Solid wastes in hospitals contain a lot of infectious materials and are the source of many different pollutions. For this reason they are usually burned in the hospitals's incinerators. These incinerators should be designed by considering the quantity and quality of solid wastes and their particular contents. The incinerator should be used in such a way that the content of the emission from their chimney not exceed the local standards of pollution level. In the hospital's sanitary program consideration should be given to the following important points:
- Hiring of knowledgeable and devoted personnel
for running the incinerator.
-. Controlling the engineering aspects of incinerator
and supervisiny it carefully and continously its work.
-. Preparation and utilization of the necessary devices for filtration of gases emitted from the incinerator.
Noawadays there are a lot of incinerators which have left unused and as a scrap in some cotainer of the
hospitals. The main reason for this situation is the lack of carefully organized running program and some particular technical difficulties. Therefore in this
article attention has been given to the maintenance and repair problems with the lack of effective management. There are few technical devices, which can be easily installed in the way of emission on chimney. These devices have been introduced and their
effectiveness on control of gases and particulates of
emission have been mentioned. The filteration quality of the devices is varied between 85 to 95 percent, according to their design technology. By trying practically some of these devices one can select the best of them for specific Iranian Solid Wastes. Considering the quantity of emitted gases from
chimney and comparing it with the special standard of incinerators, it has been mentioned that the filteration of particulates in the range of 99 to 99.5 percent and of HCl up to 95 percent is acceptable. These can be achieved by utilizing the above mentioned filteration devices.
