(1) Mechanical agitation, can be equipped with special air sparger, make mechanical agitation combined with gas litres of mixing, reduce power consumption.

(2) As a core part of flotation column, air-bubble sparger is always the major research emphasis in the design of flotation column.

(3) When the sparger has a bubble cap, the gas holdup becomes high.

(4) The use of sparger can improve the safety of the negative water- supply system efficiently.

(5) The influences of impeller types, baffle configurations and gas sparger on critical speed of floating particle in an agitated vessel were investigated.

(6) In another embodiment, the bioreactor includes a rotational wand mixer and an integral sparger.

(7) Flowing status of catalyst bed are guaranteed by adopting reaming air scattering plate and raw material sparger method decided according to the calculation of the pressure drop of reactor bed.

(8) In addition, the correlations of for some better impeller - baffle - sparger combinations were obtained.

(9) The transient characteristics of saturated steam directly concreting on the surface of sub- cooled liquid when sparger was added to CMT are studied.

(10) In one embodiment, the bioreactor includes a mixer and a movable sparger.

(11) Heating steam shall be introduced into the water stored in the feed water tank through a rake of sparger steam pipes below the minimum water level.

(12) The high flux membrane filtration results that the large size sparger is more benefits to preventing sedimentation and deposition of colloidal suspension on the membrane surface.

(13) Two forced oxidation devices of flue gas desulfurization in power plants are introduced, including fixed air sparger(FAS) and agitator air lance assemblies(ALS).
