BIOJET™ ST Surface Aerators

Equipment for biological process
Low speed surface aerators are available as fixed or floating construction, with the world’s unique onecell floating system. The floating construction is ideal for SBR operation. ST surface aerators used as aerators and mixers as a single unit, with sizes from 850 – 3,000 mm Ø, are designed for high oxygen demand, from 5 – 290 kgO2/h, and high biological rearrangement. Provides deep hydraulic currents within the reactor tank. High efficiency of 1.9 – 2.3 kgO2/kW of oxygen loading and no remission of oxygen demand is guaranteed.

One-cell floating construction
has the advantage of free spreading and splashing without any disturbances as the old fashion 3 cells systems. No anaerobic dead zones. No sediment build-up under the floating tanks.

• Fixed Construction
• Excellent combined aeration and mixing
