Heavy Metals Treatment Products

Free Flow Technologies, Ltd. offers a variety of reagent blends that are specially developed to reduce the mobility of heavy metals in contaminated materials. Utilizing reactive anions, our reagents fixate metals by converting them into insoluble minerals. Special additives further bind and lock the metals within an oxide lattice structure that is stable across a variety of adverse chemical conditions.

The Free Flow chemistry has been utilized throughout the United States and has proved to be effective on RCRA metals. The combined additives form a blend that prevents leaching in all types of environments. The blends pass the SPLP, TCLP and MEP, which is the EPA approved method for determining the long term stability of treated waste.They have been approved for use in remediation projects directed by the U.S. Army Corps of Engineers, USEPA, DOD, U.S. Navy, and various state agencies.

SDS Information

Free Flow 100®

Free Flow 100® (FF-100®) reagent is utilized throughout the United States in both fixed-based applications and remediation projects for the stabilization of heavy metals in contaminated waste materials and soils.

FF-100® is effective on a variety of RCRA metals and most frequently used to stabilize lead, cadmium, barium and chromium. The chemistry is capable of achieving results below the universal treatment standard and produces a stabilized material with long-term stabilization characteristics.

Free Flow 200®

Free Flow 200® (FF-200®) reagent has proven to be an effective and economical alternative to traditional blends for lead stabilization in soils and sludges. FF-200® is easy to handle in the field and provides effective non-reversing fixation of the lead at low dosages.

Free Flow 300®

The chemistry is robust and fast acting to form insoluble salts with RCRA metals at low dosages and ensures protection from future liability in onsite and commercial landfills.


  • Lower Dosages
  • Cost Savings

When compared to the competition, this chemistry sells at half the cost and ensures a lower dosage than other chemistries.
