Message: Enviro-Tower: Saving Water And Electricity Problem There’s a high demand for A/C in large buildings. That requires cooling towers, which are severe water polluters and greedy energy users. • Cooling towers across North America use 230 billion kwh of energy • Cooling towers flush out 635 billion gallons of water per year Water cooling towers perched atop large buildings are the biggest sources of toxic discharges that end up in municipal sewer systems. This past summer, a small outbreak of Legionnaire’s disease was linked to emitted bacteria from cooling towers in downtown Hamilton, Ontario. Legionnaire’s disease is a potentially serious illness caused by airborne legionella bacteria, which are commonly found in cooling towers. Up until recently, a chemical cocktail that includes hydrazine, polyoxypropylene, specialty acids, and biocides was the only weapon that systematically combated microbiological contaminations like legionella bacteria. It was also the only defense against scaling, fouling and corrosion in cooling towers. Solution EnviroTowerTM uses electrostatic physical water conditioning technology to keep water cooling towers running smoothly without the use of chemicals. It also uses 25 per cent less energy than other systems and reduces operating costs by up to 30 per cent. The EnviroTowerTM system includes a physical water conditioner, which eliminates scale and inhibits fouling and corrosion, a separator that captures and discharges particles created by the conditioner, and a mineralator that adds suppressants to further control corrosion. The Embassy Suites Hotel overlooks on of the largest sources of hydro power on earth - Niagara Falls. EnviroTowerTM was installed in its cooling towers to eliminate the scale that had built up over just six months of use. After the first cooling season with EnviroTowerTM, there was no visible scale or fouling. The technology is sprouting on other rooftops in Canada, including the TSX building. The company recently added Zenon Environmental whiz Rafael Simon to its board. Potential If all cooling towers across North America were updated with EnviroTowerTM, it would save 160 billion gallons of water a year, and 57 billion kwh—roughly equivalent to the power used by all the homes in Ontario - would be returned to the grid. www.corporateknightsforum.com
