  • Patent number: 7980257
    Abstract: Provided is a parts washer that includes a multi-tiered basin, a cleaning fluid and a biological component, living within the fluid, that breaks down organic waste. The multi-tiered basin includes a sink member with a false bottom, and a support grid and filter are interposed between the false bottom and a bottom panel of the sink member. The false bottom, support grid, and filter are readily removable from the sink member. The tank is partially filled with the cleaning fluid and a pump and conduit assembly direct a flow of the cleaning fluid to the basin. The cleaning fluid discharged into the basin flows through a drain hole in the false bottom, through the filter and support grid, and then through a drain hole in the bottom panel of the sink member back into the tank for reuse. The cleaning fluid includes, at least, a surfactant that functions to remove organic waste from the parts being washed.

  • Patent number: 6571810
    Abstract: Provided is a “parts washer” that includes a fluid that performs a cleaning function and maintains the viability of microorganisms in the fluid which biodegrade organic material in contact with a biological component, the parts. “Parts” include objects befouled with organic material and/or particulate matter. The cleaning fluid includes a surfactant that functions to separate organic waste from the parts being washed. A multi-tiered basin houses the cleaning fluid and the biological component living within the fluid that breaks down organic wastes produced by the cleaning fluid. The multi-tiered basin which forms the mechanical component of the washer, includes a sink member with a false bottom, and a support grid and filter to support microorganisms interposed between the false bottom and a bottom panel of the sink member.
