A ferrous foundry located in the deep south has been using EnviroBlend 93 HR to treat lead and cadmium-contaminated baghouse filter bags since 2009. EnviroBlend is added in-line as part of their process by using a duct injection method at a low dosage rate which renders their baghouse dust non-hazardous according to the EPA Toxicity Characteristic Leaching Procedure (TCLP). The foundry produces DI pipe joints and couplings.
