3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 High efficiency rotary aerator
A rotary aerator with safe and reliable operation, superior oxygenation performance and leading energy efficiency within a comparable range with same kind.
3.2 Energy efficiency ratio for rotary aerator
Under specified testing conditions, the ratio of the amount of oxygen delivered to the clean water of which the dissolved oxygen is zero per unit time of the rotary aerator to the total energy consumed by the whole machine.
3.3 Rotary aerator of vertical shaft
A surface aerator that the axis of rotation of the aeration impeller is perpendicular to the horizontal plane.
3.4 Rotary aerator of horizontal shaft
A surface aerator that the axis of rotation of the aeration impeller is parallel to the horizontal plane.
3.5 Impeller aerator of self-suction
An aerator that is installed at the bottom of a pool, the oxygen is filled to water body by means of automatic inhalation.
