Circulators use solar energy

Using the sun’s energy instead of grid power, SolarBee water circulators minimize aeration equipment run-time in wastewater and industrial water reservoirs, which significantly reduces energy costs and helps provide a fast payback. SolarBee solar-powered circulators can supply most of the mixing energy required in virtually any type of treatment pond, reducing the hours that the aeration system must operate. Thorough mixing helps improve regulatory compliance by reducing biochemical oxygen demand (BOD), total suspended solids (TSS), ammonia, odours and sludge buildup.The solar-powered, floating circulators operate day and night with a low-voltage motor and on-board battery system for continuous, energy-efficient water quality improvement. Each solar-powered SolarBee unit requires about 36 watts to operate, but can displace the mixing energy of about 25,000 watts (30 horsepower) of conventional grid-connected mixing equipment in wastewater treatment ponds and reduce carbon dioxide emissions by approximately 148 tons per year.
