Biofilter For Nitrate Reduction


Project Motivation: In a time of severe drought throughout the Western U.S., it is essential to efficiently utilize all water resources. Using preexisting microorganisms to remove the common contaminant nitrate from impacted water would make one more valuable resource available to the public.


Project Description: Tembo Inc. and BKT Co. Ltd shall provide Tucson Metro Water District in Arizona with a biological filtration system to reduce nitrate contamination in

Its irrigation groundwater well so that it may be used to produce drinking water. This design optimizes cost and efficiency, while providing clean water for City of Tucson residents.
