Reducing the use of water inside data centres

Silver Bullet Corp. of Denver, Colo., is calls itself a non-traditional water treatment company. The company is working with in the technology space transforming water treatment processes for data centres. Silver Bullet technology creates a natural non-toxic biocide when injected in water, killing all bacteria, removing scale and preventing corrosion.

With this process, data centres have reduced the chemicals used to treat cooling tower water. The process results in saving millions of gallons of water and tens of thousands of kilowatt hours of electricity, decreasing overall operating costs, the company said.

More than half of a data centre building’s water use is from cooling towers, which provide cooled water for air-conditioning, manufacturing, and electric-power generation. A typical 15-megawatt data centre could use up to 360,000 gallons of water a day to keep servers and equipment cool enough to operate effectively. By targeting this component of building infrastructure with Silver Bullet’s water treatment system, savings can be seen in electricity, water, labour and maintenance.

Robert Hanfling, the executive chairman of Silver Bullet, said the treatment system is a unique, proprietary electro-chemical water treatment system that disinfects and conditions cooling tower water to virtually eliminate microorganisms and scale formation.

“If Silver Bullet’s technology were installed on 20,000 cooling towers, just one-per cent of the commercial cooling towers in the United States, water savings could top 10 billion gallons a year and reduce electricity consumption by more than 1,200 megawatts of power,” Hanfling added.
