Heavy Metals Treatment Products

Free Flow Chemistry

Free Flow Technologies, Ltd. offers a variety of reagent blends that are specially developed to reduce the mobility of heavy metals in contaminated materials. The Free Flow chemistry has been utilized throughout the United States and has proved to be effective on all 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.

The Free Flow blends have been approved for use in remediation projects directed by the U.S. Army Corps of Engineers, USEPA, DOD, U.S. Navy, U.S. Air Force, National Park Service and various state and local agencies.

Free Flow 100®

Free Flow 100® (FF-100®) reagent is a nonreversible chemical fixation chemistry for RCRA heavy metals stabilization in contaminated waste materials and soils and is utilized throughout the United States in fixed-based applications.

Typical Applications
