Sludge treatment

Sludge treatment

Efficient and safe

Implement energy-optimized and reliable sludge treatment – using solutions from Phoenix Contact.

The diverse processes in sludge treatment, such as sludge digestion, thickening, and drying, are constantly being further developed. The demands on a reliable and transparent sewage sludge drying process in particular are increasing in many regions.

Phoenix Contact provides a broad range of solutions to guarantee energy-efficient operation in all processes. From acquiring the energy data all the way to storing operational data and evaluating it in the control room.

Your advantages

  • Reduced time and effort for the visualization of actuators by using PLCnext Engineer
  • Tailored reporting, thanks to flexible data acquisition and evaluation
  • Safety concepts for wastewater applications with integrated technology such as PROFIsafe

Actuator control and visualization

Measured value acquisition for the wastewater intake  

Acquire, store, and archive measured values

With ready-to-use software function blocks, the time and effort for controlling the frequency converters in screw conveyors and pumps in a return sludge pumping station is reduced. The plant can be visualized easily with the free-of-charge PLCnext Engineer software tool. It includes ready-made visualization symbols for actuators such as motors, pumps, and ventilators.

Efficient sewage sludge drying and cleaning

Energy data acquisition  

Energy-efficient control of pumps and stirrers

Phoenix Contact current measuring devices are used to make sewage sludge applications cost-effective. In addition, other relevant measured values are recorded, transmitted, and evaluated in the control room. Information on the efficiency of the process is transmitted through common interfaces such as Modbus, PROFIBUS, and PROFINET.

Safe digestion tower monitoring

Digestion tower  

Reliable measured value monitoring in the sewage sludge drying process

Reliable temperature and pressure monitoring is required for the optimum aerobic degradation of sewage sludge in the digestion tower. With measuring transducers with ATEX approval, measured values are transmitted directly to the programmable logic controller. Intrinsically safe I/O modules facilitate the efficient control of actuators. Sensors are easily integrated through protocol converters and the HART protocol.

Safety concept for centrifuges

PROFIsafe devices are managed centrally by a higher-level safe controller. It is therefore possible to implement safe groups or safe individual shutdowns. In the event of an overspeed or the actuation of an emergency stop control device, the PROFIsafe controller triggers disconnection via the PROFIsafe devices. The centrifuge drives and also linked units such as sludge pumps are brought to a stop.
