As the need for electricity in major U.S. cities continues to grow, so does the need for generating it in an environmentally friendly way.

Water is a key element in the generation of electricity; used to run turbines, cool components and produce steam. But even water considered to be clean must be treated to remove impurities that could harm the steam generating equipment in the plant. To improve the process, new technologies like Siemens' mobile water purification solutions are focusing on minimizing waste and reducing the amount of water required to operate a plant.

The system not only lowers cost but dramatically decreases emissions and conserves natural resources. In addition, the mobile trailers don't require on-site chemical regeneration or discharge permits, making them better for the environment.
