Pneumatic discharge controle for throttling to 570 l/s

City of Solothurn (CH), flood relief Postplatz
Topics
Land

The old weir in the spillway at the Postplatz in Solothurn served for many years, but now had to make way for a system that meets the requirements of modern sewer network operation. The water flows from the 1.7m inlet canal via the opening in the ground (jump weir) into the 600-metre canal, which is about 1m lower, in the direction of the sewage treatment plant. The outflow is now measured and throttled directly after the opening in the lower-lying 600-metre canal in a shaft built especially for the measuring and throttling unit.

Terms of reference

  • Precise flow measurement in dry and rainy weather from 1 l/s.
  • Precise limitation of the flow rate.
  • Variable throttle quantity for later sewer network management.
  • Connection to the distributed control system of the local wastewater treatment plant via mobile communication.

STEBAnet data communication systems
Secure and volume-reduced data transmission on the Internet and in networks.

STEBAnet Mobile and Fixed Network Telecontrol

Networking and remote control of automation systems STEBAnet mobile, fixed and leased lines are data communication systems for decentralized control systems. Measurement data and control information are recorded on site for backup purposes and cyclically sent in packets or compressed form to the database of the central process control system. STEBAnet communicates in a way that preserves data volume and establishes connections only when needed, for example when a user at the process control system is viewing live data.
Pneumatic discharge control partially filled TFPNA as rainwater basin control in the sewer system
The reliable discharge control for wastewater and rainwater

Pneumatic discharge control partially filled TF-PNA

Precise and easy to maintain throttle system for stormwater tanks and wastewater structures. The fast, almost self-cleaning and remotely controllable butterfly valve with pneumatic actuator is based on the flow measurement integrated in the system and limits the flow to an arbitrarily adjustable quantity. As long as the maximum flow is not reached, the flap remains open, while the flow measurement system measures precisely even when partially filled.

Electrical planning

We are passionately committed to finding the optimal solution. In doing so, the trustful and close cooperation with the operator and planner is particularly important to us. Our company history began back in the 1960s; the large number of projects realised since then has provided us with extensive expert knowledge in industrial automation and electrical planning.
