1 Global Nanobubble Generator Market Insight Analysis
The global nanobubble generator market is valued at USD 46.89 million in 2024, with a CAGR of 13.17% from 2024 to 2033.
A nanobubble generator is a device that produces nanobubbles—extremely small gas bubbles with diameters ranging from 70 to 120 nanometers. These bubbles are significantly smaller than a grain of salt and possess unique properties such as a strong negative surface charge, which allows them to remain stable in liquids for extended periods. Nanobubbles are neutrally buoyant and can enhance water quality, improve oxygen transfer, and facilitate chemical-free water treatment processes. Their ability to collapse and release hydroxyl radicals makes them effective in removing pollutants and pathogens from water.

2 Nanobubble Generator Market Growth Drivers and Restraints
The driving factors for the growth of the nanobubble generator market are mainly due to its unique product characteristics and extensive demand in multiple fields. From the perspective of product characteristics, the diameter of nanobubbles is about 1/2500 of salt particles, less than 200 nanometers, with a strong negative surface charge, can be stably suspended in liquids, can effectively improve water quality and strengthen water treatment processes. In agricultural and industrial applications, it can improve production efficiency.
For example, in aquaculture, nanobubbles can improve feed conversion rate and fish biomass; in agricultural irrigation, it can improve water quality, promote crop root health, and improve nutrient absorption efficiency, which has led to a growing demand for nanobubble generators in aquaculture and agricultural irrigation.
The increasingly severe water quality problem is also driving market development. With the acceleration of industrialization and urbanization, water pollution has intensified. Every year, a large number of people are sick or even die due to water pollution, and most sewage is directly discharged without treatment. Nanobubble generators can remove pollutants, reduce pathogens, and decompose biofilms without chemical agents, which can effectively improve water quality and bring development opportunities.
However, the growth of the nanobubble generator market is also facing many limiting factors. On the one hand, the fluctuation of raw material prices has a greater impact. Its main raw materials are stainless steel, etc. The cost of raw materials accounts for a high proportion of the total cost. The changes in market supply and demand and the promotion of the capital market have caused frequent fluctuations in raw material prices, making it difficult for enterprises to stably control costs, which in turn affects product prices and market competitiveness.
On the other hand, the industry is highly competitive. Many companies have increased their investment in research and development, carried out product innovation, expanded channels and strengthened customer relationship management to compete for market share. New entrants face high competitive pressure, and companies that lack industrial chain advantages and precise positioning find it difficult to gain a foothold. In addition, the COVID-19 pandemic has also had a certain impact on the market.
The blockade policy during the pandemic has affected the supply of raw materials and product export trade. The social distance policy has increased the production costs of enterprises. Some factories are even facing the risk of suspension of production. Although automated production and Internet of Things technology may bring opportunities in the long run, market development is still hindered in the short term.
3 Technological Innovations in the Nanobubble Generator Market
Technological innovation in the nanobubble generator market mainly revolves around product performance improvement and application field expansion. In terms of performance improvement, companies continue to improve technology to optimize the generation and characteristics of nanobubbles. For example, the industrial-scale nanobubble generator developed by Moleaer can improve gas utilization efficiency and enhance various process effects. Its Bloom series of products can enrich irrigation water with dissolved oxygen and nanobubbles, promote healthy growth of crop roots, improve nutrient absorption efficiency, and play an important role in the agricultural field.
acniti’s high-concentration GaLF nanobubble generator uses advanced technology to produce the highest concentration of nanobubbles in the industry, and can use a variety of gases. It is equipped with a PLC control system that can accurately control pressure and flow to meet the needs of scientific research and other fields for high-concentration nanobubbles.
In terms of application field expansion, the nanobubble generator launched by Rapid Water Technologies can convert non-condensable gases in water into a large number of nanobubbles, remove and prevent biofilm accumulation in commercial and industrial water, improve heat exchange efficiency, reduce the use of chemical agents and equipment maintenance costs, and expand the application of nanobubble generators in industrial water treatment.
In terms of corporate mergers and acquisitions, Moleaer received a round C financing led by Apollo in 2022, with participation from Husqvarna Group and existing investors, with a financing amount of US$61 million. This financing will help Moleaer expand its production scale, further promote its nanobubble technology, and enhance its market competitiveness.
Although there are few large-scale mergers and acquisitions in the market, with the development of the industry, companies may integrate resources through mergers and acquisitions in the future to achieve technological complementarity and market expansion. For example, companies with advanced technology may acquire companies with extensive market channels to accelerate product promotion; or companies may acquire key technologies through mergers and acquisitions to enhance their own R&D capabilities, thereby gaining an advantage in the fierce market competition.
