GERME S.A.

BIOLOGICAL TREATMENT OF GROUND WATER

Jacqueline GIALLO CEO j.giallo@germesa.fr GERME S.A. – Marseille FRANCE Malta Water Week, March 2015

GERME S.A. environmental expertise

Since 1979 GERME is involved in environment protection, and develops biological products and processes for air, soils and water quality improvement. Among others its expertise is related to:

• Drinking water treatment
• Waste water treatment
• Lakes, ground water or other fresh water reservoirs decontamination or quality

improvement

• Water resources management and water saving technology
• Soils

bio remediation (hydrocarbons, chlorinated compounds, toxic metals,…removal)

• Air depollution
• Agro-food or industrial waste recovery

GERME S.A. activities

GERME activities diversify in R&D Services and Production.

GERME methodology consists of:

• Feasibility study,
• On-site pilot plant development,
• Assistance in setting up the water treatment unit,
• Needed biological consumables supply,
• Process monitoring.

Biological treatment principle

Biotreatment consists of using specific microorganisms able to degrade or remove targeted pollutants. Microorganisms are screened in our laboratory from natural ecosystems, they are not pathogenic according european directive 2000/54/CE and non GMO. GERME offers two alternatives for groundwater biotreatment:

• in situ technology
• ex situ technology

In situ biotreatment of ground water polluted by chlorinated compounds

POLLUTING COMPOUNDS

Vinyl Chloride Monomer Ethyl chloride Dichloroethylene Trans-12-Dichloroethylene Dichloro-11-ethane Cis-12-Dichloroethylene Chloroform 12-Dichloroethane 111-Trichloroethane Carbone tetrachloride 12-Dichloropropane Trichloroethylene 112-Trichloroethane Perchloroethylene Tetrachloroethane Pentachloroethane

In situ biotreatment: mean annual chlorinated compounds of the ground water

Ex situ organic compounds biodegradation pilot plant

The plant specificity is mainly supported by selected micro-organisms for targeted pollutants removal
