Abstract: Systems and methods of reducing airborne contaminants, such as airborne microorganisms, including bacterial, viral, and fungal microbes, in an indoor space are disclosed. The method includes positioning a portable photo-catalytic oxidation system proximate a source of contaminants in the indoor space and activating the photo-catalytic oxidation system to circulate air through the photo-catalytic oxidation system at a rate ranging from approximately 16 to approximately 24 air exchanges per hour in the indoor space. The photo-catalytic oxidation system is configured to oxidize contaminates in the air.

Abstract: A filter configured to photocatalytically oxidize target compounds in an air stream includes a support structure having an air permeability greater than approximately 155 CFM/ft2 and a photocatalyst supported by the support medium.

Abstract: A method and apparatus for implementing pathogen reduction within a poultry processing or food processing plant that uses water that has been treated with chloramines at an advantageous dosage before being introduced to the production process at processing steps. The water treated with chloramines may be from a fresh water source or reclaimed water from the processing plant. The reintroduction of the treated reclaimed water advantageously causes a dramatic reduction in the levels of microorganisms associated with poultry processing, while substantially conserving water use.

Abstract: A method of hydrolyzing peptide bonds in waste material from dissolved air flotation (DAF float) wastewater treatment systems is disclosed. The method according to the disclosure comprises controlling the pH of said DAF float; adding a lytic agent to said pH controlled DAF float; and incubating the lytic agent/DAF float mixture. The hydrolyzed peptide bonds allow for the cleaving of oil molecules from protein material thereby increasing oil extraction from wastewater streams.

Abstract: The inventions of the present disclosure are directed to processes designed to recover water used in certain aspects of the processing of poultry, treat the recovered water to remove solids, fats, oils and greases, animal proteins and pathogenic organisms and to reuse the treated water for poultry processing operations. The processes described herein reduce bacteria and microorganisms associated with the poultry and reuse water. The present disclosure can be employed with an approach that includes unexpected positive results of reacting ozone and chlorine with water being treated for reuse to generate hypochlorous acid and/or other effective biocides. Ozone reacts with fats, oils, and greases, dissolved in the reuse water, to produce specific surface-active agents and surfactants which reduce the surface tension of the water which it is dissolved.

Abstract: This invention is directed to processes designed to recover water used in certain aspects of the processing of poultry, treat the recovered water to remove solids, fats, oils and greases, animal proteins and pathogenic organisms and to reuse the treated water for poultry processing operations. Although the reuse points will vary from plant to plant depending upon specific water consumption volumes, type of processing operations conducted by the facility and regulatory requirements and approvals, there are a number of reuse points which are preferred based upon treated water quality requirements, material balances relating to the capacity to recover process streams and the consumption volumes at the identified reuse points, and source waters that have been shown to have the least total contaminant loading.

Abstract: The presently disclosed disinfection process for use in the processing of foodstuffs is designed as an intervention step in poultry processing to allow for continuous on-line processing of poultry carcasses that may have accidentally become contaminated during the evisceration process. Such on-line processing is designed to replace the need for off-line manual washing and cleaning of the contaminated carcasses. By eliminating such off-line manual washing, food safety will be enhanced due to the elimination of the physical handling of carcasses and the cross-contamination that may result from such physical handling. An additional benefit is that the production process will also be able to run with a reduced number of interruptions, which will result in a more efficient production process.

Abstract: A semiconductor catalyst is metalized in situ on a reaction support surface by illuminating at least a portion of the catalyst in the presence of a suitable source of metal to selectively deposit the metal on the illuminated portions. The source of metal can be applied to the reaction support surface either with the catalyst or separately, but is not attached to the catalyst until the structure is illuminated. This causes the metal to be deposited where the catalyst will be illuminated during use and therefore where photopromoted catalytic degradation can occur.

Abstract: A fibrous matte web is used to support a semiconductor catalyst for use in the photopromoted catalyzed degradation of compounds in a fluid stream. The catalyst, which may be a transition metal oxide, is affixed to at least one side of the matte web, and preferably the downstream side thereof. In one embodiment, the matte web is comprised of a plurality of fibers of glass or other suitable material permitting fluid to pass therethrough, and the side or sides containing the catalyst are directly illuminated by a suitable light source.
