Volatile Water Pollutants Contribute to Global Air Pollution |
Author : Dr. Frank Eismann
Company : Eismann & Strobe GbR |
There is an enormous lack of information on sources, character and quantity of water-born gas emissions. The environmental significance and economic relevance of these emissions are principally acknowledged but quantitatively unknown. This article highlights some aspects of the evolution and liberation of gaseous compounds from waters, means to analyze and remote emissions, as well as possible strategies for their abatement. |

As populations grow and environmental requirements become more rigid, demand for electricity at treatment plants is expected to grow by approximately 20 percent over the next 15 years, states a Wastewater Management Fact Sheet formulated by the Environmental Protection Agency of the United States.
Siemens Water Technologies' innovative OMNIFLO Interchange Sequencing Batch Reactor (ISBR) system produces a very low sludge yield of 0.05 to 0.25 pounds of biological solids per pound of BOD per day, compared to a typical SBR system, which provides increased flexibility as well as significant power savings.
The Roseburg Urban Sanitary Authority completed a $400,000 upgrade that included a new air blower and air-diffuser system for two wastewater basins. During warmer months, the air-delivery system kick-starts waste-eating organisms into life by pushing more oxygen into wastewater, blowing tiny air bubbles from the bottom of the basins.
