Digester Gas Monitoring Ground Flare S 4000 CH Gas Detector Sludge Digester Tank Gas Flowmeter Methane (CH 4) gas generated from anaerobic digesters also contains hydrogen sulfide (H 2 S) resulting from decomposing sludge. The H 2 S gas is usually removed. Methane gas is used to fuel compressors, boilers and engines. Any unused gas is then flared off to the atmosphere. Applications exist for Models S 4000 CH/TH and IR 2100 Infrared Point Gas Detector because of high O 2. The Model IR 5000 is also used for CH 4 detection in large waste treatment plants.

Sludge Dewatering Outgoing Sludge to Incinerator De-watering System Model S 4000 TH Intelligent Sensors are positioned both sides of the compressor Incoming Sludge Incoming sludge from waste treatment facilities contains hydrogen sulfide and methane gas. The sludge is transported through a spiral conveyor into the de-watering system where the water is removed. The outgoing conveyor transports the remaining solids to an incinerator. Model S 4000 TH Intelligent Sensors are positioned so that during operation of the compressor any escaping H 2 S will be detected.

Wet/Dry Wells & Lift Stations S 4000 CH/TH and TS 4000 Manhole Sewer or Vault Wet wells and dry wells are confined spaces which can develop a build-up of H 2 S and CH 4. This gas concentration can become explosive and/or toxic to the level of personnel danger. Because personnel are required to service these areas, O 2 deficiency monitors are installed to ensure that oxygen levels do not drop below the regulated levels needed to sustain life. Models TS 420/TS 4000 H, S 4000 CH/TH’s can all be used for these applications.

Landfill Vapor Recovery Scrubber S 4000 CH Gas Detector Control Valve Gas Compressor Landfill Gas Well Gas Pipeline Landfills produce Methane and H 2 S gas generated from decomposing materials. The recovered methane is used to fuel compressors, engines and co-generation plants. These facilities provide an excellent opportunity for Model S 4000 CH Intelligent Sensors to detect the methane gas.

Cogeneration S 4000 CH Gas Detector Many sewage treatment facilities use Methane generated from digesters to power electrical generating plants. This power is used to run the facilities as a supplement to purchased power from utility companies. Model S 4000 CH Intelligent Sensors are used to monitor leaks in the cogeneration building.
