How the SSM Works

The SSM is an On-Site and Simple Process

An operator loads infectious medical waste into the processing chamber through a 24" diameter hatch opening. Once loaded, the operator closes the hatch and engages the "Start" button. (Unless the hatch is closed and locked, the system will not operate.) From this point forward, and until the process is complete, the operator has no additional interface with the equipment.

Steam is injected into the process tank, followed by 250°F (121°C) superheated water. After a brief soak, the pump grinder is activated and the material is drawn through a proprietary cutter and the impeller of the pump where it is cut again. Material is returned to the process tank where it continues to be cut into smaller and smaller pieces and re-circulated through the system.

After several minutes of cutting, formal sterilization is initiated; temperature of the waste stream is held at 272°F for six minutes. Both a real time hard copy and a digital record are generated to verify sterilization. At the end of the sterilization cycle, cold water is injected into the vessel to cool the material.

Cooled, sterilized material is then discharged into a filter-separator system where solids are separated from the liquids. Liquids are discharged into the sanitary sewer. Solids, which have been reduced in volume by 90%, are captured, dewatered, and discarded as ordinary trash placed automatically in a cart. The operator is then ready to load red bags for the next 30 minute cycle.
