This slide presentation outlines background information on hollow-fiber membrane biofilm reactor (MBfR) that includes: perchlorate reduced to harmless Cl- ion and nitrateharmless N<sub>2M</sub> gas;H<sub>2</sub> gas supplied by diffusion through the walls ofspecial "bubbleless" hollow-fiber membranes;H<sub>2</sub> is an electron-donor substrate (i.e., food) formicroorganisms that reduce (i.e., "breathe") almost anyoxidized solute, especially including perchlorate andnitrate; and,the membrane wall is the meeting point for what themicroorganism use to live, it is the natural place for abiofilm to form. Includes tables, figures.
