A novel process was developed for the biorefining of floatable wastewater scum and other waste oils from water treatment facilities into biodiesel and other value-added bio-products. To test the scalability and commercial potential of the technology, a 7000 l/year pilot-scale system was designed and built. Scum from a wastewater treatment facility, located in St. Paul, Mn, was collected and converted into methyl esters (biodiesel) according to the process chemistry. All of the incoming and outgoing process streams were sampled, tested, weighed and recorded to calculate both the process efficiency and product quality. Data from the pilot-scale system operation was compared to laboratory results and the theoretically expected values for each individual unit operation. The biodiesel was tested using a third party laboratory and confirmed it met all of the US EPA's test requirements for commercial-grade biodiesel.
开发了一种新工艺,用于将浮渣和其他来自水处理设施的废油从可浮性污水中提炼出来,转化为生物柴油和其他增值生物制品。为了测试该技术的可扩展性和商业潜力,设计并建造了一个 7000 升/年的中试规模系统。收集了明尼苏达州圣保罗市一家污水处理厂的浮渣,并根据工艺化学将其转化为甲酯(生物柴油)。对所有进出过程流进行了采样、测试、称重和记录,以计算工艺效率和产品质量。将中试系统运行的数据与实验室结果以及每个单独单元操作的理论预期值进行了比较。第三方实验室对生物柴油进行了测试,结果表明其符合美国环保署对商用级生物柴油的所有测试要求。
