PATENT-BASED PCB TECHNOLOGY / SITE-SPECIFIC VALIDATION

Soil remediation for complex contamination

From investigation and treatability testing to in-situ treatment, adsorption and groundwater control.

MEISTER plans each project around the contaminant profile, soil and groundwater conditions, land use, regulatory criteria and verification method. The technology disclosed in international patent publication WO2011074120A1 provides a technical basis for evaluating persistent organochlorine contamination, including dioxins and PCBs.

01

Soil remediation for complex contamination

Integrated project design

Investigation, bench testing, treatment design, construction and verification are connected in one project plan.

Treatment selected by contaminant

Decomposition, immobilization, adsorption, separation and controlled disposal are evaluated according to the target substance.

In-situ and groundwater control

Solutions can be designed to limit excavation while managing contaminant migration and groundwater.

02 / FOCUS

Vietnam dioxin remediation: a verification-led proposal

PCBs, PCDDs and PCDFs are structurally related persistent chlorinated compounds; some PCBs are classified as dioxin-like PCBs. Based on our patented PCB technology, we propose staged treatability testing for dioxin-contaminated soil, followed by third-party analysis and a site-specific process design.

  1. 01Review historical data and sampling plan
  2. 02Characterize congeners, concentration and soil matrix
  3. 03Laboratory treatability test
  4. 04Third-party analysis of soil, water and emissions
  5. 05Pilot-scale verification
  6. 06Full-scale design and regulatory review
03

Information required for a proposal

01Country, site and project authority

02Target compounds and analytical reports

03Contaminated area, depth and estimated volume

04Soil type, moisture and groundwater conditions

05Required regulatory criteria

06Available utilities, area and schedule

Structural similarity and PCB treatment experience do not by themselves prove dioxin treatment performance. No removal rate, completion period, safety or cost is guaranteed before representative testing and regulatory review.
