Decanter centrifuge for sludge dewatering
5 - 150 m³/h (45 - 660 gpm) | HTS series Flottweg

In order to ensure cost-effectiveness, the dewatered sludge has to be as dry as possible for further processing - no matter if the dewatered sludge is transported, reused, disposed of in landfills or incinerated.
The FLOTTWEG HTS-DECANTER® (HTS = high dry substance) is the consequent step in development of Flottweg's Schnell-Dekanter® from the 1970s. It was developed especially for high-efficient dewatering of sewage sludge. The FLOTTWEG HTS-DECANTER® can handle sludge flow rates from 5 to 150 m3/h (45 to 660gpm).

FLOTTWEG HTS-DECANTERS® - advantages in comparison to other dewatering aggregates

-Rotor with extra long, cylindrical clarifying zone and optimized cone angle provides very high separation efficiency.
-Scroll with specially shaped feed zone, clarifying zone, and pressing zone in the conical part provides outstanding results in dewatering
-High bowl speed and resulting high centrifugal force allow for flexibility in order to achieve good dewatering results despite often poor sludge quality
-Compared to conventional decanter centrifuges, the dewatered sludge is up to 10 % drier with minimal polymer consumption
-Cake dryness generally equals the one achieved in filter presses with polymer conditioning and often exceeds it. Nearly constant cake dryness of the dewatered sludge, even with varying feed concentration and rates.
24-hour automatic operation possible
-Small footprint through high compactness and high flow rates
