Abstract

See full text

Industrial methods which utilize microwave-based sensors to detect in real-time the total solids content of aqueous solid colloidal dispersions such as oil sands tailings streams are provided. Optionally, these microwave-based sensors may be utilized in combination with automatic cleaning systems or filters, which prevent sensor fouling and allow for extended sensor use without manual cleaning. The output signals from the microwave sensor are used to adjust desired process parameters, e.g., the dosage of chemical additives and/or to maintain total solids within specified limits.
