Pollution Engineering - October 2008 - (Page 37) CATCHING FOR CLEAN Windmill-driven aeration is an affo ndmill-driven aeration o affordable, self-sustaining ordable, d technology that is good for the water supply and environment. By ED SULLIVAN F ighting fire with fire is one thing; fighting contaminants in ponds and lakes with harsh chemicals can be dangerous, expensive and ineffective. Yet, the alternative, aeration equipment, can be too expensive to be cost-effective. Some communities are finding that they can harness free energy to power such aeration systems, and thus get the best of all worlds. Managers and owners of ponds, lakes and reservoirs often use aeration instead of or in addition to chemical treatments such as copper sulfate to eliminate biological and chemical pollutants. Windmill-driven aeration is widely used in agricultural and recreational bodies of water due to its low capital costs. With energy prices skyrocketing, such systems are now becoming increasingly popular in municipal applications such as water storage, golf courses and public parks. Windmill-driven aeration is widely used in agricultural and recreational bodies of water due to its low capital cost and energy freedom. They are becoming increasingly popular in municipal applications such as water storage, gold courses and public parks. Aerating the Attica reservoir In Attica, N.Y., the water department began implementing wind power almost nine years ago. The city’s 8.5-acre reservoir, which holds approximately 50 million gallons of water, was contaminated with an influx of manganese and iron during the spring and autumn water turnovers. “The condition was worst during the fall months when turnover would stir up iron and manganese that naturally occur in the reservoir,” said Brian Krawczyk, chief operator at the plant. “But when there was high manganese and iron content and we treated the water with chlorine, we would get red water problems and constant turbidity.” Krawczyk noted the water treatment plant had used copper sulfate as an algaecide 37 OCTOBER2008 www.pollutionengineering.com http://www.pollutionengineering.com
