Heavy Metal Removal Lab Reports
MetFloc One-Step Process of Metal Removal from Wastewater

After & before treatment of metal-laden wastewater.

Analytical laboratory results of wastewater samples treated with MetFloc chemicals. The results are from independent EPA-certified labs using some of the most sensitive analytical techniques (inductive-coupled plasma (ICP) and graphite furnace techniques).
