The disclosure relates to methods for operating a pasteurizing device for pasteurizing foods filled into sealed containers. The foods are treated in treatment zones by applying a tempered, aqueous treatment liquid to an exterior of the containers. The treatment liquid is re-supplied to at least one treatment zone for reuse via circulation circuit pipes of a circulation circuit. At least one actual value of a concentration of at least one chemical substance contained in the treatment liquid and/or of at least one process chemical added and/or of at least one internal standard added is detected by means of at least one concentration measurement sensor at at least one measurement point. A concentration, in the treatment liquid, of the at least one contained chemical substance and/or of the at least one process chemical added is manipulated on the basis of a detected actual value.

A drain box having a housing, a splash containment therein with a lower portion within a housing drain aperture, and a discharge conduit having a lower portion positioned within the splash containment in position above the drain aperture and extending upward through splash containment aperture, and an upper portion extending upward through a housing upper aperture and terminating above the housing upper portion for connection to an appliance discharge conduit. The conduit being attached to the housing to prevent a lower discharge conduit end from moving downward toward the drain aperture to less than a predetermined minimum distance above the housing drain aperture.

Systems and methods for applying a chemical treatment solution to a process stream in an industrial processing system while the system is online. The method includes measuring a real-time pH of the process stream, determining a dosage of the chemical treatment solution based on a relationship between the dosage and a scale saturation parameter that is calculated based on the real-time pH of the process stream, and controlling application of the chemical treatment solution to the process stream based on the determined dosage.
