The Development Design of Venturi Type Protein Skimmer for Mariculture Land Base System

The sustainability of mariculture activities is very dependent on how water is managed. One of the important qualities of water is dissolved oxygen which can be dissolved from the diffusion of air bubbles released by the diffuser. The use of conventional aeration (stone aeration diffuser) has problems due to the macro size of the air bubbles. One solution is to use venturi which produces microbubbles. Therefore, this research aimed to analyze the skimmer design using venturi and the resulting dissolved oxygen values. As a comparison, this study also observed dissolved oxygen from the stone aeration diffuser. This research was conducted without using test organisms. The results showed that venturi can create fine air bubbles. The dissolved oxygen value in the skimmer system using the venturi was higher than the stone aeration diffuser.
