The presently disclosed embodiments utilize an ice separator vessel to trap ice particles in a non-homogeneous ice/fuel mixture flowing in a fuel system. A source of heat, such as heated fuel provided to the ice separator vessel, is used to melt at least a portion of the ice particles so that they do not enter the fuel system downstream of the ice separator vessel.

The problem to be solved by the present invention is to provide a method for producing an aqueous pigment dispersion that has certain dispersion stability with which the formation of coarse particles with time and the settling of a pigment and the like with time can be reduced and that can be used for producing an ink having excellent discharge stability. The present invention relates to a method for producing an aqueous pigment dispersion, the method including kneading a composition including a pigment including one or more materials selected from the group consisting of a violet pigment, a green pigment, and an orange pigment and a resin, the composition having a nonvolatile content of 50% by mass or more, under predetermined conditions and subsequently performing a centrifugation treatment.

An apparatus (1) and method for treating contaminated waste water (2). The apparatus comprises a heater (30), a feed apparatus (11, 12, 13, 14), for supplying contaminated waste water (2) to the heater (30) and a centrifuge (50, 60) downstream of the heater (30). A heat exchanger (20) is also provided which has a first channel (22) and a second channel (24). The first channel (22) is connected in a flow path extending between the feed apparatus (11, 12, 13, 14) and the centrifuge (50, 60); and a waste water outlet (9) from the main centrifuge (60) is fluidly coupled to an inlet of the second channel (24) of the heat exchanger (20).

Provided is a centrifuge that allows a user to easily determine whether running is normally completed or the running is not started. In the centrifuge having a setting screen 70A on which input of centrifugal running conditions and a centrifugal running state can be displayed, a control device performs centrifugal separation running of a rotor according to a set running time, a set rotation speed, and a set temperature. When the centrifugal separation running is completed and the rotor is stopped, the control device arranges an elapsed time display column 71 in a setting screen 70A, counts the time since the motor is stopped, and displays an elapsed time 73 after the centrifugal separation running is completed.
