Vertical-flow constructed wetlands as an emerging solution for faecal sludge dewatering in developing countries
Yard-scale experiments aiming at assessing the suitability of vertical-flow constructed wetlands to dewater faecal sludge (FS) were conducted in Yaoundé (Cameroon). During 6 months, beds vegetated either with Cyperus papyrus L. or Echinochloa pyramidalis (Lam.) Hitchc. & Chase were fed under constant solids loading rates (SLR) of 100, 200 and 300 kg TS (total solids) m−2/year. Physicochemical ...

Dewatering Crews Keep the Alameda Corridor Dry and Open for Business
Griffin installed a multitude of deep wells along the alignment of the proposed railway to allow for construction. The discharge from the wells was pumped via large diameter high density polyethylene pipe (HDPE) to a below grade mixing vault, where a neutralizing agent was introduced to the groundwater as the quality of the groundwater was not allowed to discharge to the designated receiving ...

Temporary Construction Dewatering Solutions
Mention “dewatering” to anyone outside of the underground construction trade, and typically, with a blank stare, they’ll ask what is D-watering? Mention dewatering to anyone in the underground construction trade, and they’ll likely state that it is one of the most important phases in the project, as a well designed and installed dewatering system will allow them to ...

Glass Recycling Facility Wastewater Treatment Case Study
Recycling Wastewater Treatment Success Stories Glass Recycling Facility Wastewater Treatment A glass recycling facility needed a means to increase the size of their settled solids so they could be dewatered in their filter press. The fine solids caused carry through of the press (cloudy filtrate) and did not dewater well. The samples tested were from the initial ...

Numerical Evaluation of Effectiveness of Drainwells in Dewatering Overburden at Surface Coal Mines
Abstract: Typical sedimentary sequences overlying coal seams consist of interbedded sandstones, siltstones, shales, and rider coal seams. In many surface coal mine settings, these sediments are saturated; and prior dewatering of them is necessary for effective and economic mining, including the stacking of saturated spoils. Such sedimentary sections usually have a very low vertical hydraulic ...

How portable cofferdams can be used for shoreline restoration
We have a large number of lakes and waterways in the United States, plus a lengthy coastline as well. That means a large expanse of shorelines, which in turn means a hefty need for construction in and around shoreline areas. If you commonly work in areas involving shoreline restoration, then you will want to choose the best methods of getting the job done successfully. Portable Cofferdams Can ...

Numerical simulation of drainage scenarios for lowering groundwater rise due to construction of a new barrage on the Nile River
The government of Egypt constructed a New Naga Hammadi Barrage (NNHB) 3.6 km downstream of the Old Naga Hammadi Barrage (ONHB). Upon construction, the water level raised by about 0.5 and 4 m upstream and within the river reach between ONHB and NNHB respectively. In this paper, a two–layer groundwater model was built using MicroFEM to study the groundwater rising problem. The model was used to ...

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 ...
