GridBee AP Air-Powered Mixers and Circulators combine patented high-flow Long-Distance Circulation technology with a clog-free, air-powered pump. They have no moving parts in the water, offering years of maintenance-free operation even in high MLSS (mixed liquor suspended solids) applications. These machines feature an adjustable intake depth and are perfect for mixing activated sludge reactor basins, and other aerated and anoxic wastewater basins of all types and sizes. The air can be supplied by the customer's existing air system or by our optional on-shore blower. These powerful mixers are compact, lightweight, and easy to install by plant personnel. These low-priced mixers have a fast payback in energy savings, and low-cost rentals are available.

Wastewater Benefits:

  • Energy-efficient; with the Air-Power unit doing the mixing, the aeration system can be turned down to provide just the needed dissolved oxygen (DO)
  • Cost-effective with or without the blower
  • Clog-free, self-cleaning design minimizes maintenance with no moving parts in the water

Lakes, Raw Water Reservoirs, and Estuaries Benefits:

  • Can be deployed for blue-green algae (BGA) control or hypolimnetic oxygenation
  • Aesthetically pleasing; mostly submerged except for float balls, can be easily disguised with artificial rocks or plants
  • Small footprint (6 feet diameter or less) reduces boating interference
  • No electricity in the water for swimmers; safer for humans and pets
  • Easy to mount on the end of docks
  • Excellent for de-icng marinas

Stormwater Benefits:

  • Thorough mixing provides increased detention and improved nutrient reduction
  • Effective control of blue-green algae and odors
  • No electricity in the water; safer for humans and pets
  • Low lifecycle cost when compared to fountains

Electrical Service To Be Supplied By Owner:

  • US: 120-240 vac, 1 ph, 10-20 amps depending on mixer size, 60 Hz; 3 ph motors available
