10 years operation of the pneumatic outflow control

City of Wädenswil (CH)

In 2010, four stormwater tanks in Wädenswilon Lake Zurich were equipped with MID-controlled PNA pneumatic discharge controls. This system was chosen at that time because it could be easily retrofitted in the old tanks, requires little space and allows the throttle volume to be changed at any time. In addition, a complete throttle shaft from STEBATEC was installed in the rainwater reservoir Schlossgasse, which has an untypical geometry due to its location between the railway track and the rainwater reservoir.

Robust, transparent, accurate, fast, low maintenance and reliable for wastewater, raw wastewater and rainwater.
Precise drain throttle for heavily polluted waste water. The IDM flow measurement for full filling is the central element of the almost self-cleaning, remotely operated and highly precise pneumatic discharge control PNA. The reliable and never-tiring flap with pneumatic drive and the pinch valve react quickly to changing flows and conditions.
