Definitions

  • the invention relates to the field of disinfecting and in particular relates to a method and system for disinfecting a greenhouse and greenhouse related enclosures.
  • Typical greenhouses and greenhouse related enclosures are difficult and time consuming to sanitize using conventional methods such as antiseptic cleaners and the like.
  • Conventional cleaners are comprised typically of chemicals that carry carcinogenic and mutagenic residuals that could harm workers and damage biological controls in a greenhouse.
  • Pathogens such as germs and viruses can remain in the enclosure and infect plants and people without proper disinfection.
  • Ozone is well known as a disinfectant or sterilizing agent.
  • Ozone is a powerful oxidizer which effectively kills microorganisms. Applications in water and waste treatments are well documented.
  • the penetrating property of ozone makes it an ideal aerial disinfectant as well as a surface disinfectant.
  • Ozone is a useful disinfectant of rooms or enclosed spaces and their surfaces, because as a gas it readily penetrates into corners and crevices of an enclosed space.
  • Ozone is an unstable gas comprising three atoms of oxygen. It is unstable because ozone gas will readily degrade back to its stable state, diatomic oxygen (O 2 ), the form of oxygen humans breathe to live, with the formation of free oxygen atoms or free radicals.
  • the free oxygen atoms are highly reactive and will oxidize almost everything, including viruses, fungi, moulds, bacteria, organic and inorganic compounds.
  • Ozone's high level of oxidation properties means that in addition to being a disinfectant, it is capable of eliminating odors caused by animals, smoke, and fuel. Following sanitization with ozone, the sanitized space will be left with a clean, fresh smell.
  • Ozone is considered an environmentally friendly disinfectant, because it is a potent disinfectant at low concentrations, it does not produce any harmful chemical compounds with harmful residues and all residual ozone used in disinfection is converted back to oxygen with carbon dioxide and other minor concentration of gases within a relatively short period of time.
  • Ozone generators are presently available which are marketed to be used continuously in an enclosed space and in the presence of humans and animals to remove odors and freshen the air.
  • the level of ozone generated by these ozone generators is low, since the ozone concentrations must be maintained at levels which will not adversely affect occupants. It is generally accepted that the maximum ozone concentration in an atmosphere occupied by humans for any significant length of time is 0.1 parts per million (ppm), and preferably ozone concentration is below 0.05 ppm.
  • a method of disinfecting a greenhouse enclosure or greenhouse related enclosure may include providing an ozone generator, inserting an ozone delivery conduit from the ozone generator into the enclosure, restricting access to the enclosure to prevent public access, and substantially sealing the enclosure such that air inside the enclosure is substantially prevented from exiting.
  • the method may also include creating an ozone enriched atmosphere within the enclosure by generating gaseous ozone into the enclosure to an effective ozone concentration, for example, between 0.5 ppm to 200 ppm, and monitoring the ozone concentration within the enclosure. Once an effective period of time, for example, between 0.25 and 32 hours, expires, the ozone may be removed from within the enclosure to a level safe for public access.

  • the methods may include increasing the relative humidity within the enclosure during disinfection, increasing the temperature within the enclosure during disinfection, and/or increasing the atmospheric pressure within the enclosure during disinfection.

Abstract

L'invention concerne un procédé et un système pour désinfecter une serre ou une enveloppe associée à la serre. Le procédé consiste à utiliser un générateur d'ozone, à introduire un conduit de distribution d'ozone du générateur d'ozone dans l'enveloppe, à restreindre l'accès à l'enveloppe afin d'empêcher l'accès du public, et à sceller sensiblement l'enveloppe de telle sorte que l'air à l'intérieur de cette dernière est sensiblement empêché de sortir. Le procédé consiste également à créer une atmosphère enrichie en ozone dans l'enveloppe par génération d'ozone gazeux dans cette dernière à une concentration efficace, et à surveiller cette concentration d'ozone dans l'enveloppe. Après expiration d'une période de temps efficace, l'ozone peut être éliminé de l'intérieur de l'enveloppe à un niveau qui ne nuit pas à l'accès du public. Le système peut comprendre un générateur d'ozone doté d'un conduit de distribution d'ozone pour distribuer l'ozone gazeux du générateur dans l'enveloppe, et un dispositif de mesure de concentration d'ozone pour surveiller et mesurer la concentration d'ozone dans l'enveloppe. Le dispositif de mesure de concentration d'ozone peut fonctionner pour communiquer avec une unité de traitement informatique pouvant fonctionner pour communiquer avec le générateur afin de commander la production d'ozone.
