Publication number: 20200406268Abstract: Methods and systems for reducing an average particle size of blackwater solids is disclosed. A vessel is configured to receive a blackwater stream through a one-way inlet. The one-way inlet is configured to allow the blackwater stream into the vessel and prevent backflow. The blackwater stream contains blackwater solids and water. A device in a bottom portion of the vessel is configured to receive the blackwater and comminute the blackwater solids. A recirculating pump is configured to recirculate the blackwater stream under pressure through the device until the average particle size of the blackwater solids is reduced below a size threshold, resulting in a sized blackwater stream.Type: ApplicationFiled: June 28, 2019Publication date: December 31, 2020Applicant: Hall Labs LLCInventors: David Hall, Michael Hall, Cody Rees, Thomas Corie, Nathan Davis

Publication number: 20200406269Abstract: A method and a plant for producing secondary solid fuel (SSF) provide for removing fine and heavy waste from a flow of treated waste and further subdividing the remaining waste into intermediate waste and light waste. Only the fraction of intermediate waste is subjected to removal of chlorinated plastics (PVC). Advantageously, thanks to the fact that only a small fraction of the treated waste is subjected to removal of the chlorinated plastics, high efficiency in the treatment of waste and in the production of SSF is obtained. Preferably, the intermediate waste fraction is also subjected to removal of ferrous metals and non-ferrous metals, such as aluminum.Type: ApplicationFiled: September 4, 2018Publication date: December 31, 2020Inventors: Pietro Paolo Cella Mazzariol, Gian Francesco Galanzino
