Circolazione multipla

Monday 19 February 2007

The sphere of influence of GCW (Groundwater Circulation Well) depends on the distance of the two screen sections or, in case of a fully penetrating well, on the aquifer thickness. The larger the circulation cell is, the larger the travel time is for the circulation. For thick aquifers it may be beneficial to install several circulation cells, one upon another. This produces smaller circulation cells and shortens circulation flow time.

The IEG Groundwater Circualtion Well (IEG GCW) process is an in-situ system for the remediation of contaminated aquifers, especially those contaminated with volatile and semi-volatile hydrocarbons, using a combination of chemical, physical and biological processes. An IEG GCW process unit consists of a specially-adapted groundwater well, at least one submersible pump, a negative pressure stripping reactor located in a sub-surface vault, an above-ground mounted blower, and a waste air decontamination system (for example disposable filters or regenerative activated carbon filters).

Unita`di Strippaggio Integrata

Thursday 14 September 2006

Aree possibili di applicazione
L'UVB è un sistema in loco per il risanamento di falde acquifere contaminate, in special modo quelle contaminate di idrocarburi volatili e semivolatili o da metalli pesanti. Tale sistema utilizza una combinazione di processi chimici, fisici e biologici. L'UVB è un processo brevettato dalla IEG mbH, Reutlingen, Germania.

Estrazione Polimerica

Thursday 14 September 2006

The GCW-MPPE process is an in situ system for the remediation of groundwater contaminated with dissolved or dispersed aromatic, aliphatic, poly aromatic and halogenated hydrocarbons using a combination of a hydraulic controlled flushing/extraction system with a high efficient physical purification system based on macro porous polymer extraction.

Pozzo di Ricircolo (microbiologicamente assistito)

Thursday 14 September 2006

Due to the minimal environmental impact and low cost of implementation, biological remediation technologies have become increasingly popular during the last few years. In an ideal case, depending on the type of contaminants on the site, naturally occurring microorganisms degrade organic compounds to carbon dioxide and water. The rate of biodegradation is determined by the existing chemical and physical conditions. The goal of in-situ biological remediation technologies which IEG implements is to optimise the existing degradation potential.

Pozzo multifunzionale

Monday 25 September 2006

The Multi-Functional Well (IEG MFW) has been implemented for the remediation of subsurface contamination caused by hydrocarbon spills. Four different remediation processes can be operated within the same well. At optimal efficiency of each remediation process, successive treatment of the capillary fringes, the vadose zone, and the aquifer can be accomplished. Each treatment process requires only simple modifications of the well configuration. Removal of the contaminants is done primarily through in situ air stripping.

Pozzo di Ricircolo Reattivo

Thursday 14 September 2006

The Reactive Well Technology (GCW-R) significantly enhances the ability to combine a dynamic hydraulic flow system (GCW) with different reactive treatment areas under anaerobic conditions.

The specially designed remediation wells enable easy change to the reactive materials, such as controlled-release carbon plus zero-valent iron (ZVI) or other reduced metals, which is the subject of our EHC technology. One major difference between the GCW-R technology and a typical permeable reactive barrier (PRB) is

Pozzo di Lavaggio

Tuesday 12 September 2006

In the unsaturated zone, bioremediation is critically affected by the soil moisture content. For most natural biological degradation processes, the optimal water content is in range between 50% - 80%. With the Soil Circular Flushing Wella vertical multi-phase flow increases the saturation of water in the unsaturated zone. The remaining volatile hydrocarbons are either removed by in-situ stripping in the well, adsorbed on an optional activated carbon bed on top of the outer casing, or biodegraded in the well and unsaturated zone.

Barriera permeabile virtuale

Monday 25 September 2006

IEG-vPRB In-situ Virtual Permeable Reactive Barrier with Overlapped Circulation Cells.
When a GCW is situated within the body of a groundwater contamination plume, this creates effective hydraulic control across a large diameter spherical capture zone within the aquifer. The polluted upstream groundwater is systematically captured by the GCW and treated in the well and within the aquifer.
