| Popis: | Volatile organic compounds (VOCs), present in the exhaust gas from the biosolids drying system, are required to be destroyed prior to the exhaust gas being released to the ambient air. Biogas, a byproduct of the waste sludge treatment process, can fire the dryer instead of natural gas, a common source of energy. Biogas' components, typically a combination of methane, carbon dioxide, and other traces gases, and the destruction of VOCs released from biosolids drying will depend on the type of waste sludge being treated at the plant. Therefore, biogas utilization can raise concerns as to whether using biogas adds to the VOC emissions that could subject the plant to hazardous air pollutant (HAP) regulations. Research was conducted at an industrial scale to study potential emission differences from the final regenerative thermal oxidizer (RTO) of the dryer exhaust gases when the biosolids drying system was fueled by natural gas and biogas at the Morris Forman Water Quality Treatment Center (MFWQTC) in... |
