Applicability of ground source heat pumps as a bioremediation-enhancing technology for monoaromatic hydrocarbon contaminants

Ground-source (geothermal) Heat Pumps

Current status of ground source heat pumps in Europe

Geothermal Heat Pumps, or Ground Source Heat Pumps (GSHP), are systems combining a heat pump with a ground heat exchanger (closed loop systems), or fed by ground water from a well (open loop systems). They use the earth as a heat source when operating in heating mode, with a fluid (usually water or a water-antifreeze-mixture) as the media transferring the heat from the earth to the evaporator o...

Bioremediation of petroleum hydrocarbon contaminants in marine habitats.

Bioremediation is being increasingly seen as an effective, environmentally benign treatment for shorelines contaminated as a result of marine oil spills. Despite a relatively long history of research on oil-spill bioremediation, it remains an essentially empirical technology and many of the factors that control bioremediation have yet to be adequately understood. Nutrient amendment is a widely ...

Heat pumps as a source o f heat energy for desalination o f seawater

Thermal desalination plants consume large quantifies of heat energy for seawater evaporation. In condensing water vapor procured in evaporators and cooling distillate, a major part of heat energy is lost in the environment. Heat energy in processes of condensation and evaporation in desalination of seawater is quantitatively equal but these processes take place under different temperatures. Dif...

State-of-the-art Survey of Existing Knowledge for the Design of Ground-source Heat Pumps

The objectives of the program reported here were to gather design and performance information on historical and current ground-coil heat-pump systems, to assess the adequacy of available design methods, and to define near-future R&D needs to promote the use of this technology. The project was generally separated into two parts: (1) a review of the North American technology conducted by Battelle...
