Harmful gas leakage during sewage treatment process

1. Organic matter releases hydrogen sulfide and methane during the degradation process, while depleting oxygen, and these risks exist throughout the entire process. These gases and various lowland working environments pose a confined space hazard. The last step in the process flow is to perform tertiary treatment, which requires the use of suitable portable gas detectors. There are many brands to choose from, such as BW's GAXT single handheld meter, composite gas alarm MC2-4, Honeywell XP single meter system, Huarui RAE's PGM-1700, PGM-2400, and PGM-62XX

Restricted space: Four types of gases (hydrogen sulfide, oxygen, combustible gas, CO) must be equipped with monitoring standards. In this case, a pump suction detector must be equipped, such as XT-XWHM, PGM-2500, PGM-62XX, etc.

3. Pumping station dry well: confined space: The dry well is located below the ground, and although there should be no sewage or gas present, the wet well may have leakage and oxygen deficiency. Such as single oxygen meters GAXT-X, IMPULSE XP, PGM-1100, PGM-1860, and others. There is no need to install a fixed detection system in a dry well. Ventilation equipment can be used to improve air quality. However, dry wells are confined spaces, and portable detectors should be used to ensure safe entry and operation.
