Exposed Geomembrane System at Großer Mühldorfer See Dam
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (6/2016)
Großer Mühldorfer See, a gravity dam owned by Verbund Hydro Power GmbH, will be part of Reisseck II pumped storage plant. The dam, 46.50 m high, has upstream prefabricated concrete slabs sealed with bituminous material and Kemperol strips requiring repeated repairs. A geomembrane system was installed to water tighten the dam and avoid maintenance. Among the challenges, the remote site location, the conditions of the facing and of the plinth, and the difficult climate. The article describes how design addressed such challenges and how installation was carried out to meet the objectives and deadlines.

Modernisation and Enlargement of the Drinking Water Plant Irsch-Treves - The second largest ultra filtration plant in Germany under construction
© DIV Deutscher Industrieverlag GmbH (9/2011)
The modernisation and enlargement of the second largest drinking water treatment plant (WTP) in Germany with the integration of an ultra-fi ltration stage began in February 2011, after more than a year of pilot tests. Following the current timetable the WTP in Irsch-Trier will be fully operational in summer 2013. The plant has a maximum capacity of 1600 m3/h and purifi es about 6 million m3 of drinking water per annum for the city of Treves and some surrounding communities. This paper gives a short description of the Riveris reservoir, the raw water and the existing WTP in Irsch-Treves. Furthermore, the reasons for upgrading the WTP, the targets for the new plant and the results of the pilot project are outlined. The bulk of the paper will however, be dedicated to the operational, design and constructional details of the new plant.

Design and Operation of an Ultrafiltration Plant for the Production of Drinking Water out of the River Scheldt
© DIV Deutscher Industrieverlag GmbH (9/2011)
In April 2009, the production capacity of the conventional drinking water treatment plant “de Gavers” in Harelbeke, Belgium, was extended from 25,000 to 32,000 m³/day by the construction of an ultrafi ltration unit. In this paper, the design of the ultrafi ltration unit is elaborated and the fi rst operational results with respect to membrane fouling, membrane integrity and effl uent quality are presented. With respect to membrane fouling, in-line coagulation applying a small dose of fl occulant was found to be necessary to keep membrane fouling under control. Membrane integrity testing demonstrated a log 4 removal for micro-organisms larger than 3 μm. Compared to the conventional coagulation-fi ltration plant the ultrafi ltration unit produces an effl uent with lower bacteria counts. Moreover, the turbidity of its effl uent is also substantially lower. However, the hydraulic yield of ultrafi ltration is considerably lower than that of the conventional treatment and it results in a higher waste water production.

Process Benchmarking in Drinking Waterworks in Germany
© DIV Deutscher Industrieverlag GmbH (8/2010)
The “water production process” summarizing resources management, water catchment and treatment is a key process in the water supply chain. During 2005 to 2008 a new bottom-up approach was developed and tested, allowing a detailed performance (cost, quality, sustainability) analysis on the process level and accounting for differing water resources, treatment schemes and assets. During subsequent projects some additional functions of the IWA performance indicator model for water supply (Alegre et al., 2006 [1]) have been supplemented on the process level, e.g. processes in water networks.
