Microbiologically enhanced GCW

By means of different techniques oxygen, gas mixtures but also nutrient solutions can be added to the GCW circulation water. Thus, more oxygen-rich and contaminant-reduced groundwater circulates through the aquifer and stimulates microbiological degradation respectively creates better bio-availability. Metabolites impeding the growth of autochthonic microorganisms or the CO2 produced by the biological decomposition can be transported to the well with the groundwater and can be selectively removed there.
