Abstract
Systems for producing performic acid and methods for producing performic acid. The systems may include two or more reactor units, two or more servient programmable logic controllers, a control panel, and a master programmable logic controller. The system may modify the production of performic acid in at least one of the two or more reactor units upon and/or after the occurrence of a disruptive event in order to maintain a desired level of performic acid production and/or a desired level of disinfection.
