A stabilized ozone fog to efficiently sanitize greenhouses and other difficult to clean structures, using micro / nano bubble stabilization and vaporisation control - Greenhouse Sanitisation

英国生产近2000公顷高价值温室保护作物，销售价值接近10亿英镑。这些密集型作物经历细菌和真菌感染性疾病，造成高达1.5亿英镑的损失。对处理的抗性正在增加，化学品的使用越来越受到限制，并且需要长时间的通风才能使有毒残留物消散，这意味着需要一种更有效的温室消毒形式。使用臭氧作为消毒剂是一种可能性，因为它是非常有效的，并分解成氧气。然而，它的高反应性导致其效率的不可接受的变化。我们已经确定了一种方法来创建一个新的稳定的臭氧“雾”，抵抗分解过程中的分布，并达到目标表面一贯的高水平的效力，与最小的表面润湿冷凝。我们相信，我们可以开发一种消毒装置，可以可靠地消毒复杂的温室结构，也可以在植物生长的情况下使用。我们的项目是证明这个概念的可行性，并了解所需的剂量和气溶胶特性。未来开发的技术被设想为可用于处理整个温室，并且还具有手持式单元的实施例，以在需要时处理各个区域;最终，它也可适用于医疗保健和食品仓储。

The UK produces nearly 2000 Ha of high value greenhouse-protected crops, with a sales valueapproaching £1 billion. These intensive crops experience bacterial and fungal infectivediseases, causing losses of up to £150 million. Resistance to treatments is increasing andchemical use is becoming increasingly restricted and also require long airing times to allowtoxic residues to dissipate, meaning that a more effective form of greenhouse disinfection isneeded. The use of ozone as a sanitizer is one possibility, since it is highly effective andbreaks down to oxygen. However its high reactivity causes unacceptable variability in itsefficacy.We have identified a method to create a novel stabilized ozone ‘fog’ that resistsdecomposition during distribution and reaches the target surface with consistently high levelsof potency, with minimal wetting of surfaces by condensation. We believe we can develop asanitization unit that can reliably disinfect complex greenhouse structures and can possiblyalso be used in the presence of growing plants. Our project is to prove the feasibility of thisconcept and to understand the dosage and aerosol characteristics that would be required. Thefuture developed technology is envisaged to be usable to treat an entire greenhouse and alsohave the embodiment of a hand- held unit to treat individual areas when required; ultimately itmay also be applicable to use in healthcare and food warehousing.
