Leachate treatment in a stripping column
After the first physical and chemical treatments of the leachate, it is further treated in an approx. 3 m high reactor, the so-called stripping column. Here, nitrogen and carbon compounds are broken down with the help of microorganisms. A filling material is packed into the middle area of the reactor to improve the reaction. In additional physical processes the treated leachate is cleaned, evaporated and separated as a distillate. An exact level measurement at the base of the stripping column is required for optimal operation.
Level measurement with VEGAFLEX 63
The surface of the medium in the reactor is very turbulent due to air streaming in from below. A direct level measurement in the stripping column is therefore not possible. That’s why the TDR sensor VEGAFLEX 63 in conjunction with a bypass tube is implemented here. The bypass tube itself together with the probe rod forms a coaxial system. A reliable measurement is thus guaranteed, even when there are welded seams and deposits in the bypass tube and overfilling right up to the sensor occurs.
