The required water protection measurement was performed in four working steps according to the planning of the designing office Misera in Freiburg: A 10cm thick sand layer was installed over the prepared subgrade A needlepunched geosynthetic clay liner (GCL) ...
As part of the shutting down of the nuclear power station in Chernobyl, a surface respository for weak to medium radio-active waste is being constructed around 30 km away from the power plant premises. The total building project JCSRM-Industrial Complexe for Solid Rodwaster Management) is sponsored by the EU and RWE Nukem GmbH, general contractors for these measures, commissioned NAUE GmbH & ...
Generating power with natural gas engines in large commercial buildings, while controlling emissions and noise from the engines requires a unique catalytic solution. Johnson Matthey’s new QXC model 3-Way converter silencer was chosen for the task. This design contains a unique catalyst element sealing system that insures against pollutant bypass. Background Equity Offices had a need to ...
Umbrella lining with Carbfol Today's modern traffic tunnels are increasingly being planned with a projected functionality for over 100 years – despite difficult geological and engineering conditions. The overriding objective of tunnel construction is the protection against the effects of groundwater and penetrating water. The local conditions at the highway tunnel construction site on the ...
We are presenting the use of BÜCHI's Extraction Unit B-811 for isolating polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) from solid environmental samples (soil, grass) under standard conditions and by means of hot extraction. The extracts received will be further processed by means of an internationally recognized method and analyzed with high-resolution GC/MS in the single-ion ...
AVA was recently able to present a newly developed horizontal reactor for laboratory operation. After comprehensive tests at the technology centre, a special machine type was developed for the purpose of drying powdery raw materials for filter elements. The high-tech filter elements are manufactured as end-products for usage in diverse industrial applications. The challenge in the development ...
Opened in 1987, the municipal landfill Ämmässuo in Finland extends over 50 ha, making it one of the largest in all of Scandinavia. Two test fields were set up to find a suitable solution for the surface sealing system and future slope reinforcement The structure of these fields consists of a mineral gas-drain layer, a mineral sealing layer, a geosynthetic clay liner, a protection ...
The largest main collector within the jurisdiction of the Public Utility Company Essen has a nominal diameter of DN 3800. This main collectortown centre presented damages thatwere in need of redevelopment. After a thorough inspection, 33 leaky joints were selected for this pilot project and the company SMG Bautenschutztechnik fur Hoch und Tiefbau GmbH received the order. Project description The ...
A high volume jet water pump has been working on board of a sand dredger, belonging to the Dutch company De Vries & van de Wiel, since May 2010. This big 20" pump has worked flawlessly without significant maintenance since the first commissioning. After more than 10,000 hours of reliable service, the drive - a powerful V12 diesel engine - needed a complete overhaul. During this work BBA ...

Provide anti-adhesion, anti-scratch, anti-fouling and anti-friction effects, while providing a smooth and ...
As part of the implementation of a barcode-based system to track Radioactive Sealed Sources (RSS) in Egypt, the Regulatory Authority Information System Personal Digital Assistant (RAIS PDA) application was developed to extend the functionality of the International Atomic Energy Agency's (IAEA's) RAIS database by allowing users to download RSS data from the database to a portable PDA equipped with ...
The project DeWaLoP, led by Vienna Water, aims to develop a robot that is able to apply a sealing system to repair the joint sockets of pressure operating water pipes measuring about 1 m in diameter. To do this, a modification of the sealing material for inner surface application will be developed and a complex robot system will be designed to perform various tasks, such as inspecting, cleaning ...
Geosythetic lining works include the installation of a 1,825m2 of 1.5mm smooth HDPE liner over the concrete roof of one existing and one new reservoir. Works included Fusion and extrusion welding techniques Sealing of HDPE liner to vertical concrete surface of 6nr. access hatches using a stainless steel battening system Fabrication and sealing of 16 nr. pipe boots around cylindrical ...
When it comes to drill cuttings and contaminated soils treatment, numerous technologies are available on the market. For heavy oily wastes, especially OBM cuttings and sludges, only thermal processes have proved to be effective. For the last decade, few technologies have been competing for the latter oily wastes. In particular, traditional indirect fired rotary kilns and VacuDry® vacuum ...
PROBLEM A leading producer of bottled mineral water was experiencing problems using a conventional glass bead carbonator for dispersing and dissolving carbon dioxide gas in water. Consistent gas bubble sizes were impossible to achieve without frequent maintenance and lost production. A further problem with the conventional equipment, which was designed without any particular attention to ...
Abstract This paper describes the advanced in-service tank inspection methods available for use in the inspection of aboveground storage tanks (AST) in the petroleum and petrochemical industry. ASTs are subject to several federal and state regulations requiring tank owners to perform tank floor/bottom integrity, seals system, and deck fittings inspections on a routine basis. The conventional ...
