FROM:	Mary Willett, ERG

		Cortney Itle, ERG

DATE:	August 29, 2008

SUBJECT:	Meeting with BioKleen Technologies Representatives on August 7,
2007

On August 7, 2007 EPA and ERG met with BioKleen representatives to
obtain information from BioKleen concerning their wastewater treatment
technology.  Attendees at the meeting included:

Brian D’Amico, EPA

Eric Strassler, EPA

Mary Willett, ERG

Cortney Itle, ERG

Kennard Sy, BioKleen

Thomas Hickey, Advanced Aeration

The following topics were discussed:

Overview of the Wastewater Treatment Technology by BioKleen

Dr. Sy provided a presentation on BioKleen’s aeration wastewater
treatment technology.  

Some of the main topics/points made during the presentation included the
following:

BioKleen’s Vacuum Bubble® aerators address BOD and waste treatment
problems by improving the performance of aerobic bacteria.  The
treatment process makes additional oxygen readily available by creating
large populations of very small bubbles (0.25 mm) under a partial
vacuum.  The Vacuum Bubble Technology® (VBT) increases the potential of
oxygen transfer as the small  bubbles remain in the water longer.  This
technology is used in BioKleen’s Deployable Aerobic Aqueous Bioreactor
(DAAB).  

The DAAB treatment unit creates a biofilm that resides on a fabric
substrate.  The DAAB is capable of treating 25,000 gal/day of septic
system wastewater.  Currently 2,300 DAAB treatment units operate at
dairies and municipalities (sludge treatment).  For municipal wastes,
the operational cost for the system is $0.10/gallon.

Application of Technology to Deicing Stormwater

Dr. Sy discussed the application of the BioKleen aeration wastewater
treatment technology to deicing stormwater.  The discussion is
summarized below. 

1.	Laboratory tests on 1% to 8% propylene glycol wastewater achieved 95%
reduction in the concentration of propylene glycol.  BioKleen is working
to increase the propylene glycol concentration in the tests.  BioKleen
acclimates bacteria for propylene glycol wastewater in the laboratory.

2.	The maximum treatment capacity of the technology for deicing
stormwater applications is unknown.  The small footprint of the unit
would allow adding it to a frac tank.

3.	A pilot test of the technology is planned at Newark airport.
