Aruba facilities install
UV disinfection systems
W.E.B. Aruba NV, the operator of
the Balashi water treatment plant
on Aruba, installed ten Berson's
InLine ultraviolet (UV) disinfection
systems instead of chorine-based
systems as part of its non-chemical
approach to water treatment. Eight
systems are used to disinfect
drinking water and two are used to
treat greywater prior to discharge.
The Balashi plant houses the
world's second largest desalination
plant, which supplies the semi-arid
island residents with drinking water.
Five Berson UV units are installed
at the Balashi plant, located near
Oranjestad. Following the
desalination process, water passes
through the UV systems before
being transported to seven storage
tanks situated at elevated locations
around the island. The UV units,
which are installed outdoors and
controlled by DGtronic
microprocessors, each disinfect 400
m3 of water per hour, rising to 600
m3/h during peak flow conditions.
No chlorine is used at any stage of
the treatment process.
Project Manager Mr. Ruiz
commented: "Chlorine was
originally considered as an
alternative to UV but was rejected
after concerns over costs and safety.
W.E.B. Aruba also has an anti-
chemical policy."
Two of the seven storage tanks
situated around the island are also
fitted with Berson's InLine UV
systems, providing an additional
disinfection step prior to dis-
tribution. All tanks will eventually
be fitted with UV. One storage tank
in the harbor supplies cruise ships
with UV-treated drinking water.
In addition to disinfecting
drinking water, two Berson UV
systems treat greywater. One unit is
installed at each of the island's two
wastewater treatment plants and
the treated greywater is used to
irrigate the island's two golf courses.
The Dr. Horacio Hospital on the
island also uses UV technology.
"There is a lot of interest in our
UV systems on the island, especially
from businesses wanting to use
greywater for hosing down
buildings," says Berson's customer
service manager Danny van
Kuringen. "It is very dusty on
Aruba, so keeping the outside of
buildings clean is a real concern for
many companies. We have also
recently supplied one of our new
InLine+ UV systems to disinfect
drinking water for the airport."
Berson's compact InLine medium
pressure UV systems use MultiWave
lamps, which emit a wide spectrum
of UV wavelengths with high energy
output, causing the total and
permanent deactivation of
microorganisms. The small size of
the lamps means that they are
positioned perpendicularly to the
flow of liquid, increasing dis-
infection efficiency, and reducing the
overall size of the disinfection unit.
Berson's InLine+ series of UV
water disinfection systems are fully
validated in accordance with the
USEPA UV Disinfection Guidance
Manual. The validation certifies the
use of the systems for the Long
Term 2 Enhanced Surface Water
Treatment Rule released by EPA in
November 2006.
Berson UV supplies a complete
range of UV systems with capacities
between 10 � 10,000 m3/hour,
certified to the newest German
DVGW norm, W294, Part 1, 2 & 3
� the highest standard currently
possible in the world. DVGW is the
acronym for German Technical and
Scientific Association for Gas and
Water, which is the body responsible
for industry self-regulation in the
German water and gas and water
supply industry and its technical
rules are the basis for safety and
reliability.
