Fine Bubble Aeration Systems
The KEE Triton redefines aeration and mixing, all in one simple unit.
High-Efficiency Fine Bubble Aeration & Mixing for Industrial and Municipal Wastewater
Boost the operational efficiency of your biological wastewater treatment plant while significantly cutting energy costs with KEE Fine Bubble Aeration Systems. Powered by the innovative KEE Triton® Aerator/Mixer, our advanced surface-mounted units deliver superior Oxygen Transfer Efficiency (OTE) and complete whole-basin mixing in a single, durable system. Reduce Biological Oxygen Demand (BOD), eliminate dead zones, and reliably maintain regulatory compliance without the maintenance burden of complex submerged pipework.
What is a Fine Bubble Aeration System?
A fine bubble aeration system introduces microscopic air bubbles (typically 2 mm or smaller) into wastewater to supply dissolved oxygen to biological treatment processes. By generating smaller bubbles, the system drastically increases the total surface area of air in contact with water. This maximises Oxygen Transfer Efficiency (OTE) and accelerates the microbial breakdown of organic pollutants.
Key Benefits of KEE Fine Bubble Aeration Systems
- Superior BOD & COD Reduction: High oxygen absorption speeds up biological treatment, achieving up to 99% BOD removal in challenging wastewater applications.
- Drastic Energy Savings: By transferring more oxygen per horsepower than conventional coarse bubble or surface aerators, KEE systems lower power consumption significantly.
- Whole-Basin Circulation: Dual-propeller technology drives fine bubbles horizontally across the entire basin, keeping solids in suspension and preventing sludge settling.
- Low Maintenance & High Reliability: Surface-mounted design allows easy access and maintenance without emptying the basin or replacing underground membrane diffusers.
- Flexible Process Control: Easily switch between aeration and anoxic mixing modes to facilitate combined nitrification and denitrification in a single reactor.
The KEE Triton®: Redefining Aeration and Mixing
Inefficient aeration systems waste power and lead to uneven oxygen distribution. The KEE Triton® Aerator/Mixer solves this challenge by combining fine bubble aeration and deep-basin directional mixing into one surface-mounted unit.
Why Choose the KEE Triton®?
- EPA-Compliant Fine Bubbles: Utilises a regenerative air-assist blower and dual propellers to break air into fine bubbles (< 2 mm), extending bubble hang-time for maximum oxygen transfer.
- Deep Basin Performance: Capable of aerating and thoroughly mixing basins up to 10 metres deep.
- Retrofit & Expansion Ready: Easily retrofits into existing oxidation ditches, lagoons, and aeration tanks to expand capacity and reduce operational footprint.
Frequently Asked Questions (FAQ)
How does fine bubble aeration compare to coarse bubble aeration?
Fine bubble aeration produces bubbles smaller than 2mm, providing significantly more surface area per volume of air than coarse bubble systems. This results in much higher Oxygen Transfer Efficiency (OTE), allowing wastewater facilities to maintain required dissolved oxygen (DO) levels using considerably less blower energy.
What makes the KEE Triton® different from submerged diffuser grids?
Unlike fixed submerged diffuser grids, which require complete basin dewatering for membrane maintenance or repair, the KEE Triton® is a surface-mounted unit. It is easier to install, maintain, and adjust while providing both fine bubble aeration and directional mixing across the whole basin floor.
Can KEE Fine Bubble Systems be used for biological nutrient removal (BNR)?
Yes. The KEE Triton® system can operate in dual modes, aeration with mixing or mixing-only (anoxic), allowing facility operators to alternate between aerobic and anoxic cycles to support both nitrification and denitrification in a single reactor.
