Case Study for Customer Location CA107:
Reservoir or Lake Use:
The city’s Water Reclamation System is one of the most extensive in the US, supplying reclaimed water to more than 7,000 acres of agricultural and recreational land. The system includes 12 effluent storage ponds on 700 acres, with a total capacity of 1.5 billion gallons and a flow rate of about 8 MGD.
System Overview and Reservoir:
SolarBees were installed in Cell #2 and Cell #3, 2 of the 12 effluent storage basins. Surface area for Cell #2 has a surface area of 24 acres, with maximum depth of 6 ft. Cell #3 has a surface area of 11.3 acres, with a maximum depth of 4.5 ft.
Reported Problem Before SolarBee Installation:
The basins had a long history of blue-green algae blooms, surface scum buildup, and periodic odors. Objectives were to provide circulation within the effluent storage basin in order to prevent blue-green algae from forming and reduce odors in these shallow ponds.
SolarBee Installation:
Date: Jan 2004, installed two (2) SB10000 in Cell #2 and one (1) SB10000 in Cell #3. All three units were upgraded to SB10000v12 model in January 2005.
Results:
Because SolarBees were installed in only 2 of the 12 effluent storage ponds, side-by-side comparisons between treated and non-treated (control) ponds are possible. Compared to the control ponds, the two SolarBee ponds showed improved water quality and lower pH values. The owner also reported that the SolarBee ponds have had dramatically reduced plugging of their irrigation system’s filter, in contrast to the control ponds that experience frequent plugging due excessive algae growth. Furthermore, odors have been controlled in the SolarBee ponds as well. The owner is very pleased with these results and the performance of the SolarBees.
