Abstract
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.
