Case Study for Customer
Location CAN101:
Reservoir or Lake Use:
The lake is used for cooling as part of the operation of a power
plant, a 760 MW coal-fired generating station. The lake is also
used for recreation, and has a beach area and a marina in a
small bay at one end of the lake.
System Overview and Reservoir:
The cooling pond is about 1,300 acres in total surface area with
a maximum depth of about 60 feet. The marina is 4.1 surface
acres, with a maximum depth of about 13 feet and an average
depth of 6-7 feet. Approximately 33% of the lake water is cycled
through the plant each year.
Reported Problem Before SolarBee Installation:
Both the marina, swimming area and the main body of the lake had
a history of persistent blue-green algae blooms and infestations
of the submerged aquatic plant, curly-leaf pondweed (Potamogeton
crispus).
SolarBee Installation:
Date: May 2004, installed one (1) SB10000 solar only in the
center of marina bay. Primary objective was to control
blue-green algae blooms, and the secondary objective was to
control curly leaf pondweed. June 2005, replaced existing unit
with a SB10000v12 unit.
Results:
Blue-green algae blooms have been consistently prevented in the
marina since the SolarBee was installed. Meanwhile, blooms
continue to persist outside of the marina. When fall, seasonal
winds push these blooms into the marina, the SolarBee dissipates
the blooms and good water quality is restored in the marina
within 1-2 days. As for curly-leaf pondweed, when the weeds
started their 2004 fall/winter growth (with biomass peaking in
late spring), divers reported that the plants appeared stunted
and not very healthy. By summer 2005, customer reported a 50-60%
reduction in coverage from the year before. In early April 2006,
customer reported that weeds were not there as they used to be
for the last 12 years, and it has been better each year since
the SolarBee was installed. In addition to seeing fewer weeds,
he reported that remaining plants were not as tall or green, and
appeared sickly in a constant state of dying. They used to need
3 weeks and lots of manpower for multiple weed harvests in the
spring and summer. In 2005, they harvested only one day in the
spring, and not at all during the summer saving considerable
manpower and expenses. In contrast, the rest of the lake had
persistent blue-green blooms and a substantial weed invasion.
The customer is very pleased with the benefits provided by
SolarBee circulation in the marina.
