Reservoir Size:
6 ponds/cells totaling 9.7 Acres.
SolarBee Installation:
Date: Jan 2005: Installed six (6) SolarBees total, one per cell. In AL-1, the primary cell which is a total mix cell. 1 SB10000v12 was installed in AL2 and AL3. One each SB10000v12-Dual Mix units were installed; one each SB2500v12 were installed in SS1, SS2, and SS3.
Project Objectives:
Objectives are to improve treatment for removal of BOD, TSS and ammonia, and prevent short-circuiting that was occurring within each pond. Secondary objectives include reducing aeration run time for the aerators in the first three cells, and enhance in-situ sludge reduction.
Project Results:
Water quality improvements occurred almost immediately following the SolarBee installations, with ammonia levels sufficiently reduced to meet regulatory requirements - even in winter. Planada has achieved a 66% energy savings by reducing aeration run time. In addition to the improved water quality and elimination of short-circuiting, the owner also reports significant in situ sludge reduction in the cells.
