Biological treatment in wastewater treatment Control and maintenance of the biological stage
Biological wastewater 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.
Discover secure network components, control technology, and energy measuring devices for efficient plant operation. Flexible transmission processes are available for various fields of applications.
Optimum wastewater cleaning process
Precise control of process values, such as the oxygen content in the aeration tank, is an essential requirement when it comes to the optimum treatment process for wastewater. Phoenix Contact develops special software libraries for controlling and monitoring wastewater technology in the biological treatment process. Measurement and control technology is integrated in a short time 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.
Our solutions for your processes
Easy integration of industry-typical equipment
Programmed function blocks from the Water Functions library simplify the manufacturer-independent connection of equipment 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 controller from the PLCnext Control family and transmitted to the control system. The modular design enables the plant to be extended at any time.
Wireless data transmission from the aeration tank to the control room
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.
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.
Wireless communication allows you to transmit the process data wirelessly
