HOME COMPANY STRATEGY & VALUES OUR TECHNOLOGIES PROJECT APPROACH CASE STUDIES PRESS CONTACT ADVANTAGES & SCOPE OF APPLICATION ET-DSP™ is eaqually effective in both the VADOSE & SATURATED ZONES Wide range of organic contaminants: chlorinated solvents, hydrocarbons, BTEX, PAH, creosote... Ideally suited to extreme conditions Source of contamination: L&DNAPL Vadose and saturated zones All types of lithology: clay, sand, silt, peat... Creation of secondary porosity in impermeable lithology (clay) Heterogeneous lithology: interbedded layers – lenses Deep contamination (>20m) More than 95% of contaminant mass reduction (VOC) Rapid Treatment: 6 to 8 months duration Safety Performance: zero recorded accidents Scope of Application Temperature max 100 °C Average required energy 250 kWh/m3 All of organic contaminants : TPHs, PAH, HVOC, creosote,... All of geologies with electrical resistivity < 500 Ω.m Groundwater velocity < 0,3 m/j In Situ Thermal Improving mobility and extraction Advantages & Scope of application General description - 3D Movie Project approach Preliminary Study – Required Information In Situ Biological Advantages & Scope of application General description Why Euremtech?
