Abstract: 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.

Abstract: Methods and systems for modifying ambient sound waves passing through a wall are disclosed. The wall has a first side and a second side with a cavity therebetween. A sound producing device is situated between the first side and the second side and is configured to produce interfering sound waves in the cavity such that the sound waves passing through the wall are reduced, masked, or reduced and masked.
