INTRODUCTION
 This presentation is designed to communicate the
concepts of an energy and water-saving technology.
 This technology forms the foundation of a class of
equipment that, due to the important efficiencies it
provides, should play a significant role at the vanguard of
energy management programs and activities.
 The goal is to impress upon those working in the field
the value of making these concepts a part of the
everyday considerations that make up energy
management initiatives and programs.

TOPICS OF DISCUSSION
 Water quality has a direct effect on the energy
consumption and efficiency of all industrial, commercial, and
residential water-fed equipment
 Energy-Efficient equipment and appliances allow improved
outcomes
 Energy-Efficiency devices and systems take a very important
next step in obtaining best results and should be part of
Best Practices

WATER QUALITY HAS A DIRECT EFFECT
ON …
THE ENERGY CONSUMPTION AND EFFICIENCY
OF ALLWATER-FED EQUIPMENT
 Example: Boiler & cooling tower blowdown optimization
 Savings and payback period demonstrate reduced
consumption and increased operating efficiency

• Nine potential water and energy conservation opportunities for facilities, identified by
the U.S. DOE
• Boiler blowdown optimization alone can account for as much as 50% of the potential
energy savings
• Since these efficiencies are specifically obtained by means of water treatment, this
measure provides significant evidence of the impact of water quality on energy
consumption

PAYBACK PERIODS
Including only direct energy and water savings, the payback on the
boiler blowdown optimization far exceeds the payback on any other
measure

ENERGY-EFFICIENT EQUIPMENT
 EnergyStar and other efficiency and improvement programs
raise consciousness, achieve positive results
 Rebates and subsidies encourage their use
 But …operating efficiency will still diminish based on water
quality conditions

ENERGY-EFFICIENCY DEVICES & SYSTEMS
 A class of fluid treatment equipment that takes water and
energy conservation to the next level
 Non-chemical, environmentally friendly technology
 Easily retrofitted to existing equipment, easily installed with
new equipment to maintain and improve operating
efficiency
 Helps keep equipment operating to rated levels and
maintain compliance

REAL LIFE
 U.S. Department of Energy:Thickness of scale
accumulation increases energy consumption
by:
 1/32” = 8.5% increase
 1/16” = 12.4% increase
 1/8” = 25.0% increase
 1/4” = 40.0% increase !!
 In energy-intensive industries, the impact can
be significant, easily affecting the bottom line

ENERGY INTENSIVE INDUSTRIES
Some examples:
 Agriculture
 Glass Manufacturing
 Metal Foundries
 Brewing
 Sugar Production
 Food & Drink Canning
 Grain Mill
 Others

APPLIED BENEFITS OF TRIANGULAR
WAVE TECHNOLOGY
 Non-chemical scale reduction and control allows treatment without
creating a new set of problems
 Triangular waveform guarantees effective signal penetration where
other waveforms cannot
 Reduced biofilm, therefore reduced bacteria growth & corrosion
 Improved heat transfer efficiency
 Reduced energy & water consumption
 Extended capital equipment lifecycle, investments protected
 Reduced maintenance, labor
 Reduced operating costs
 Achieves a clean, scale & biofilm-free fluid delivery environment
