BIOSWEEP™ is a high performance air and surface decontamination system designed to safely eradicate biocontaminants, volatile organic compounds, and off-gassing odours within any unoccupied zone or building. The system combines the latest in airborne and surface contamination destruction technology in one portable unit to produce unparalleled decontamination and restoration capabilities on-site. The process is low-temperature, residue-free, and offers excellent material capability (including sensitive electronics).

The BIOSWEEP™ process employs proven technology called photocatalytic oxidation (PCO) in a five-stage process to produce simultaneous, interrelated forms of oxidation to eradicate airborne organic contaminants. These vapour compounds are unsurpassed in field applications for their penetrating oxidative power to remove virtually any embedded or persistent odour.

BIOSWEEP™ multiphase process:

 

PHASE 1 � Germicidal UV Radiation

Air comes into the bottom rear of the BIOSWEEP™ unit. High intensity germicidal irradiation is lethal to incoming airborne microorganisms, creating peptide bonds within their DNA, preventing them from further replication. All other slices of the UV Band are used as well.

 

PHASE 2 � Powerful Singlet Oxygen and Oxyradical Plasma

A dense cloud of powerful molecular oxidizers attack bio-particles and rapidly begin breaking the carbon bonds that form their cellular matter. Approximately 70% of the system�s energy goes into creating this powerful sterilizing plasma gas, which includes singlet oxygen, superoxide, hydrogen peroxide and three oxyradicals: hydroxyl radicals, the atomic oxygen radical, and hydro peroxide radicals. These agents remain in the chamber.

 

PHASE 3 � Concentrated O3, H2 O2

Purified trivalent oxygen, called ozone, is produced which contributes to oxidization within the chamber and production of more oxyradicals. Bulk ozone and hydrogen peroxide molecules leave the top of the unit to continue their work outside the chamber for another 30-45 minutes before decaying harmlessly back to the natural elements from which they were made.

 

PHASE 4 � Photocatalytic Production of Hydroxyl Radicals

Special nanoparticles coated on the entire inner chamber wall undergo a photocatalytic reaction driven by the UV energy field. They convert water vapour in the air or feed gas into more hydroxyl radicals projecting from the entire inner surface. The new oxyradicals break up passing organic matter and generate more oxyradicals from the O3 concentration present.

 

PHASE 5 � HEPA Filtration, Optional Supplemental Feed Gas
