Remediation Trends, Treatability Study Services

Bench-Scale Treatability Testing

AprilNews Photo1Treatability studies provide a low cost evaluation for the development of site- specific chemistries for remediation of heavy metals and organics. Well-designed treatability studies can identify better reagent choices at lower doses that result in cost savings and reduced risk of treatment failure.  With a treatability study, chemistries are designed for specific site conditions, and allow for evaluating alternate treatment scenarios and land use options.

Treatability Study Approach

  •  Assess project goals
    • Site-specific study design
    • Sampling design and support
  • Evaluate remedial alternatives
  • Measure long term stability

In-Field Confirmation Testing

Testing services comparable to treatability tests can also be used during the full-scale implementation of a remedy in order to provide “real time” confirmation of success:

  • Saving time and money, and potentially
  • Optimizing reagent doses, reducing treatment costs

Bench and Field Laboratory Services

The ReSolution Partners treatability study laboratory can provide batch and column studies for metals stabilization, total oxidant demand determination, and organics oxidation.  Our experienced staff develop innovative, site-specific test protocols and chemistries designed to meet project goals.  Screening indicators are often determined during bench-scale studies that can be measured during full-scale implementation to evaluate treatment performance.
