One-Way Macerator

One-Way Macerator Datasheet

The Uson One-Way Macerator system is designed for hygienic collection and treatment of food waste in compliance with IMO Marpol 73/78 Annex V, US Coast Guard and other relevant regulations and standards.

Food waste is ground by local macerator(s) and shredder in the galley and collected by vacuum to a special holding tank, which is designed for food waste. This makes it possible to run the system when the vessel is operating within an area where discharge is prohibited.

The system safely handles food waste and is easy to install, with a low water consumption, small pipe diameter and flexible pipe routing. As it is suitable to retrofit onboard existing vessels or new builds, the macerator is guaranteed to avoid any blockage of food waste in the piping system.

Food waste is not defined as ‘sewage’ and should not be mixed with either black water or grey water. Food discharged to a sewage treatment plant will contribute to increased levels of biological oxygen demand (BOD), total suspended solids (TSS), grease and oil.

The GPS Discharge Control system ensures that food waste is discharged into sea only when allowed according to IMO Marpol 73/78 Annex V, MEPC 62, ISO 21070, local rules and regulations. Further, the system shall automatically empty the food waste tank prior to entering a restricted area.

All discharged of the food waste tank shall be logged electronically in the system with the following parameters: date and time, Discharge volume, GPS position.

The information shall be logged for two years in compliance with the requirements for Garbage Record Book.
