Washing of contaminated soils

Reaction of alkaline substitution of toxic metals in EDTA chelate and alkaline precipitation of released toxic metals, coupled to acidic precipitation of EDTA was used to develop a novel, soil-sustainable method for remediation of toxic metals contaminated soils. Technology recycles EDTA and all process solution in a closed process loop. No wastewaters are generated.

Soil and sediment remediation

Novel reaction of alkaline substitution of toxic metals in EDTA chelate and alkaline precipitation and adsorption of released toxic metals on polysaccharides, coupled to acidic precipitation of EDTA was used to develop a novel, soil-sustainable method for remediation of toxic metals contaminated soils. Patent application strongly enhances technology performance and reduces the process installation cost with regard to technology developed in the previous patent.

Combined EDTA soil washing and stabilization of residual toxic metals

EDTA soil washing cannot remove toxic metals from soil quantitatively. Toxic metals which remain in soil after soil washing were immobilized with phosphates to further reduce their mobility an bio-availability.
