Significant cost reduction by switching to oxygen + fine bubbles from the diffuser!
For those who want to reduce oxygen costs in aquaculture! Successfully reduced oxygen consumption from 36L/min to 8L/min in a 300-ton class tank, achieving approximately 78% reduction in oxygen supply costs.
We will introduce a case where the oxygen supply in a 300-ton class aquaculture tank was changed from an aeration pipe system to "oxygen + fine bubbles," reducing the oxygen consumption from 36L/min to 8L/min. The reduction amount is 28L/min, with a reduction rate of approximately 78%. This results in an oxygen usage of about 22% of the conventional amount, leading to a reevaluation of the oxygen supply costs in aquaculture facilities. Our fine bubble system supplies oxygen to the water in the form of tiny bubbles. As the bubbles become smaller, the contact area with water increases for the same gas volume, and the rising speed decreases, making it easier to secure contact time with the water. This mechanism efficiently dissolves the supplied oxygen into the water, supporting the maintenance and improvement of dissolved oxygen (DO) levels. We offer oxygen supply methods tailored to the tank capacity and rearing conditions to address concerns such as "I am using a lot of oxygen, but DO is not stable" or "I want to reduce the burden of oxygen costs."
basic information
【Features】 - Case study on improving oxygen supply in 300-ton class aquaculture tanks. - Changed from oxygen supply via aeration pipes to oxygen fine bubbles. - Reduced oxygen consumption from 36L/min to 8L/min (approximately 78% reduction). - Ensured contact area and contact time between oxygen and water with fine bubbles. - Proposed equipment configuration tailored to tank capacity, shape, and rearing conditions. 【Usage Scenarios】 - Review of oxygen supply methods for large aquaculture tanks. - Reduction of oxygen consumption in facilities using aeration pipes. - DO management in high-density aquaculture. 【Benefits of Implementation】 - Achieved approximately 78% reduction in oxygen consumption in this case study. - Supported reduction of oxygen costs through decreased oxygen consumption. - Assisted DO management by improving oxygen dissolution efficiency. *The reduction rate is based on the results of this case study. Effects may vary depending on operational conditions such as water temperature, salinity, rearing density, and equipment configuration.
