DSM, a large chemical company in the Netherlands, operates a plant for the biological treatment of the wastewater of about 35 production plants (organic and inorganic chemicals). A special feature of this biotreatment plant is complete nitrification of Kjeldahl-nitrogen, in combination with denitrification. Experiences with this installation are reported. A serious odour problem has arisen due to the presence of traces of a tellurium-containing catalyst from one of the plants. An organic tellurium compound with a very low odour threshold is produced in the wastewater treatment plant, mainly under anoxic, dentrifying conditions. Experimental results on the origin of the problem are reported, and a solution is given.

At both two-stage activated sludge treatment plants of the city of Frankfurt an almost complete nitrification is achieved. Upgrading of the plants is required to ensure denitrification. As an alternative for implementing a solution according to the German ATV-Standard A 131 separate denitrification by an upflow fluidized-bed technology was thoroughly investigated on pilot plant scale. The results show, that a far-reaching denitrification can safely be obtained by this process. Equations for quantifying the volumetric denitrification capacity of the bed (kg ΔN/m3·d) and the effluent nitrate concentration are derived for process design. The denitrification efficiency of the system, its benefits and disadvantages are discussed together with economical aspects.

Abstract:Phosphorus is a major substance that is needed especially for agricultural production or for the industry. At the same time it is an important component of wastewater. At present, the waste management priority is recycling and this requirement is also transferred to wastewater treatment plants. Substances in wastewater can be recovered and utilized. In Europe (in Germany and Austria already legally binding), access to phosphorus-containing sewage treatment is changing. This paper dealt with the issue of phosphorus on the sewage treatment plant in Nitra. There are several industrial areas in Nitra where record major producers in phosphorus production in sewage. The new wastewater treatment plant is built as a mechanicalbiological wastewater treatment plant with simultaneous nitrification and denitrification, sludge regeneration, an anaerobic zone for biological phosphorus removal at the beginning of the process and chemical phosphorus precipitation. The sludge management is anaerobic sludge stabilization with heating and mechanical dewatering of stabilized sludge and gas management. The aim of the work was to document the phosphorus balance in all parts of the wastewater treatment plant - from the inflow of raw water to the outflow of purified water and the production of excess sludge. Balancing quantities in the wastewater treatment plant treatment processes provide information where efficient phosphorus recovery could be possible. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. There are also two outflows - drainage of cleaned water to the recipient - the river Nitra - 9.9 kg Ptot/day and Ptot content in sewage sludge - about 120.3 kg Ptot/day - total 130.2 kg Ptot/day.
