A system is disclosed for controlling the amount of treatment composition, e.g., cationic coagulant, to be introduced into an aqueous medium, e.g., a laundry waste water, having a content of non-solid fats, oils and/or grease (FOG) which is to be reduced. This system comprises a detector adapted to determine the electric charge value of a material comprising the aqueous medium having a FOG which is to be reduced and to provide a signal indicative of this electric charge value and an automatic processor provided with a relationship of the amount of treatment composition to be introduced into the aqueous medium to reduce the FOG of the aqueous medium to a given level as a function of the signal, and adapted to receive the signal and to provide a control signal to a source of treatment composition to control the amount of treatment composition introduced from the source of treatment composition into the aqueous medium.

Water treatment to reduce fog levels controlled with streaming current

A system is disclosed for controlling the amount of treatment composition, e.g., cationic coagulant, to be introduced into an aqueous medium, e.g., a laundry waste water, having a content of fats, oils and/or grease (FOG) which is to be reduced. This system comprises a plurality of detectors each of which is adapted to determine a parameter, other than the FOG level, of a material comprising the components of the aqueous medium and to provide a determined signal indicative of the determined parameter; and an automatic processor provided with a relationship of the amount of treatment composition to be introduced into the aqueous medium to reduce the FOG of the aqueous medium to a given level as a function of the plurality of determined signals, and adapted to receive the plurality of determined signals and to provide a control signal to a source of treatment composition to control the amount of treatment composition introduced from the source of treatment composition into the aqueous medium.
