  • Descrição: What's the best way to control volatile organic compounds? At the East Bay Municipal Utility District in Oakland, Calif., a study using a mathematical model indicated that an integrated approach, using simple covers, can help treatment plants meet air quality standards for VOCs and other air toxics. Process modifications and the installation of covers can achieve high performance efficiency; but for overall effectiveness cost considerations must be evaluated as well. As mandated by the 1990 Clean Air Act Amendments, and by existing and pending state and local regulations, publicly owned treatment works (POTWs) in the U.S. will be required to implement maximum and best available control technologies to meet new air quality or health risks standards. While source control is typically the key air emissions compliance strategy at a POTW, an alternative strategy is an integrated approach, taking into account other air emissions control options as well, such as process modifications, passive vapor phase control measures (covers), biodegradation, wastewater chemical treatment, or air stripping. Process modifications and the installation of covers could easily complement EBMUD's existing emissions control systems and yet offer effective, low cost alternatives for meeting the anticipated new air quality and health risk requirements.
