Treatability Study Services

PFF Treatability Laboratory personnel The Perma-Fix of Florida facility in Gainesville, Florida houses a state-of-the-art mixed waste analytical chemistry laboratory which conducts treatability studies to enhance or develop treatment processes for specialty wastes. In addition, since the laboratory is located within a licensed and permitted operating waste treatment facility which treats a variety of characteristic and listed waste soils, liquids, sludge, and debris to meet Land Disposal Restrictions (LDR) standards and/or other disposal objectives, personnel are available for consulting on scale-up issues that may be addressed during bench testing.

Features of Treatability Testing Services
Perma-Fix Environmental Services, Inc. has demonstrated capability to develop and commercialize compliant and cost-effective treatment processes for unique and problematic wastes through treatability studies.
  • Fully equipped licensed and permitted analytical laboratory;
  • Providing treatability studies to enhance or develop treatment processes for specialty wastes;
  • Performing bench-scale optimization tests;
  • Fully qualified personnel can assist with scaling-up of process methods developed; and
  • Use of either non-radioactive waste surrogate or real waste samples based upon client requirements.

The Treatability Laboratory personnel can perform bench-scale optimization tests using either non-radioactive waste surrogate or real waste samples based upon client requirements. The facility has the necessary engineering (fume hoods, no floor drains, monitoring instruments, etc.) and administrative (standard operating procedures, routine inspections and surveys, safety support staff, etc.) controls to facilitate performance of the work in a safe and effective manner.

The Technical Services staff have decades of combined experience in developing and optimizing waste treatment processes and have participated in the successful development of bench-scale and full-scale treatment processes for many waste streams as identified in the Waste Treatability Studies table.
