DualStar BNR Aerator

• The new DualStar BNR Aerator is the result of consistent development of the internationally successful OxyStar Aerator
• The DualStar BNR Aerator combines the two most important functions in wastewater treatment:
  • Effective aeration and simultaneous mixing during the nitrification phase
  • Agitating and mixing without oxygen supply during the denitrification phase
• Problem-free integration in existing plants due to flexible installation possibilities
  • On robust floats for basins with varying water level (SBR-plants, etc.)
  • Or with individually designed mounting brackets
• Model either with a switchable blower or with an innovative automatic shut-off valve
• Heavy-Duty-Model for special applications available

Advantages

• Only one machine for nitrification and denitrification phases
• Cost-reduction due to double function
• Ideally suited for SBR-plants
• Consistently high performance thanks to the clog-proof propeller
• No seals and bearings in submerged machine parts
• Use of high-quality corrosion-resistant materials
• All submerged machine parts are made of stainless steel or GRP
• Minimum noise level, no spray water, no aerosols
• Long lifetime and minimized maintenance requirements
• Easy handling due to low weight
