Building Sustainability Challenges Water Consumption
There are over 4.9 million
commercial buildings in the
U.S.
Over 10 billion gallons
of water are used per day in
U.S. commercial buildings
A typical office building uses
33% of total water demand for
cooling (source: US Energy Information
Administration, 2006)
End Uses
of Water In
Office
Buildings
JUST THE FACTS
4
Why Do Facility Owners Treat Water?
Extend the operational life of expensive cooling equipment
Ensure that cooling equipment runs efficiently
Prevent the spread of disease from pathogens
Today over 99% of building cooling
water is treated with chemicals

Biocides and corrosion
inhibitors have a negative
effect on the environment
and human health
Difficult administration
and balancing of
multiple chemicals
throughout lifecycle
Chemical discharge into
the environment via water
discharge, air emissions,
spills and drift
Chemical handling
translates to
increased risk for

The Dolphin WaterCare
Solution
Dolphin WaterCare: Proven
Simplicity of design
Ease of installation
Reliable operation
Low maintenance
Low-energy use
11
Thousands of installations over more than a decade
• Precipitation is favored around the “activated” suspended particles – system surfaces remain free from scale
The Signal Generator in communication with the Treatment Module imparts high frequency pulsed
electromagnetic fields into flowing water.
• Pulsed electromagnetic fields “activate” suspended particles readily available in the water flow

Scale Prevention and Corrosion & Biological Control
Untreated:
Scale formation on
equipment surfaces
Dolphin Treatment:
Particle formation in
cooling water
Electroporation:
Pulse damages bacteria
membrane inhibiting
reproduction
Pulse power technology creates an induced, time-varying, electro-magnetic field which
provides traditional water treatment benefits – in an environmentally responsible manner
