Stagnation and temperature stratification issues eliminated.
Topics: 500,000 gallon elevated tank, stratification, stagnation, water age
System Overview: This is a small municipal system serving ~3,000 people via 1,300+ connections. Their source water is from a local river.
Disinfectant Type: Chloramine
Tank / Reservoir Build Information:
Tank Type: Elevated Storage
Tank Construction: Steel
Volume (gallons): 500,000
Total Height (feet): 130
Diameter (feet): 50
Project Objectives: To eliminate persistent stratification & stagnation issues and improve overall water quality in the tank.
Solution: GridBee GS-9 Submersible Tank Mixer with SCADA Box option. (August 2018)
Deployment: The Customer performed the installation themselves.
Results: The tank water column is now thoroughly mixed achieving all stated objectives.
Per the Customer- “We installed the unit in August and everything went great. I can honestly say it was more difficult climbing the tower than the entire rest of the installation. The unit is truly “plug and play.”
Topics: Wastewater, complete mix, partial mix, sludge reduction, energy savingsOverview: The City wastewater treatment plant (WWTP) consists of two lagoons. The primary lagoon is a complete mix pond covering 2.8 acres with a 12 ft operating depth and a total volume of 6.9 MG. The secondary lagoon is a partial mix pond with three cells covering 35.2 acres with a total operating depth of 20-25 ft and a total volume of 138.8 MG. Influent to the primary pond is 90% municipal and 10% industrial wastewater, with an...

To limit costs, consider site-specific parameters if installing off-the-shelf trihalomethane removal systems. DISINFECTION by-product (DBP) regulatory compliance requires public water systems to achieve total trihalomethane (TTHM) levels of 80 ug/L (ppb) or less for a locational running annual average throughout a community. Often a water treatment plant`s most cost-effective approach is to continue using the same treatment processes used in the past but strip excess THMs from the treated water by using a spray...
Topics: potable, stratification/water age, chloramine, short-circuiting, ice buildup, nitrification
Overview: The Reservoir is a 2 MG underground storage reservoir (122` x 182` x 13.5` high) that typically holds about 1.5 MG at about 8` deep. Together with a 1 MG plant reservoir they serve the potable needs of about 8,000 residents. The combined reservoir systems service two 0.5 MG elevated storage tanks, North Tower and South Tower. Source water is surface water from a River, and chloramine is the disinfectant...

With increasing human populations comes the corresponding increased need for improving water quality in lakes, wastewater ponds, potable water reservoirs, and other water storage facilities. Providing circulation within water reservoirs of all types has long been known to provide meaningful benefits, but the costs to achieve sufficient circulation through diffused aeration or mechanical mixers has been prohibitively high for water bodies with surface areas greater than 1 to 5 acres, or volumes over several...

As the annual onslaught
of blue-green algae (cyanobacteria) blooms continues to plague fresh water lakes
and reservoirs, the use of copper sulfate to control the problem has become dubious.
After 50 years of pouring innumerable tons of copper into lakes and reservoirs,
the use of this algaecide has increased resistance and resulted in consequential
problems that require more expensive treatment and threaten marine habitats throughout
the world.Although
naturally present in...
