Benchmarking System

During a six-year period the Austrian Benchmarking System was developed. The main objectives of this benchmarking system are the development of process indicators, identification of best performance and determination of cost reduction potentials. Since 2004 this system is operated via an internet platform and automated to a large extent. Every year twenty to thirty treatment plants use the web-based access to this benchmarking platform. The benchmarking procedure comprises data acquisition, data evaluation including reporting and organised exchange of experience for the treatment plant managers. The process benchmarking method links the real costs with four defined main processes and two support processes. For wastewater treatment plants with a design capacity >100,000 PE these processes are further split up into sub-processes. For each (sub-) process the operating costs are attributed to six cost elements. The specific total yearly costs and the yearly operating costs of all (sub-)processes are related to the measured mean yearly pollution load of the plant expressed in population equivalents (PE110: 110 gCOD/d corresponding to 60 g BOD5/d)). The specific capital costs are related to the design capacity (PE). The paper shows the benchmarking results of 6 Austrian plants with a design capacity >100,000 PE representing approximately 30% of the Austrian municipal wastewater treatment plant capacity.

Operation Costs

This work aims to compare the operation costs (energy, reagents, waste management) for the three layouts usually used in wastewater treatment plants incorporating biofilters, using technical and economical data acquired during 10 years of operation of a Parisian plant (Seine Centre, 240,000 m3 d−1 –800,000 equivalent inhabitants). The final objective is to establish general economical data and tendencies that can be translated from our study to any biofiltration plant. Our results evidenced the savings achieved through the treatment process combining upstream and downstream denitrification. To use this layout reduced the operating costs by some 10% as compared with conventional processing only comprising downstream denitrification. Operating costs were respectively estimated at 37 and 34 €/1,000 m3 for downstream denitrification and combining upstream and downstream denitrification layouts.

A summary of fifteen years of experience of the design, operation and performance several Venezuelan municipal wastewater treatment systems to serve a population of 5 million is presented. Technical and institutional problems which occurred during construction and operation are described and some of the solutions are presented. It was found that the most simple systems were the most effective and that it was important to develop solutions appropriate to local needs and avoid the technological dependance on imported spare parts.
