In wastewater treatment, the aeration system is often the largest energy consumer. It seems the age-old answer for every problem was to increase horsepower and add more aeration. When you analyze aeration, only 20% to 50% of the energy consumed is needed for production of dissolved oxygen (DO) for processing BOD and nitrifying bacteria. The remaining energy is used just for the mixing effect.
With SolarBee® / GridBee® equipment performing the mixing, the aeration system can be dialed back to just provide the needed dissolved oxygen (DO). In most energy saving projects our equipment has a one to three year payback. With electric rates near $0.10 per kwh, savings can approach $750,000 per mixer over 25 years.
SolarBee® SB Series Solar Mixers: SB Series mixers are designed to operate 24 hours per day on solar power, utilizing digital logic for power management, auto-reverse and anti-jam features. These mixers are most typically used where power is not available or when the ponds are large in size.
GridBee® GF Series Grid Mixers: GF Series mixers are the same machines as the SB mixers without the solar equipment; they are designed to operate 24 hours per day on 120v electric power. These mixers cost less and are typically used where power is readily available or when the ponds are smaller in size.
GridBee® AP Series Air Mixers: AP Series mixers combine patented circulation technology with a clog-free air-powered pump. They have no moving parts in the water and no electricity in the water.
