Energy-savings and water quality improvement opportunities with SolarBee and GridBee mixers: In wastewater treatment, the aeration system is often the largest energy consumer. In the past, the answer for every problem seemed to be to increase horsepower and add more aeration. When you analyze aeration, typically only 20% to 50% of the energy consumed is needed for production of dissolved oxygen (DO), for the biological oxygen demand (BOD) and nitrification bacteria. The remaining energy is used for the mixing effect, to get the DO to the bacteria that need it.
Each GridBee or SolarBee mixer can typically displace up to 30-50 horsepower of surface aerator mixing (run-time). With the SB or GF performing the mixing, the aeration system can be dialed back to just provide the needed 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.
Many types of industrial water reservoirs have been improved by our GridBee and SolarBee long-distance mixers.
