The Sanitec Process

1.      Sanitec units are delivered housed in an all-weather steel enclosure. Systems can be installed either inside or outdoors, and require only a standard 480 electric line and standard water hookups for the onboard steam generator. There is no drain required because there is no water emission. Installation generally is complete within two days, and units can be easily relocated to accommodate changing space requirements.


2.      An automated lift/load mechanism eliminates the need to lift heavy bags. Waste is brought to the unit in carts, which are then attached to the Sanitec unit and emptied into the infeed hopper. The loading mechanism can be designed to accept a wide variety of standard cart systems. 




3.  The infeed hopper is sealed and waste is ground into tiny particles by a sophisticated shredding system designed specifically for medical waste. Grinding creates a more even waste stream that can be effectively treated at lower temperatures than competing systems, thereby eliminating the potentially harmful air emissions associated with other units. Shredding reduces the waste volume by 80%, and renders it unrecognizable.  


4. Air from the infeed hopper is drawn by a fan through a series of filters including a High Efficiency Particulate Air (HEPA) filter and a carbon filter to control odors. Air tests performed on the system confirm that no harmful air emissions are released during waste processing.




5. Waste is then picked up by a stainless steel screw conveyor, moistened with steam, and passed by a series of microwave units. Microwave energy is extremely efficient at thermally treating each individual waste particle from the inside out, assuring thorough disinfection. Treatment is verified on a regular basis by challenge testing using spores of bacillus subtilis (var. niger).


6. Treated waste is then transported outside the unit by a secondary screw conveyor and is deposited into a waste compactor or dumpster. At this point, waste is considered safe for disposal in any municipal solid waste program. An optional granulator is available for further waste reduction if
desired.


7.The entire process is controlled by an on-board microprocessor. A highly sophisticated computer program monitors the waste treatment cycle, assuring that all time and temperature parameters required for treatment are met before any waste is discharged. Continuous digital monitoring and a built-in strip chart are included to do real-time recording of the disinfection process.



8. From start to finish, the Sanitec Microwave Disinfection system is designed to provide process and engineering controls that assure complete disinfection and destruction, while minimizing the operator's exposure to risk.
