Relaxing in a clean homeSewage

Sewage leaks can be a major health hazard to any individual occupying a structure. The pathogens left behind from a sewage spill include Salmonellae, Shigellae, enteric viruses, E. coli, Hookworm eggs, and Roundworm eggs.

The AZEX HEAT process can be used to kill many of the pathogens found in sewage. The table below shows the pathogen and the lethal temperatures to kill them.

Pathogen Temperature Time
Enteric viruses 140°F Rapidly
Salmonellae 140°F 20 Minutes
Shigellae 131°F 60 Minutes
E. coli 140°F Rapidly
Entamoeba hystolytica cysts 122°F 5 Minutes
Hookworm eggs 122°F 5 Minutes
Roundworm eggs 131°F 120 Minutes

Destroy Bacteria with Heat

Common indicators of the presence of these organisms in sewage are the presence of Escherichia coli (E. coli) and the fecal streptococcus group.

E. coli are aerobic bacteria that can be found in the feces, colon, or gut of warm-blooded animals. It is contracted by coming into contact with objects or substances that have come been contaminated by the fecal material of man or animals. The fecal material can come from the runoff of a dead animal upstream, cattle, spills, or raw sewage overflow. There have also been cases of airborne transmission reported.

The AZEX HEAT process has proven to be effective in disinfecting the contaminants present in raw sewage. Not only will the process render bacteria non-viable, but it will also minimize the disposal costs, because the waste does not need to be disposed of as a biohazard.

Utilizing the AZEX HEAT process the temperature of the room will be raised from 150°F to 180°F, depending on the bacteria and viruses present. 100% effectiveness has been shown in post-remediation sampling.

Remove Odors with Heat

Hotels and motels need dust mite extermination even more than other businesses or households.

Many of the indoor air quality issues the AZEX HEAT process is used to solve are accompanied by odors. Odors are caused by the organic deterioration of a substance. This substance can be VOCs, Formaldehyde, bacteria, molds, etc.

The AZEX Heat process can easily reduce many odors caused by common indoor contaminants. By increasing the temperature of the structure we can increase the vapor pressure causing the source to off-gas more quickly. The process will then remove the gas from the structure. The result is a cleaner indoor environment. Professional Papers
