Incineration/Odor Control+Methane Recovery—Sludge Treatment

Sewage sludge in waste water treatment
Sewage sludge in waste water treatment

Methane is a by-product of recovered sewage sludge in waste water treatment. Methane is highly flammable, toxic if inhaled or consumed, and can be extremely dangerous if not handled properly. Methane is odorless, while other resulting gases associated with the treatment of raw sewage are highly explosive, such as hydrogen sulfide. Hydrogen sulfide produces an overpowering odor.  Pepperl+Fuchs has a wide range of intrinsically safe solutions for explosive gases. 



  • Flexibility
    Pepperl+Fuchs has several technology solutions for waste water facilities that range from point-to-point and multiplexed HART and Fieldbus solutions. Today, thanks to the Field Barrier, you can directly connect up to 12 PROFIBUS PA or FOUNDATION fieldbus-H1 field devices or a Segment Protector in Division 2 hazardous areas. Each FieldBarrier has 4 IS connections and can be cascaded together with up to 4 FieldBarriers. The four outputs of the FieldBarrier deliver 40 mA and thus allow the connection of many more intrinsically safe field devices. The need for live work on the passive wiring of trunk and fieldbus distribution modules is extremely unlikely; these can be installed using the explosion proof method.
  • Reduced costs- freedom of choice
    Interface products provides a complete solution for water filtration systems that connect your instruments to a controller. FieldConnex has the right connection for you. Spur lines are connected to the trunk through Segment Protectors and FieldBarriers. FieldConnex enables you to design a topology to optimally satisfy your specific application for hazardous or nonhazardous protection. In all configurations, the High Power Trunk concept is a new approach to solving hazardous as well as general-purpose area fieldbus applications. The High Power Trunk does not limit the energy on the fieldbus trunk cable; rather, the energy on the spur connection to the instrument is limited. The Advanced Diagnostic Module (ADM) monitors the segment health and evaluates the communication signal from host to field instrument. This reduces commissioning time and long-term monitoring. This topology is compatible with FOUNDATION Fieldbus and Profibus thus giving you the flexibility to choose whatever technology makes sense.

Water Treatment facilities monitor and control miles of distributed instrumentation and processes. Many pieces of equipment are supplied from different vendors. Typically they are skid mounted with different technologies. You can now seamlessly integrate this hardware into your system with the best technology products. Pepperl+Fuchs’ protection functionalities help to ensure efficient plant operation with high availability over many years of operation. We don’t require you to fit our equipment technology; our equipment fits to your plant technology.
