A probe is conveniently positioned in a flowing aqueous medium. The probe is formed by two electrodes of notable difference in nobility connected by an electric resistance high enough to ensure that the voltage difference between its terminals is sufficiently great to permit accurate and simultaneous determinations of the growth of biofouling and the chlorine concentration by measuring the potential difference variations between the terminals.

[ The claimed invention is:] [1.] A system for monitoring biocide treatment of an aqueous medium, the system comprising:a probe comprising a metal working electrode and a sacrificial electrode of a metal less noble than said metal working electrode, said metal working electrode and said sacrificial electrode being exposed in a flowing aqueous medium receiving a biocide treatment;an electrical resistance connecting said metal working electrode and said sacrificial electrode, said electrical resistance ensuring a passively generated difference between said metal working electrode and said sacrificial electrode of at least 0.4 volts which ensures simultaneous and continuous determination of a biofilm growth on said probe and a chlorine concentration of the flowing aqueous medium;a processor connected to said probe and acquiring data therefrom, said processor displaying the data and directing start, modification and completion of the biocide treatment based on the data; andan auxiliary probe having two electrodes of different nobility metals that are in the flowing aqueous medium and connected by a further electrical resistance so that said auxiliary probe ensures determination of total oxidant concentration of the flowing aqueous medium, and a device for keeping said two electrodes of said auxiliary probe free of a biofilm.
