Global Nano Bubble Generator Market Insights, by Type – Venturi Segment Owing to its Superior Efficiency and Versatile Design

The venturi segment is projected to account for 28.3% share in 2025. Industries such as wastewater treatment and aquaculture benefit from the Venturi technology because of its capability to produce stable nano bubbles that improve oxygen transfer efficiency.

Another significant driver is the environmental advantage associated with Venturi nano bubble generators. They add to sustainability goals by improving oxygenation and accelerating pollutant breakdown without the need for chemical additives. In 2024, Cermaq Norway partnered with Moleaer to install Venturi-based nanobubble generators across several sea-pen sites to increase dissolved oxygen and suppress harmful bacteria during warm-water periods. Also, the compact design and scalability of Venturi generators make their deployment possible in both large-scale industrial operations as well as smaller setups like residential water treatment equipment.

Global Nano Bubble Generator Market Insights, by Application – Aquaculture Segment Lead the Market Driven by Critical Oxygenation Needs and Sustainable Fish Farming Practices

The aquaculture segment is expected to capture 30.3% share in 2025. Aquaculture depends on good water quality conditions, especially dissolved oxygen levels, which are very important to the health, growth, and survival of aquatic organisms. Nanobubbles significantly enhance oxygen transfer rates compared to traditional aeration methods. Nano bubbles can stay suspended in water for long periods without rapid surface escape. Fish farms adopting nano bubble generators see reduced fish stress, lower disease incidence, and improved feed conversion ratios, all of which add to higher yields and profitability.

Impact of AI on the Nano Bubble Generator Market:

Artificial Intelligence (AI) is beginning to reshape the global nano-bubble generator market by enabling predictive control, real-time monitoring, and automated optimization of water treatment and aeration systems. AI-driven sensors can track parameters such as dissolved oxygen, pH, and bubble density, then adjust generator output to maintain suitable conditions. Companies are integrating AI analytics into their platforms to help operators remotely monitor performance, forecast maintenance needs, and prevent equipment downtime.

An example is Moleaer’s collaboration with Xylem to deploy Xylem’s AI-enabled water-management software with Moleaer’s nanobubble systems to optimize oxygen transfer and detect anomalies before failures occur.
