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).
