Water/Wastewater Treatment
Wastewater treatment facilities are located in every community and region
of the country. The process of treating the wastewater requires the plant to
utilizes a range of toxic and dangerous gases and the treatment process also produces toxic and combustible
gases. In addition,
there are many enclosed spaces in a wastewater treatment plant where toxic gases can build up or non-toxic
gases can deplete the oxygen making it dangerous to plant personnel.
Portable monitors can only protect the individual wearing the monitor and are not capable of protecting the entire plant or to protect areas where personnel are not present. Fixed gas detection systems are necessary for these areas.
The Sentry Gas Detection System, Analog gas detectors and gas alarm monitors all have their place in this industry depending upon the scope of the potential hazard.
Areas with potential hazardous levels of gases include:
- Pumping station -- Combustible gas, oxygen, hydrogen sulfide
- Influent and barscreen room -- Combustible gas, oxygen
- Barscreen and conveyor room -- Combustible gas
- Barscreen container and grit screen room -- Combustible gas
- Clarifier (with cover) -- Oxygen, hydrogen sulfide
- Primary wet well -- Combustible gas, oxygen, hydrogen sulfide
- Grit chamber and wet well -- Combustible gas, oxygen, hydrogen sulfide
- Sludge distribution chamber -- Combustible gas, oxygen, hydrogen sulfide
- Basement - generator area -- Combustible gas
- Digester - basement -- Combustible gas, hydrogen sulfide
- Digester - first floor -- Combustible gas, hydrogen sulfide
- Filtration room -- Hydrogen sulfide
- Odor removal equipment -- Hydrogen sulfide
- Furnace room -- Combustible gas, carbon monoxide
The FieldServer Gateway provides the interface necessary for safety devices, process equipment and facility controls so that these various individual systems and devices can communicate to the distributed control systems found in such plants operating on DH+, Profibus, Modbus, ControlNet or EtherNet/IP.
