samples collected from the combined and separate sewers of the plant. The evaluation of COD fractions is also of interest to predict the impact and the hehaviour of direct combined sewer overflows on the receiving body. By means of mass balance calculations, we assessed the contribution of each biological zone in the COD and N removal by using the validated model. Each zone interest and the impact of operating and external conditions (temperature, load) on the biological treatment were investigated through several simulation scenarios. We deterrnined that the maximal pollutant load that can be treated essentially depends on the temperature and the influent composition (COD/N ratio in particular). In all cases, the maximization of the treatment relies on the adjustment of the operational conditions
