In a process to introduce large quantities of pressurized gas bubbles into a spent process liquid, especially water, the fluid is first pressurized by pump and the gas, especially air, is then forced into the liquid via a diffuser. The pressurized liquid and the gas are then mixed intensively by a number of mixers. The pump and mixers are both driven by a shaft.

The flats (10, 10') are singled off their stacks (8, 8') simultaneously or at timed intervals, taking all or set numbers of flats from each stack in turn for replacing a fresh stack for the first stack after a set number of flats has been singled off. The stacks are arranged in tandem towards the downstream process. The singler (22) has access to both tandem stacking (12, 13) and uses a lifter ...
