Siemens retrofits clarifiers at Denver wastewater reclamation plant

The Siemens systems are valued at more than US$3.5 million and are part of a two-phase plant expansion project. The clarifiers are expected to be shipped in 2012, with five projected to come online in 2013 and the other five in 2014.

The ten 140 ft diameter Siemens Tow-Bro high-performance clarifiers will be retrofitted into existing concrete basins for rapid settled secondary sludge removal from the clarifier, with maximum solids concentration and minimum sludge agitation. The Tow-Bro clarifier will remove settled solids uniformly under a wider variety of flow, solids loading, and sludge settling conditions.
