ATB-AQUA 8 surface aerator (8-M, 8-T)

Product description

  • Direct drive high efficiency floating device for aeration and mixing of wastewater in activated sludge WWTP
  • Fine bubble formation due to optimal transfer of kinetic energy on the water surface
  • Two-part float with motor and propeller
  • Guiding in the basin by 2 vertical stainless steel chains

Materials

  • Motor housing made of stainless steel
  • Propeller made of PE (AQUA 8-M) or stainless steel (AQUA 8-T)
  • Float and spray cone made of PE
  • Immersion tube, fastening material and guiding chains made of stainless steel

Working principle & Applications

The AQUA 8 generates an upward directed flow by its propeller. The accelerated water hits the baffle plate, which is located just above the water line, there it is deflected horizontally and generates a highly turbulent flow on the water surface. The turbulence creates extremely fine air bubbles, which are then pushed downwards by the flow. The result is an excellent oxygen transfer. The generated cylindrical flow leads to a perfect oxygen dispersion and at the same time to a complete mixing of the tank.

Applications:

  • SBR plants
  • Activated sludge plants
