Abstract
A control system for regulating the decontamination of waste in a reaction chamber is provided. The control system monitors the chamber temperature and disinfectant concentration. Using the disinfectant concentration, the control system then calculates the minimum temperature required to maintain a specified level of decontamination. This minimum temperature is then compared to the actual temperature by the control system. If the actual temperature is below the minimum, the control system operates a heater to heat the reaction chamber. Additional temperature control can also be provided by the control system. If desired, the control system compares the actual chamber temperature to an ideal operating temperature. If the actual temperature exceeds the ideal temperature, the system cools the chamber by pumping in additional low temperature disinfectant. In this manner, the additional disinfectant maintains the level of decontamination as the chamber temperature decreases.
