WHAT IS LARGE BUBBLE VERTICAL MIIXNG?

  • THE PERIODIC INJECTION OF COMPRESSED

AIR INTO THE BOTTOM OF A TANK TO CREATE BUBBLE MASSES > 6 “ IN DIAMETER.

  • THE BUBBLE MASSES RISE TO THE SURFACE

PULLING LIQUID AND SOLIDS IN THEIR WAKE.

  • LARGE CONVECTION CELLS ARE CREATED THAT

SCOUR THE SIDE WALLS AND BOTTOM OF THE TANK.

ANCILLARY BENEFITS OF LARGE BUBBLE MIXING IN BNR BASINS

  • ENERGY – EFFICIENT MIXING
  • LOW MAINTENANCE
  • PREVENTS SEDIMENT ACCUMULATION
  • INCREASES ACTIVE TANK VOLUME
  • ELIMINATES SEPTICITY
  • IMPROVES SOLIDS CONTACT IN BASINS
  • IMPROVES OXYGEN TRANSFER IN OXIC ZONES
  • INCREASES BIOLOGICAL ACTIVITY
  • REDUCES SOLIDS LOADING RATE TO SECONDARY CLARIFIERS
  • REDUCES RAS PUMPING REQUIREMENT
  • REDUCES FILTER LOADING AND BACKWASH
  • REDUCES CHLORINE DEMAND OR UV ENERGY DEMAND
