los Centro de control de la contaminación de London Greenway ("Greenway" para abreviar) es la principal instalación de tratamiento de aguas residuales de la ciudad de London, Ontario. Greenway es una planta de lodos activados que también recibe lodos líquidos traídos en camiones de las otras cinco plantas de aguas residuales de la ciudad.
Greenway deshidrata los lodos y depende de un incinerador de lecho fluido. En 2008, el incinerador requirió el cierre para una revisión importante que duraría más de tres meses. Los departamentos de Aguas Residuales y Residuos Sólidos de la ciudad son entidades independientes y se les exige que se cobren entre sí por los servicios prestados. Después de determinar que un cierre prolongado del incinerador tendría un costo prohibitivo, el Departamento de Aguas Residuales buscó alternativas.
Schwing Bioset bombas de pistón were previously installed at the Greenway plant to feed the dewatered sludge to the incinerator, so plant personnel were knowledgeable about Schwing Bioset capabilities. The Proceso Bioset was proposed to treat the dewatered sludge to beneficially reuse the biosolids as landfill cover. Representatives from the Wastewater and Solid Waste departments visited Bioset installations in Florida to observe the process and it was determined the end product would be acceptable as landfill cover at a preferable cost.
A change order was issued to the incinerator rehabilitation contractor to install the Bioset process equipment as a back-up sludge treatment train to the incinerator. The component equipment permits flexibility in the layout design that allowed the plant to use distinct idle spaces so that no new structures were needed to accommodate the installation.
The plant processed 25,000 metric tons of Bioset product between August and December 2008 while incinerator rehabilitation work was completed. The city has since returned to incinerating the biosolids, but maintains the Bioset equipment as a back-up for annual shut-down/rehabilitation work.
