This document discusses potential commercial opportunities for Avantec's M2R technology, which uses membrane technology to generate chlorine dioxide for disinfection. Some key opportunities discussed include: 1) Using the M2R in poultry processing plants for surface sanitation and in chilled water tanks. 2) Developing a bio-security truck wash system with a partner to disinfect trucks and prevent spread of diseases. 3) Creating an on-site wastewater disinfection system with Ohio State University to treat wastewater from homes before irrigation or disposal. 4) Applying the M2R technology in cooling water treatment for buildings, schools and hospitals as well as for surface sanitation and

2. Avantec’s M2RTM
• Avantec has developed the M2R™ Reactor which uses
membrane technology to generate chlorine dioxide and
other antimicrobials in a controlled-release manner where
water or moisture is present.
• The M2RTM
is a patented, portable, shelf-stable device for
small and medium scale point-of-use applications of ClO2.
• Avantec’s M2RTM
can generate and deliver chlorine dioxide
in either aqueous solution or as a gas in air.

3. Food Processing Plants
• Poultry Plants
– Surface Sanitation
– Chilled Water Tanks
• Bio-Security
– Ensure protection against avian flu viruses in
every step of poultry breeding and processing
– Disinfect cages, transportation vehicles, factory
equipment, etc.

4. Bio-Security Truck Wash:
Potential Market Opportunity
• Avantec is currently
working with a potential
partner to develop a
bio-security truck wash
system using Avantec’s
M2RTM
ClO2 disinfection
technology.
• The developed system will be employed to disinfect trucks
entering/leaving animal farms and international borders to
ensure public safety against pathogenic microorganisms
(e.g. avian flu).

5. On-Site Wastewater Treatment
• More than 25 million homes in the US without access to
community sewage systems use on-site treatment systems
to process their wastewater
--The Groundwater Foundation
• These systems take advantage of natural processes to
remove contaminants from water entering the groundwater
system
• Used in the disinfection step of on-site wastewater
treatment, chlorine dioxide effectively kills bacteria, viruses
and oocysts before they can be released into the
environment
• The market potential for Avantec’s M2RTM
in on-site
wastewater treatment is over $9 billion/ year.

6. On-Site Wastewater Disinfection System
• Avantec is collaborating with The Ohio State University and United
States Geological Survey to develop an on-site wastewater
disinfection system using Avantec’s M2RTM
ClO2 technology.
• An automatic pouch dispensing device is being developed and will
be integrated into the system for precise ClO2 dosage for wastewater
disinfection before discharging to irrigation field.
• This system would only require monthly servicing and maintenance
• Avantec and OSU will share the patent for this system

7. Institutions
• Cooling water treatment for
– Buildings
– Schools
– Hospitals
• Surface sanitation
• Odor control in hospitals
– Chute rooms where bio-hazardous refuse is thrown

8. Paints and Coatings
• As manufacture of water-based paints and
coatings increases, products are needed to
prevent microbial growth in equipment and
piping
• Biofilm buildup in piping joints and along
surfaces in storage tanks will lower
manufacturing efficiency as well as
potentially contaminate products.
