Yes, of course. Due to the characteristics of nano bubbles (see Blog – What are the characteristics of micro-nano bubbles? for details), they can be utilized for water treatment to improve water quality.
Purification principle of micro-nano bubbles
When the dissolved oxygen in water increases due to micro-nano bubbles, the activity of aerobic microorganisms is activated and the decomposition of organic matter is accelerated. Anaerobic bacteria are basically inactivated.
Unlocking Cleaner Water: The Essential Role of Dissolved Oxygen
Dissolved oxygen (DO) is a key driver of water purification. Higher DO levels accelerate the breakdown of pollutants, leading to faster and more effective water cleanup. Conversely, low oxygen slows this process significantly.
Micro-nano bubble technology enhances water quality through several distinct mechanisms:
Combating Organic Pollution & Odor
Due to their prolonged presence in water, micro-nano bubbles supply sustained oxygen. This supports robust aerobic microbial activity, which sharply reduces organic pollutants (COD/BOD) and eliminates black, odorous conditions. The process also helps remove toxic gases—such as methane and hydrogen sulfide—released from decomposing organic sediment
Reducing Nutrient Levels in Water Bodies
Micro-nano bubbles exhibit strong adhesion and diffusion, with minimal buoyancy. By oxygenating deeper water layers, they suppress anaerobic breakdown at the sediment level, thereby curbing the release of nitrogen and phosphorus that fuel eutrophication.
Controlling Algal Blooms
Enhanced oxygenation through micro-nano aeration improves habitat conditions for aquatic life while creating an environment less conducive to excessive algal growth.
Enhancing Clarity & Color
Water cloudiness and discoloration often come from suspended solids, phytoplankton, decomposing plant matter, and organic fragments. Micro-nano aeration supports healthier aquatic ecosystems that naturally consume these substances, visibly improving transparency and restoring water’s natural appearance.
Addressing Sediment Pollution
When micro-nano bubbles oxygenate bottom layers, surface sediments become enriched with oxygen, stimulating aerobic microbial metabolism. This accelerates the breakdown of organic pollutants in the sediment, gradually forming an inert, inorganic layer that seals off internal nutrient release.
