Zusammenfassung:	An apparatus for generating and storing in a tank 22 a flowable slush 2 of frozen particles usable inter alia in ice pigging comprises a control system 100 which is arranged to monitor an operating parameter OP of an agitator 23 in the storage tank. The control system initiates a slush comminution and separation or dewatering cycle when a control parameter CP based on the operating parameter OP reaches a threshold value CPt. The control parameter may represent a cumulative energy input to the storage tank 22. Comminution may be performed prior to separation, with the treatment cycle being terminated when a sensed rheometric parameter RP of the slush circulating in the treatment flowpath reaches a target value RPt.
