Loading the Tank

Reservoir Size:

Potable water tank of 7.5 MG

SolarBee Installation:

In May 2006, four (4) units were installed in this potable tank. In December 2006, thirty-four (34) additional SolarBees were installed in this city's other potable water tanks to ensure that all tanks within their treatment system would have circulation and a means of controlled dosing. In this application, all models of SolarBees (from the SB1250v12-PW to the SB10000v12-PW) were installed in the various size tanks, including the SB1250v12-PW collapsible unit that fits through a 24” diameter opening.

Project Objectives:

The primary objectives of the SolarBees were to thoroughly mix the tank to prevent stratification and control nitrification from occurring. Other objectives included using the SolarBees to provide a more effective and efficient means of injecting disinfection chemicals, when required.

Project Results:

Results from the initial four (4) SolarBees over the 2006 summer showed dramatic improvements in mixing, elimination of stratification, reduction in water age and temperature, and overall water quality. In fact, results were so positive that the City purchased 34 more SolarBees. Now their entire potable water storage system operates with SolarBees. Since the installations, all objectives are being met and the City is pleased with the improved, consistent water quality and the potential for economic and chemical savings.
