Cross-flow lamella settler successfully tested

This week, the demo case Emscher in Germany had a first and successful test run of the cross-flow lamella settler. The container solution, developed by the company UFT, has been installed at a CSO in the Emscher area in May/June. The University of Duisburg-Essen equipped the container with two automated samplers and scan probes for real time-measurements of suspended solids, COD and BOD at the in- and outflow, allowing to determine the container’s sedimentation efficiency. The first test operation with sewage water worked out very well and the next rain events are anticipated!

The demonstration container has a volume of around 25 m³ and is placed close to a combined sewage overflow tank. During rain events, combined sewage is pumped into the vessel. It features two cross-flow lamella modules with a projected lamella surface of 33 m². The settling solids in the combined sewage will settle on the large surfaces and the overflowing water will thus be mechanically pre-treated.

Thus, DESSIN milestone MS22 has been achieved.
