Nalco 3D TRASAR® Technology for Cooling Water combines
innovative chemistry with state-of-the-art monitoring and control
hardware and software to optimize the 5-star hotel's cooling
system, allowing reuse of wastewater, cutting fresh water use by 16
million gallons per year. Improved cooling system performance – by
preventing scale buildup, corrosion and microbiological fouling –
also prolongs equipment life and conserves 600,000 kWh of energy,
avoiding more than 400 tons of greenhouse gas emissions as
well.
This success in Mumbai is an
example of a major program launched by Marriott with Nalco to
deliver 450 million gallons in water savings over a three-year
period by using Nalco monitoring equipment to optimize the water
treatment in chillers and cooling towers in Marriott full-service
hotels worldwide. The program is one of a number of steps being
taken by Marriott to further reduce energy and water consumption by
25 percent per available room by 2017.
The Nalco 3D TRASAR system works proactively to prevent the
formation of scale, corrosion, and equipment fouling or malfunction
before it occurs. A fluorescent particle tagged to water treatment
chemicals allows the system to continuously monitor and adjust
chemical consumption for optimal use, reducing overall chemical use
and preventing system fouling.
