Decontamination Services

ClorDiSys offers decontamination services to provide a sterilization level fumigation of any enclosed space at your facility. We have a wide range of experience within the food industry, having worked in Ready-to-Eat (RTE) facilities, wet and dry dairy facilities, deli's and commercial kitchens, wet and dry pet food facilities, beverage plants, and many other dry processing environments. This biodecontamination can take place for a variety of applications, including:

Contamination response and remediation
Routine preventive maintenance during shutdowns
Establishing sterility after construction
Re-establishing sterility between crops/batches
Recommissioning and Decommissioning of spaces

ClorDiSys' chlorine dioxide gas technology allows for a complete decontamination of your facility, with minimal equipment and minimal downtime. Gaseous systems provide the ability to achieve a complete distribution and thorough penetration to each and every surface within your facility, including visible and invisible cracks and crevices. Chlorine dioxide is safe on materials and leaves no post treatment residuals which allows production to resume quickly upon completion.

Complete Facilites Case Study: A 300,000 ft³ facility was decontaminated that consisted of a small packaging room, a mixing room, and a Dryer Room. The Dryer Room was 70 feet in height and consisted of various processing equipment with access platforms. Even after thorough cleaning and liquid decontamination, a persistent salmonella problem could not be eradicated. ClorDiSys was able to fumigate the facility utilizing chlorine dioxide gas and eliminate the organisms while providing sporicidal kill of Biological Indicators (comprised of bacillus atrophaeus spores) placed throughout the facility to ensure the process was successful.	Rooms and Partial Facilities Single rooms, connected rooms, and other areas within facilities can be decontaminated using chlorine dioxide gas on a routine basis. Chlorine dioxide gas can also be used in contamination response to eliminate any contamination present and quickly return rooms and the equipment within back to production readiness. Typically all equipment and components within a food production facility is compatible with chlorine dioxide gas. By using a gas, all surfaces including cracks and crevices are contacted, allowing for complete decontamination of areas up to 1,000,000 ft³.
Aseptic Filling Areas Case Study A 25,000 ft³ aseptic juice filling facility routinely utilizes chlorine dioxide gas to decontaminate their facility following major maintenance work. This process allows maintenance personnel greater flexibility in performing work and bringing equipment into the aseptic area knowing that it will undergo complete decontamination prior to production being resumed. The facility also conducts chlorine dioxide gas decontamination during scheduled shutdowns, acting as a preventative measure against contamination without causing production delays.	Spiral Freezers Spiral Freezers can be completely decontaminated with chlorine dioxide gas. The limited accessibility which hinders standard cleaning methods does not affect the gas' ability to naturally distribute and contact all surfaces within the chamber. Chlorine dioxide gas is able to decontaminate the crevices, nooks, crannies, and conveyors within the spiral freezer, allowing for the most effective decontamination possible. Decontaminations can be performed upon installation, during scheduled shutdowns, after maintenance work is performed in the freezer, or in the event that a contamination is found within the space.

Tanks and Vessels Case Study: An empty 625,000 gallon aseptic juice holding tank has been routinely decontaminated using chlorine dioxide gas prior to the delivery and introduction of the next batch of juice. This facility switched to chlorine dioxide gas for the decontamination of the holding tanks to reduce the downtime of the tank between batches. Prior to the use of chlorine dioxide gas, the facility would fill the tank with an iodophor where it would reside for upwards of a week. By changing to chlorine dioxide gas, the downtime was reduced to hours.	Transport Containers Transport containers and tanks can be decontaminated with chlorine dioxide gas prior to being filled to ensure sterility of the product during transport. This can replace steam and harsh chemicals saving time and reducing costs.
Piping Piping and vessels can be decontaminated with chlorine dioxide gas prior to use or on a routine basis to ensure sterility of the products inside. Chlorine dioxide gas can also be used in contamination response to eliminate any contamination present. This can replace steam and harsh chemicals saving time and reducing costs.	Laboratories Case Study: A 65 - room, 180,000 ft³ laboratory facility was decontaminated with chlorine dioxide gas prior to its opening to ensure sterility after renovation. Equipment and supplies were brought in prior to the decontamination such that they would be exposed and decontaminated as well. This provided a large time savings as each individual piece of equipment and supply did not need to be treated individually in an autoclave or other pass-through system.
Processing Equipment Rooms and processing equipment can be decontaminated with chlorine dioxide gas prior to use or on a routine basis. Chlorine dioxide gas can also be used in contamination response to eliminate any contamination present and quickly return rooms and equipment back to production readiness. Typically all equipment in a food production facility is compatible with chlorine dioxide gas. By using a gas, all surfaces including cracks and crevices are contacted, allowing for complete decontamination of areas up to 1,000,000 ft³.	HVAC Ductwork Ductwork and HVAC systems, including HEPA housings, can be decontaminated using chlorine dioxide gas. In fact, chlorine dioxide gas is the only residue free fumigation method that can successfully decontaminate HVAC ductwork as it does not condense out along the path length.

Decontamination Chambers Passthrough rooms and chambers are able to be decontaminated using chlorine dioxide gas and allow for a quick and easy method for bringing equipment and supplies into an aseptic facility without manual wiping. By using a gas, all surfaces including cracks and crevices are contacted ensuring a complete and thorough decontamination.	Lyophilizers Lyophilizers can be decontaminated with chlorine dioxide gas prior to use or on a routine basis to ensure sterility. Chlorine dioxide gas can also be used in contamination response to eliminate any contamination present.
Transport Vehicles Transport vans and vehicles can be decontaminated using chlorine dioxide gas prior to use, as contamination response, or routinely for contamination prevention.
