Google Data Centers Using Recycled Water for Cooling


Google has made an eco-friendly data center in Georgia (USA). The U.S. Company Google Inc., which has data centers around the world, has taken a big step with the use of recycled water system that cools its facilities, which is less harmful to the environment.

The data centers require a large amount of electricity and need constant cooling to ensure operation. Some methods employ cooling electricity using waste heat for cooling appliances. Although this is an efficient way to achieve cooling systems, pollution produced is too high. So some companies are experimenting with new formulas less aggressive cooling with the surroundings.

Google has reached an agreement with the leaders of the sewerage system in the area to create this system and have the key to use 100% recycled water in their data center. The system is simple: the plant area that cleans water used and forwards it to the Chattahoochee River helped build a small treatment plant west of the center of Google, who lures the search facilities of up to 30% of treated water.

In the ecological center of Google in Georgia, the cooling system is based on evaporation but unlike other data centers that use this model they use recycled water. The wastewater comes after passing through a water treatment plant to the data center, there to cool the systems and is expelled after serving their function, again outside. Their return to the water cycle occurs as steam, after passing through cooling towers.

The water that has evaporated during the cooling process is sent to a wastewater treatment plant facilities located in the data center. There is again treated water to disinfect, remove solid minerals and send back to the river.

According to organizers of Google, its data centers use half the energy they depend usual free cooling chillers instead of mechanical.

A data center can use thousands of gallons of water a day. When Google began using its data center in Georgia in 2007, the drinking water was used for cooling. “At Google we have been working for years in order to maximize the efficiency of our servers and our data center designs, in order to minimize the footprint of energy consumed by our data centers.” says Joe Kava, director of construction and operations.

“We place our data centers in places where we can maximize the natural cooling and minimize the amount of what they call ‘mechanical cooling’. We do not want to take away drinking water to communities in which we stand, and we use recycled water, “says Kava.

Technology companies increasingly need more energy, so you need to build more data centers. Now many large companies have been pressed to the growing demand from users to reduce pollution and energy use. A good example of this is Facebook, which has recently been criticized for saying that they would use the services of Pacific Power, whose energy comes from carbon emissions, one of the ways to get more dirty electricity there.

The trend for large companies to use greener ways of working is increasing, so probably begin to emerge more innovative ideas to leverage resources.
