Ultrafine and nano-scale bubbles enhance efficient oxygenation in greenhouse facilities.
2026-06-15
The ultramicro‑nanobubble generation device, serving as the core oxygenation unit of a fully automated hydroponic greenhouse facility, is providing critical support for large‑scale production at a renowned agricultural technology company in Shandong. In this state‑of‑the‑art plant, the nutrient‑solution recirculation system supplies all the water and nutrients required for crop growth, while the ultramicro‑nanobubble generator is seamlessly integrated into this vital process, precisely delivering dissolved oxygen to the nutrient solution and effectively eliminating the risk of root hypoxia and root rot.

Compared with conventional aeration methods, this technology offers distinct advantages: the bubble diameter is reduced to the nanoscale, allowing them to remain suspended in water for an exceptionally long time, while oxygen transfer efficiency increases exponentially. It sustainably maintains dissolved oxygen levels in the nutrient solution at near‑saturated concentrations, ensuring that even in high‑temperature, high‑humidity greenhouse environments where dense root systems rapidly consume oxygen, every plant’s roots can breathe freely and stay vigorously active. Moreover, the charged surface of nano‑bubbles and the micro‑jets released upon their collapse gently cleanse root surfaces and inhibit the proliferation of pathogenic microorganisms, achieving a three‑in‑one effect: oxygenation, root stimulation, and disease prevention. The equipment operates under fully automated control, requiring no manual intervention, seamlessly aligning with the intensive production rhythm of fully automated greenhouse facilities and safeguarding the nutrient‑solution system in an efficient, stable, and environmentally friendly manner.
