Abstract:
1. A solid-liquid separator system comprising: an activated carbon adder configured to add activated carbon to raw water upstream of a flocculation sedimentation unit, to adsorb suspended matter contained in raw water; a liquid cyclone adapted to separate activated carbon with suspended matter adsorbed thereon, from raw water containing activated carbon; an inflow line configured for connection thereof with the liquid cyclone to cause raw water containing activated carbon before flocculating sedimentation to flow into the liquid cyclone and swirl therein; an activated carbon discharge line configured to discharge activated carbon spun down out of raw water containing activated carbon in the liquid cyclone, from the liquid cyclone; a pretreated water discharge line configured to discharge raw water having got rid of activated carbon as pretreated water from the liquid cyclone; a sensor adapted to detect a quantity of activated carbon contained in raw water in the liquid cyclone; and a controller adapted to control a valve installed on the activated carbon discharge line and configured to adjust a discharge rate of activated carbon of the activated carbon discharge line in accordance with a detection result of the sensor.
