Beschreibung
Zusammenfassung:	This invention relates to an improved hydraulic system for conveying a liquid-solids slurry over relatively long distances without reducing the consistency of the slurry. More specifically, this invention relates to an improved hydraulic system that eliminates or substantially reduces the number of booster or auxiliary pumping units needed to maintain appropriate flow conditions when conveying a liquid-solids slurry over relatively long distances. This is brought about by selectively adding a surfactant to the slurry being conveyed in response to a deposition indicator that senses the rate of settlement of solids on the lower portion of the conduit conveying the slurry.
