The Oberregenbach sewage treatment plant of the town of Langenburg (D) is located between Stuttgart and Nürnburg and treats the waste wa-ter of about 1,800 inhabitants. Located on the foot of a slope, the water from the storm-water basin runs down a steep canal. Before the STE-BATEC drain controller was installed, the waste water was slowed down by a mechanical scale throttle before it entered the sewage treatment plant. The scale throttle was clogged regularly with theresult that only eight liters a second entered the sewage treatment plant instead of the maximum possible inflow of 35 l/sec and the rest entered the main drain without treatment.
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.
