Groundwater Remediation
Our range of services in the area of groundwater remediation encompasses planning of groundwater remediation installations, their construction, operation and maintenance, as well as the production of required infrastructure (for supply and discharge of groundwater etc.). Through the use of modern automated technology, project visualisation and remote monitoring, we have installations which are low-maintenance and offer increased operational reliability/process stabilisation and availability.
Our experience over many years in remediation plant construction and the modular nature of our installations allow us to offer an ecologically and economically optimal process for every situation.

ARGUS GmbH offers the following methods for clean-up of contaminated groundwater:
•Sedimentation
•Light-NAPL Separator
•Gravel filtration
•Packed-bed-/Submerse-biology
•Desorption Columns
•Adsorption Filters (activated-carbon, adsorbent resins)
•Ion Exchanger
•Sedimentation•Light-NAPL Separator•Gravel filtration•Packed-bed-/Submerse-biology•Desorption Columns•Adsorption Filters (activated-carbon, adsorbent resins)•Ion ExchangerNext to the “classic“ processes for groundwater remediation, e.g. adsorption (activated-carbon filtration) or stripping, we also favour microbiological processes and combinations of microbiological and physico-chemical clean- up steps.
Microbiological processes suit the following types of groundwater contamination:
•Benzin, Toluene, Ethylbenzene, Xylene (BTEX)
•Mineral oil Hydrocarbons (e.g. Diesel, Heating oil, Transformator oil etc..)
•Low condensed Polycyclic Aromatic Hydrocarbons (PAH)
•Surfactants
•Phenols (in particular Alkylphenols)
•Semi-Volatile Halogenated Hydrocarbons (SVHH) – limited capability

In this process, the contaminants accumulate and become concentrated on the adsorbent. The loaded adsorption material is incorporated into special installations as a type of regeneration/recovery.
In special cases, for example heavy metal or cyanide contamination, we incorporate ion exchangers. In multi-stage installations, ion exchangers are able to regenerate during the operation of the system.
For semi-volatile contaminants such as BTEX or SVHH, we also use stripping installations (desorption columns, sieve tray tower). In this process, contaminants are stripped from the groundwater through injection of air against the flow of water. The contaminated exhaust air is then subsequently cleaned using suitable techniques (air activated-carbon, biofilter, CatOx).
Stripping of semi-volatile contaminants can also be performed directly in the groundwater aquifer (Airsparging). Air is injected into the aquifer through a system of aerators. The semi-volatile contaminants are then driven out of the saturated zone and are subsequently extracted through soil vapour. The injected air also stimulates the biodegradation of contaminants by microorganisms.
This process suits permeable and homogenous soil types in particular. The process therefore has advantages on built and developed sites, as the structural environment generally remains unimpacted during installation and operation.

For microbiological clean-up of contaminated groundwater, we install submersed or “Packed-bed” reactors. As microorganisms within the submersed reactor are mobilised and go into suspension, they become re-attached to a special growth material in the Packed-bed reactor. A greater space time yield can be achieved in this effect. The dwell time is shortened. As a precaution, we attach an activated-carbon filter downstream from the biological stage.
As clean-up performance in the microbiological stage is typically quite high (dependent on contaminant type and concentration before remediation), this allows for considerable savings in activated-carbon usage and energy. This makes microbiological remediation a unique resource saving and cost-effective process.
