Biological treatment

Biological treatment

The heart of the wastewater treatment plant

Using solutions from Phoenix Contact, you can ensure an optimum treatment process for wastewater.

Biological treatment is both the core and also the largest energy consumer in the cleaning process of a wastewater treatment plant. Key process variables have to be controlled flexibly and precisely to ensure optimum cleaning performance.

Phoenix Contact develops special function block libraries for wastewater technology. Devices are integrated quickly and connected in an energy-efficient manner. Energy measuring devices, secure network components, and modular and open control technology guarantee secure and efficient plant operation.

Your advantages

  • Reliable communication with communication technology from the measurement point all the way to the control room
  • A high level of IT security with certificate-driven communication
  • Flexible monitoring procedures for various fields of application such as cable-bound solutions or GPRS, DSL, UMTS, LTE, Bluetooth, and LoRaWAN

Easy integration of industry-typical equipment

Process data acquisition and transmission  

Easy connection of operating data through mobile end devices

Programmed function blocks from the Water Functions library simplify the manufacturer-independent connection of devices such as measuring devices and frequency converters in pumps and blowers. All key process data such as speeds of rotation, power consumption, and fill levels are acquired reliably using a PLCnext Control device and transmitted to the control system. The modular design allows the plant to be extended at any time.

Wireless process data transmission

Wireless communication via WLAN

Connection to the control room and access to the different parts of the plant is realized in various ways with modern technology. However, the costs for retrofitting cables are often high, in particular in modernization projects.
Wireless transmission procedures are a flexible and cost-effective alternative for communicating process data from the field to the control room.

Wireless data transmission from the aeration tank to the control room

Modern wireless communication provides you with the required flexibility for every application.
Process data is exchanged between individual areas, such as the dosing station and aeration tank, via PROFINET and WLAN. All relevant process values are safely transmitted to the control room.
