Case Study for Customer Location
CA84:
Reservoir or Lake Use:
The reservoir is an enclosed water storage facility for potable
chloraminated water, and is the largest reservoir in their
system. The system converted to chloramines in February 2004.
System Overview and Reservoir:
Surface area is 11.0 surface acres and maximum depth is 30 feet
when full; operating volume is 90 million gallons. There are
1000 roof support columns in the reservoir.
Reported Problem Before SolarBee Installation:
The reservoir had a history of stratification problems,
shortcircuiting, high water age, and dead zones that lead to
high nitrification potential. Primary goal is to provide
complete mixing in order to reduce water age and prevent
nitrification.
SolarBee Installation:
Date: August 2002: Installed two SB10000-PW 10,000 gpm
circulators with 24-hour electric kits, and with horizontal
intake plates set at one foot off the reservoir floor. In May
2005, both units were upgraded to the SB10000v12-PW model. At
the same time, an injection manifold was mounted on the outside
of each dish to facilitate even dispersal for chlorine boosting
and breakpoint chlorination (if needed) after system converted
to chloramine.
Results:
In August 2002, the customer and a leading drinking water
consultant began an extensive, 18-month study on the effects of
operating just one SolarBee SB10000-PW in the reservoir. The
reservoir was allowed to stratify without either SolarBee
operating, chlorine was injected into the reservoir, and then
one SolarBee was turned on. Data from chlorine and temperature
probes located at various depths throughout the reservoir showed
that just one SolarBee was sufficient to eliminate
stratification, boost chlorine, and accomplish breakpoint
chlorination. SolarBee circulation was visibly evident to divers
even into the far corners of the reservoir. By May 2005, the
customer had purchased the two test machines, as well as six
additional SB10000v12-PW units for three other potable water
reservoirs in their system. At the AWWA national show in June
2005, the customer gave a presentation on why they selected
SolarBees for mixing in their large tanks. the customer gave
SolarBee 4 out of 5 stars in mixer ranking, stating that
SolarBee units were identified as the best mixing alternative
for large reservoirs.
