  • Granular litter cleaning apparatus and process
    Patent number: 11697126
    Abstract: A granular litter cleaning apparatus comprises a separation system having a separation tank adapted to receive a mixture of granules and plastic litter, and water therein, the separation tank having a top opening, and a closeable bottom outlet, and at least one water inlet for feeding water to the separation tank. A collect subsystem is for conveying a mixture of granules and plastic litter to the separation tank. A pump system is in fluid communication with the water inlet. The pump system is operated to raise a level of water in the separation tank to skim water with plastic litter out through the top opening of the separation tank. The closeable bottom outlet is openable to empty the separation tank from granules decanted in a bottom of the separation tank. A process for separating plastic litter from granules is also provided.
