Fig. 10From: Pilot-scale electro-kinetic remediation of lead polluted field sediments: model designation, numerical simulation, and feasibility evaluationEnergy consumption (a) and cost analysis (b) of the treated unit area under the optimal EPI-EKR (0.5 V/cm, 12 h of EPI duration). The relative cost-effective point referred to the moment that sharp increase of the energy cost was required to remove 1 mg Pb in sedimentsBack to article page
