Industries and municipalities are under increasing pressure from water quality regulators to clean up dissolved metals, nitrate and other inorganic contaminants. Waste streams and water bodies with even trace amounts of certain inorganic compounds are attracting more and more attention of the public and of government agencies. Conventional precipitation, ion exchange and absorption methods for metals removal often have difficulty in consistently treating certain compounds to the low levels being enforced by state and federal regulators. That is why environmental and water resource managers are looking for better, more cost-effective alternatives to conventional water treatment for metals and other inorganics. The GE ABMet system is built around an advanced biological wastewater treatment
process that uses naturally occurring non-toxic, non-pathogenic microbes in
specially developed mixtures, which reduce and precipitate target compounds
from solution, or convert target compounds into their insoluble chemical components. The ABMet Process Biological Reduction and Precipitation Unlike other biological methods which pay passive, little or no attention to the types of microbes employed, the ABMet® system relies on specific and proprietary microbial mixtures to perform specific treatment activity. Not all microbes, even of the same species, will perform the same in all types of water chemistries. More than a decade of research was spent in isolating the most effective strains of useful microbes to use in a range of ABMet® system configurations that address differing treatment goals in differing types of water. Optimized ABMet® cultures are established as robust biofilms inside a bioreactor or set of bioreactors designed into existing water treatment trains or as stand alone units. ABMet® nutrients are automatically delivered to the system on an optimized schedule to maximize only targeted microbial activity and to minimize costs. Target contaminants are precipitated as elements (i.e. elemental selenium) or sulfides (i.e. arsenic sulfide), depending on the ABMet® culture used, or are destroyed or degraded as in the case of compounds such as nitrate. The results are a highly effective and efficient biological system, one that
remains stable over the long-term. ABMet® systems can be controlled precisely
and consistently to achieve targeted contaminant removal to target levels. ABMet Features and Benefits Saves Money
