Abstract

The present invention concerns a method of estimating and optionally controlling the microbiological state in a process stream of an industrial process by measuring the concentration of dissolved oxygen or the rH value, or both, in said stream, the method including continuous or periodic sampling and online measurement. The invention also concerns a device suitable for use in implementing said method.
