Advanced Plasma-Activated Water (PAW) Technology Using Nano TiO₂ Plasma Injection

Introduction

Plasma-Activated Water (PAW) is an innovative and environmentally friendly technology that enhances the physicochemical and biological properties of water through plasma treatment. Our advanced system utilizes Nano Titanium Dioxide (Nano TiO₂) plasma technology, where plasma-generated reactive species are transferred into water via a controlled nano-bubble injection system.

This technology creates highly stable, reactive, and functional water with significant applications in agriculture, poultry production, and food preservation.

Technology Description

In our system, plasma is generated using nano TiO₂-enhanced plasma discharge. The plasma exhaust gas—rich in reactive oxygen species (ROS) and reactive nitrogen species (RNS)—is directly injected into water through a nano-bubble diffusion mechanism.

Why Nano-Bubbles?

Nano-bubbles offer several technological advantages:

• Extremely small size (typically <200 nm)

• High surface area contact with water

• Long residence time in liquid

• Enhanced dissolution efficiency of reactive species

• Improved stability of plasma-activated compounds

Through this process, the water becomes enriched with:

• Nitrates (NO₃⁻)

• Nitrites (NO₂⁻)

• Hydrogen peroxide (H₂O₂)

• Hydroxyl radicals (•OH)

• Dissolved oxygen

The result is a highly active and functional plasma-treated water with antimicrobial and growth-enhancing properties.

Applications

1. Agricultural Greenhouses

In greenhouse systems, Plasma-Activated Water provides dual functionality:

a) Pest and Pathogen Control

• Effective against fungi, bacteria, and certain plant pathogens

• Reduces the need for chemical pesticides

• Eco-friendly and residue-free solution

b) Natural Nitrogen Enrichment

• Plasma injection increases nitrate concentration in water

• Acts as a bio-available nitrogen source

• Enhances plant growth and root development

• Improves nutrient absorption efficiency

This technology supports sustainable agriculture and reduces dependency on synthetic fertilizers.

2. Poultry Industry Applications

In poultry farms, PAW can be used for:

a) Surface Disinfection

• Equipment sanitation

• Floor and environmental spraying

• Reduction of microbial load in production areas

b) Meat Treatment Before Packaging

By spraying plasma-activated water on poultry meat prior to packaging:

• Significant microbial reduction

• Lower total bacterial count

• Inhibition of spoilage organisms

• Extended shelf life in market conditions

Our internal experimental results indicate that shelf life can be increased substantially without chemical preservatives.

3. Food Preservation and Market Shelf-Life Extension

Plasma-Activated Water improves post-harvest and post-processing stability by:

• Reducing oxidative spoilage

• Lowering microbial contamination

• Maintaining freshness and sensory quality

• Extending cold-chain durability

This creates major economic advantages:

• Reduced food waste

• Longer transportation capability

• Improved export potential

Advantages of Nano TiO₂ Plasma Technology

• Chemical-free disinfection

• Environmentally safe

• No harmful residues

• Cost-effective in large-scale operations

• Scalable for industrial use

• Compatible with automated spraying systems

Conclusion

The integration of Nano TiO₂ plasma technology with nano-bubble water injection systems represents a breakthrough in sustainable agriculture and food safety. By transforming ordinary water into a biologically active medium, this technology provides:

• Safer food production

• Reduced chemical dependency

• Increased agricultural productivity

• Extended meat shelf life

• Sustainable industrial disinfection

This innovation marks a significant step toward next-generation eco-friendly agricultural and food processing systems.
