Free Flow Technologies, Ltd.

Foundry Industry

Free Flow has been distributing treatment reagents to the foundry industry for 15 years and has overwhelming success in treating RCRA metals in all type of casting facilities. Free Flow has the ability with its high tech production plant to tailor a blend to meet the clients need and minimize the cost of the blend and the dosage rate. We are able to meet specific needs and not sell a standard blend to meet all needs. What works for one facility may be an overdose by a high percentage at another facility.

The chart below is an example of some types of foundry wastes encountered with varying degrees of metal concentrations. The dosages indicated are representative of the reagents ability to stabilize the waste in the lowest possible dosages.
