Abstract: Studies of an existing system showed air injection into a force main was an effective, economical, and reliable measure for controlling sulfides generations. Additional benefits included some degree of BOD reduction and removal of friction-producing bacterial filiments. Air at the force main outlet was not odorous, and contained only trace amounts of hydrogen sulfide. Generation of sulfides returned to normal levels a few days after aeration ceased. Analytical techniques used may apply elsewhere. The design rationale may be of value in other installations in which general conditions are similar.
