Pre-Deployment Conditions: Thermal stratification, short-circuiting, and inadequate mixing resulted in variable and inconsistent chlorine residuals.
Solution: One (1) SolarBee® SB Series Small Frame potable Tank Mixer per tank. (April 2012)
Results: Thermal stratification and short-circuiting have been resolved and chlorine residuals are consistent. The City is very satisfied with the sustainable water quality benefits solar-powered circulation continues to provide, as well as with ongoing customer service and technical support.
Update (2018): A Medora Service Crew returned to perform a routine maintenance check on the SolarBees. During their examination they found the entire water column thoroughly mixed with no signs of stratification.
