GE’s Advanced Biological Metals Removal Process (ABMet) technology is a patented biological water treatment system that uses naturally occurring microbes to reduce the amounts of selenium and other metals in discharge waters from coal mines and power plants. GE’s ABMet process involves running wastewater through a biologically active filter, which is “seeded” with naturally occurring microbes targeting selenium, typically difficult to remove from wastewater, and other potentially toxic metals.
