Abstract
Material to be treated, such as medical waste is placed in a chamber (3) which is then partially evacuated by a vacuum pump (37) via a mixing chamber (35) and a non-return valve (31). One or more pulses of ozone are applied to the chamber (3) from an ozone generator (22) via a non-return valve (26). After each pulse, ozone is drawn from the chamber (3) by the vacuum pump (37) and mixed with steam or water vapour supplied by a source (34). The chamber (3) is then flushed with steam or water vapour from a source (22) and irradiated by a source (13) of ultraviolet, infrared or microwave radiation.
