  • Geotextiles in Construction Dewatering

    Woven geotextiles work wonders in dewatering applications as wraps around well screens and sump pit screens. The textile can be sewn into sleeves or tubes to be slid over the well screen or sump pit framework. This technique allows the user to compensate for well screens with slots that are too large or for sump pit piping with large perforations. By adding the geotextile sleeves the user ...

  • Thermal hydrolysis, anaerobic digestion and dewatering of sewage sludge as a best first step in sludge strategy: full scale examples in large projects in the UK and strategic study including cost and carbon footprint.

    Abstract This paper shows that by using thermal hydrolysis process (THP) as a pre-treatment for anaerobic digestion (AD) it is possible to develop a step wise approach to sludge strategy that is cost effective and flexible. By generating a low volume of non odorous, well dewatered and safe digested cake it is possible to recycle sludge directly to agriculture or dry it for fuel use or ...

  • Development of the Sleeper Pit Lake

    The Sleeper open pit gold mine operated from the mid-1980s through the mid-1990s. Operations were mostly sub-water table and extensive dewatering was required to lower groundwater levels by 180 m. Dewatering flows peaked at 930 L/s, with most flow contributed from an alluvial aquifer. After completion of mining, the pit was rapidly filled with water pumped from the alluvial aquifer to reduce the ...

  • Dredging Technology – Underwater Excavation and Construction

    The presence of water is ussualy considered a nuisance in construction, particularly when excavating removing water is common practice. In some cases however, water can be a very useful tool that may simplify things greatly. With the “flooded excavation principle”, the construction site is flooded after the retaining walls have been installed (e.g. sheet pile). When the ...
