Micro-nano bubbles, characterized by their large specific surface area, negatively charged surfaces, long retention time, and the release of hydroxyl radicals upon rupture, achieve green and efficient cleaning in the field of sanitation. They are widely used in food processing, precision industries, membrane systems, medical and pharmaceutical applications, and domestic cleaning, significantly reducing reliance on chemical agents. Below are the specific applications and technical highlights:

Core Application Scenarios and Effects

Food Processing and Cleaning

Fruit and Vegetable Cleaning: Penetrates into the uneven and creviced areas of strawberries, broccoli, etc., removes pesticide residues (removal rate over 84.8%), eliminates E. coli (99.9%), extends shelf life by 5-7 days, and reduces the need for chemical detergents.

Aquatic / Meat Processing: Breaks down blood, water, and fishy odor compounds, removes surface microorganisms, and reduces residues such as nitrites and cholesterol.

Tableware / Equipment Cleaning: Replaces high-temperature steam or chemical disinfection, with no residue and low energy consumption, suitable for CIP online cleaning, reducing production changeover cleaning time.

2. Precision Industrial Cleaning

Semiconductors / Electronics: Used for cleaning 14nm and below process wafers, liquid crystal panels, and optical lenses, with a particle removal rate of over 99.9% for particles below 100nm, reducing defect rates by 40-60% and minimizing surface damage.

Mechanical components: Deep cleaning into tiny gaps and cavities, efficient oil-water separation and grease removal, reducing cleaning time for stamped parts and minimizing detergent usage.

Precision instruments: For fine surfaces such as optical mirrors, the roughness change after 1,000 cycles is less than 0.1nm, outperforming ultrasonic cleaning (85-95% particle removal rate).

3. Membrane and Filter Media Cleaning

Suitable for ultrafiltration, microfiltration, RO membranes, and filter media, it addresses organic/inorganic/biological composite fouling and boundary layer blockage issues.

Reduce the boundary layer, increase porosity, enhance interfacial disturbance, and improve adsorption force with a small amount of surfactant to restore membrane flux, extend lifespan, and reduce the frequency and damage of chemical cleaning.

4. Medical and Pharmaceutical Cleaning

Medical Device: Efficient Sterilization (Achieves a 99.999% inactivation rate of E. coli within 5 minutes), removes residual disinfectants such as glutaraldehyde and odors, compliant with GMP requirements.

Pharmaceutical and Chemical CIP: Thoroughly cleaning "dead zones" (e.g., roughness >1μm depressions) in reactors, pipelines, valves, etc., adsorbing positively charged APIs and microorganisms, generating hydroxyl radicals upon bubble collapse to oxidize and decompose residues, thereby reducing cross-contamination risks.

5. Civil and Daily Chemical Cleaning

Home Cleaning: Effectively tackles stubborn grease stains in the kitchen and persistent stains on clothing, promoting water-oil separation. The cleaner achieves a 99% removal rate, reduces detergent usage, and is gentle on hands.

Personal Care: Deeply removes excess oil from pores and hair roots, achieving a 99.9% oil removal rate while boosting skin hydration by 174%, combining cleansing and moisturizing benefits.

Typical process configuration

Generate micro nano bubbles (10nm-100 μ m), equipped with a cleaning tank or spray system.

It can cooperate with ozone to enhance sterilization and odor decomposition, achieving the integration of "cleaning disinfection sterilization deodorization".

Weak acidic micro nano bubble water is commonly used for membrane cleaning, with a pH increase of 1-3 compared to traditional methods, reducing membrane damage.

Micro nano bubble cleaning is mainly based on physical effects, taking into account high efficiency, greenness, and low damage. It is suitable for diverse cleaning needs from macro to micro, especially for scenarios with high cleanliness and low residue requirements. It is an important development direction of cleaning technology.
