Case Study for Customer Location CA118:
Reservoir or Lake Use:
The tank is an above ground steel tank, 0.6 million gallons (MG), 30 ft high. The Town converted to
chloramine in February 2005.
Reported Problem Before Installation:
Tests prior to installation of the SolarBee indicated that water temperatures differences from the top to
the bottom of the tank varied from 2 - 5° C. This stratification creates unequal water age in the tanks
and promotes undesirable nitrification in chloraminated systems. Therefore, objectives were to
thoroughly mix the water in the tank to prevent stratification, short circuiting and stagnant water
conditions in order to control any potential nitrification events.
Installation:
Date: August 2006, one (1) SB1250v12-PW was installed to mix the water in this tank that historically
has had older water age than other tanks in their system.
Results:
Testing by the Town concluded that the SolarBee is effectively mixing the bulk water inside their tank.
Vertical temperature measurements taken in the fall of 2006 varied only from 15.0°C to 15.5°C with
SolarBee mixing. Operator is very pleased with the proven mixing abilities of the SolarBee and more
consistent chlorine residuals, which has made their conversion to chloramine much easier.
