The Nov. 29 editorial “Stop mixing, start fixing Jordan Lake” stated that rules limiting new nutrient inputs into lakes “for protecting waterways have been effective” at curtailing algal blooms. They have not... Read More
The Metropolitan Water Reclamation District of Greater Chicago’s (MWRD’s) new Thornton Composite Reservoir has come to the aid of local waterways and area basements by capturing 400 million gallons of combined sewer overflow. The level reached 17 feet and five percent of the reservoir’s capacity.Time lapse video footage of the first fill can be found at https://youtu.be/HnOlXJxjDxk.
Lagoon-based wastewater facilities can trace as much as 90% of their electric
bill back to aeration, so the potential for saving money with subsurface
mixers is substantial. Efficiency Vermont is here to help...

Known for "Healing Waters," Pagosa Springs Restores Potable Water System With Help From SolarBee Mixers
Pagosa Springs, Colo. – Located in the high desert plateau of southwestern Colorado, Pagosa Springs is famous for its geothermal hot springs, which draw visitors worldwide to soak in the mineral-rich water. The Utes called the sulfur springs “Pah-gosah,” meaning “healing waters.” You might say the town’s potable water system is healed now as well.
Harmful blue-green algae blooms (HABs) in lakes have made headlines this summer throughout the country. HABs can disrupt municipal potable water systems, forcing residents to rely on bottled water, and have closed beaches on many recreational lakes. Worse than looking and smelling bad, HABs can also cause nausea, diarrhea, skin and throat irritation and breathing difficulties for people; for their pets, the toxins can cause death.
Solar Bees are buzzing at West Lake.
On April 9 and 10, two Solar Bee units were installed into the lake.
“They’re trying to concentrate up around the intake (areas) going into the plant,” said Osceola Water Superintendent Brandon Patterson.
Solar Bees, which look like pumps or fountains that disperse water, are solar powered and placed in lakes to provide long distance circulation, which helps control harmful blue green algae blooms, reduces taste and odor issues, improves fish habitats and overall water quality.
Water and wastewater utilities can account for nearly 40% of a small city's energy use. By more efficiently managing its energy use, a community can significantly affect operational costs and improve its financial sustainability.
Proper mixing increases detention time by adding a vertical plug-flow element to the flow of water through a chlorine contact tank. The increased detention time allows a plant operator to use a higher baffling factor used in contact time (CT) calculations, thus reducing the concentration of chlorine needed to meet CT treatment requirements.
