Aclosed-loop ecosystem is being designed for long-duration space missions. within that system, a biofilter will utilize bacteria to convert nitrogen from fish waste (nh3) into a form usable by plants ( the biofilter consists of a cylinder filled with spherical particles (like a jar full of marbles) upon which the bacteria attach, and water then flows through the cylinder past the bacteria. the water flow rate through the system is 25 g h20 / s, and the inlet concentration of nh3in the water is 9x10-6g nh3/ g h20. if the bacteria in the filter are removing nh3at a rate of 41x10-6(g nh3)/s, what is the concentration of nh3in the outlet water, in g nh3/ g h20?
