Sludge

Sludge

Methane (CH4) gas generated from anaerobic digesters also contains hydrogen sulfide (H2S) resulting from decomposing sludge. The H2S 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 S4000C/T and IR2100 Infrared Point Gas Detector because of high O2. The Model IR5000 is also used for CH4 detection in large waste treatment plants.

De-watering System

Incoming Sludge

Outgoing Sludge to Incinerator

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 S4000T Intelligent Sensors are positioned so that during operation of the compressor any escaping H2S will be detected.

Model S4000T Intelligent Sensors are positioned both sides

of the compressor

Sludge Dewatering

Wet wells and dry wells are confined spaces which can develop a build-up of H2S and CH4. This gas concentration can become explosive and/or toxic to the level of personnel danger. Because personnel are required to service these areas, O2 deficiency monitors are installed to ensure that oxygen levels do not drop below the regulated levels needed to sustain life.

Models HVS4000 / HVS400 and S4000C/T’s can all be used for these applications.

Landfills produce Methane and H2S 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 S4000C Intelligent Sensors to detect the methane gas.

S4000C 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 S4000C Intelligent Sensors are used to monitor leaks in the co-generation building

Selling against the Competition

• Fixed Gas Detector Competitors typically found in the Water & Wastewater Industry are:– ATI– Capital Controls– Foxcroft– Regal– MSA– US Filter

• Advantages of HVS4000 and HVS400 are:– HVS400 is small and compact by design with a 4-20mA signal that can be used as the “front-

end” sensor for a SCADA system directly

– HVS400 2-wire self contained transmitter with sealed electronics is very suitable for corrosive chlorine service

– Calibration prompts can be viewed on the LED window, without the added expense of a transmitter housing with a display

•  

– End-users have reported that the HVS400/4000 is rugged and looks more like an industrial product than competitors… such as “Foxcroft, Capital or Regal”… who more closely resemble “Swimming Pool Type” chlorine detectors

– Most Cl2, SO2, H2S applications do not require a XP rated enclosure, however that’s all many competitors have to offer. The general-purpose enclosure on HVS400 sensors, will keep system cost down

– End-users like the “potted & sealed” HVS400 electronics because corrosive gases cannot access the PC board components

– Galvanic isolation on the HVS4000 allows hot swapping of sensors and remaining sensor life, reduces downtime by providing a “heads-up” on sensor life

– Dual redundant MODBUS RS485 interface provides remote operation of all functions
