Dungeness Services
Business: Dungeness’s core business is the manufacturing and marketing
of chitosan products for water purification.
History:
Dungeness was formed by chemists, construction managers,
and water treatment professionals in January 2009 as a
division of Dungeness Development Associates, Inc.
Personnel: Dungeness employees have one-hundred years of combined
experience in chitin and chitosan. Chitosan-based water
treatment technologies were developed, tested, perfected and
proven to be highly effective by the staff of Dungeness.
Future:
Dungeness sees a growing demand for water purification
technologies throughout the world and will continue to
develop practical new solutions to meet these needs.
Offer the best industrial grade chitosan products on the
market.
Continue to innovate and develop practical solutions to
water quality issues.
Lead the way toward a healthier environment through our
actions while on the job, at home or in the community.
Educate and guide others in order to enable them to
perform the steps needed to protect our waters.
Form long lasting partnerships with companies and
individuals who share our philosophy.
We subscribe to an unwavering commitment to fairness in business
dealings with our partners and fairness with our customers.

Associates, Inc
East Point
since 1948
East Point Seafood makes its home in South Bend, WA – a small town,
known as “the oyster capital of the world” located on the banks of the
Willapa River.
Erling Bendiksen purchased the cannery in 1942 and established East
Point Seafood.
East Point quickly gained a reputation for superb oyster, salmon, tuna,
sturgeon, dungeness crab and shrimp products.
Joel Van Ornum started Dungeness Development Associates, Inc. in
1988 and purchased East Point.
Joel continues East Point’s commitment to quality seafood products.
Only processor of wild caught cold water Pacific tiny shrimp in the U.S.
East Point now processes a variety of seafood products fresh, frozen
and canned.
1966 Lee Johnson investigates shells in Kodiak, Alaska.
1972 Pilot plant built in Seattle: Kypro Co.
1982 Joel Van Ornum and Lee Johnson construct a Chitin and chitosan
Production Facility in Raymond, WA.
1989 Joel and Lee start Vanson Chemical Co.
1995 Joel establishes Vanson L.P.
1995 Vanson quickly begins turning a profit.
1997 After quadrupling the sales of 1995 in 1996, Van L.P. is converted
into a corporation and Vanson, Inc. is born.
1998 Vanson develops and markets Liposan Ultra.
1970 – Quintin Peniston and Lee Johnson’s “Method for Treating an Aqueous
Medium with Chitosan and Derivatives of Chitin to Remove an Impurity” patent
published.

Chitin
Structural component in the
exoskeleton of crab and shrimp
shells.
Found also in squid, krill, fungi,
and insects.
Second most abundant polymer,
next to cellulose.
Easily chemically modified
Chitosan
Deacetylated derivative of chitin.
Natural cationic polyelectolyte.
Renewable resource.
Very effective coagulant/flocculent due
to its long chain length and strong
cationic charge.
Used in water clarification for decades
The molecules of chitin
and chitosan are
similar to cellulose; all
are long chain
molecules that are
carbohydrates. “Chitin
is the animal form of
cellulose.”

Automation
Dungeness has designed, installed, operated and maintained dozens of active
treatment systems across the U.S. and Canada.
Components include: chitosan injection, sand-filter, pumps, tanks/ponds,
interconnecting plumbing and monitoring equipment.
Certification required to operate a CESF system in WA state.
Proven effective
Minimal labor required
Cost effective
Recognized by EPA
Training available
Less energy required
Dungeness had designed, installed, operated and maintained many passive
treatment systems across the U.S. and Canada.
Passive-hybrid techniques may require minimal mechanical energy.
Components typically include: applicator, cartridge, tank/pond, interconnecting
plumbing, pump (for passive-hybrid techniques), filtering device.
Proven powerful, safe and effective water treatment polymers.
Available in a water soluble slow dissolving solid and liquid
solution.
ChitoVan LC
ChitoVan CA Series
Passive Treatment Cartridge Active Treatment Solution
Other ChitoVan chitosan derivatives , concentrations
and particle sizes are available for a variety of uses.
Wheel washes can get dirty really fast. Trucks
sprayed with dirty water track dirt onto streets
requiring the use of a street sweeper. Trucks
may be required to drip dry. This costs more
money and lowers productivity.
Before Clear Trax
Dungeness developed Clear Trax 450, a
chitosan-based formulation, specifically for the
management of these high sediment load
conditions. Clear Trax keeps the wheel wash
clean all day.
After Clear Trax
The DE Volumetric Feeder
assembly automatically delivers
Clear Trax when needed and
ensures that just the right amount
is added to keep the water
continuously clean. The feed rate
is adjustable so the operator
determines how much to use.
ChitoVan Residual Test Kit
When is used as directed, no residual chitosan
will be present in the effluent waters. It is
sometimes important to verify that there is no
chitosan in the effluent. Dungeness developed
a quick field test for the qualitative analysis of
chitosan.
Treatability Field Test Kit
Quick and easy tool to test for the flocculation
of turbid water. Determine the treatment
efficacy of ChitoVan™ on any water.
Turbidity, pH and conductivity meters
also available
The EPA now recommends Passive Stormwater Treatment.
Our Kit has everything you need to successfully treat water. You
select the most practical technique(s) based on your site
configuration.
Contents include: applicator lay flat Cam-loc hose, 7 ChitoVan LC
cartridges, adaptor and field guide to take you step-by-step through several
passive treatment techniques.

Through the efforts of environmental awareness,
regulatory agencies and community demand some
progress has been made toward achieving clean water
required for recreation and healthy aquatic life.
However, there is much more work to be done. We are
currently researching and developing new technologies
for drinking water and recreational markets.
