Gaia, a global leader in Ultra-fine Nanobubble technology, has collaborated with the Department of Agriculture and Biosystems Engineering at The University of Arizona (UA).

 

University of Arizona’s Isaac Hung demonstrated the potential benefits of injecting ozone gas, with Gaia’s ultra-fine nanobubble technology, to disinfect and reclaim wash water utilized in agricultural harvesting processes.

 

Conventional methods of washing freshly harvested produce use chemicals such as chlorine and large volumes of valuable water that are delivered from natural sources. Because of this processing approach, the wash water is normally discharged into wash basins or sewer systems after one use incurring extraordinary costs due to the processor’s disposal fees and their inability to recycle reclaim water for reuse. This wastewater contains disinfectant residuals, such as chloramines, chlorine, and chlorine dioxide. Such disinfectants preclude the wastewater from being recycled for other agricultural applications.

 

Ozonated water is approved by the USDA as an alternative to chlorine-based disinfection, most notably with Organic Certified Produce. The application of ozone in harvest processing is a disinfection solution without any residual chemicals, granting processors the opportunity to reuse the reclaimed water in processing and other agricultural activities. The nature of the ozonated water produced with Gaia ultra-fine nanobubble technology (0.1 microns or 100 nanometers in size) possesses an electrical charge on the outer shell. This electrical charge results in deeper cleaning and superior disinfection. With the added benefit of zero residual ozone due to the it’s short half-life, the ability to reclaim and recycle wash water results in lower costs, lower energy use and overall lower water usage.
