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).
