Abstract

The Cultured Abalone, LLC, is a shore-based aquaculture operation located on the Santa Barbara Channel in Goleta, CA. An energy assessment performed by Southern California Edison has identified energy efficiency improvement potential in updating the aeration system. A baseline system of regenerative blowers was used to provide aeration into growing tanks used for abalone and seaweed production. The project scope included replacement of the existing blowers with an efficiency-optimized system sized to provide adequate level of aeration to the tanks. Efficiency gains are achieved by sourcing highly efficient blowers, improving system layout, and enabling precise system tuning via variable-frequency controllers.
