"It goes beyond just the technology -- at Perma-Fix we deliver turn-key solutions."

In spring 2020, Perma-Fix debuted Perma-Sort^℠, a new automated radiological characterization and segregation system for bulk materials. Drawing on our team of project managers, nuclear engineers, and certified health physicists (CHPs) with more than 50 years of soil sorting experience, Perma-Fix built a customized conveyor-based radiological assay system designed to provide 100% characterization of material efficiently and with industry-leading measurement quality. This innovative system offers management of end-point uncertainty with the characterization of both material exceeding the site acceptance criteria for transportation and disposal offsite and material meeting the site unrestricted release criteria.

How Perma-Sort Works:

Materials are loaded into a large feed hopper and then transported through the system with an electronically controlled conveyor survey belt. While on the survey belt, the material is analyzed and tracked. At the end of the survey belt, the material is transferred to a short reversing conveyor that spins in one direction for below criteria material and in the opposite direction for above criteria material. The reversing conveyor transfers materials to standard stacking conveyors which can then create piles of material or transfer directly to trucks or waste containers.

Supports a Broad Range of Contaminates:

• Fission Products
• NORM/TENORM
• Transuranics
• Heavy Metals
• Beryllium
• UXO/MEC

Perma-Sort Capabilities:

• Trailer mounted system for simple and rapid mobilization and setup
• Material output can be discharged into virtually any container size or managed with multiple takeaway conveyors
• Capable of processing > 200 tons of bulk materials per hour
• Industry leading radiological measurement quality
• Operating software supports multiple material profiles for varying bulk material types
• Automated reporting supports MARSSIM and FSS objectives as waste disposal objectives such as profiling and waste disposal
• Abundant guards, railings, remote e-stops, and keyed lock-outs ensure safety for system operators and near-by support staff
• Material is processed with minimal effluent and noise emissions

Leverage Our Extensive Experience with Elemental Mercury Disposition

Mercury of various forms have been widely used throughout the U.S. and internationally, and to date, more than 600,000 pounds of this radioactive waste co-contaminated with mercury have been processed by one of Perma-Fix's many treatment technologies. Perma-Fix has implemented treatment solutions based on available and patented technologies to address these problematic wastes.

Perma-Fix provides effective treatment of radioactive-contaminated elemental mercury via amalgamation, the required treatment method for these wastes. Perma-Fix employs a patented amalgamation process using proprietary reagents that meet the EPA technology treatment standard (AMLGM). This process treats elemental mercury waste to meet the requirement of AMLGM using chemical reagents that bind the mercury and render it non-leachable. Mercury treatment is provided in a dedicated area of the facilities, with its own air handling and filtration system, for treatment of large volume, mercury contaminated wastes (elemental) using a proprietary amalgamation and stabilization process.

Two of our four facilities, Perma-Fix of Florida and Diversified Scientific Services, are licensed and permitted to receive, handle and store mercury for up to one year. With over $50 million of investment in facilities and technologies, Perma-Fix offers the most comprehensive low-level radioactive waste (LLW) and mixed low-level radioactive waste (MLLW) treatment facilities available in the U.S. Our experience, capacity, and regulatory compliance history set us apart in the industry. We are continually investing in new technologies to offer the most current state-of-the-art treatment options in the market.

Acceptable Mercury Wastes

• Wastes with soluble mercury (less than 260 ppm)
• Soils with high mercury levels (greater than 260 ppm)
• Wastes (non-soils) with high mercury levels (greater than 260 ppm)
• Elemental mercury
