Compactor Cleans Up in Seattle
In 2004, a team of researchers from Washington state’s King County Wastewater Treatment Division took on the task of cleaning up problems with the discharged screenings at their two treatment plants. The screenings were filled with excessive water and fecal and other organic matter. The local landfill put restrictions on the time and place in which screenings could be unloaded because of the high fecal content. The landfill dug special pits before the screenings could be dumped, then would immediately cover them. The research team was concerned the restrictions might one day impact plant operations. The team analyzed various solutions and decided to test a Screenings Washer Monster at the South Plant in Renton, Wash. The SWM was tested for a month and dramatically improved the cleanliness and odor of the screenings.
