Successful introduction of the new C-series – an innovation conquers the market

Concerning waste water decanters, the most important objective of Flottweg developments is the maximum dewatering of the sewage sludge. The dryer the dewatered sludge, the easier it is to dispose of it and the more it helps the operator to save money.
Due to the new C-series, which was launched in 2008, Flottweg succeeded in increasing the capacity of its machines and at the same time reduce energy consumption up to 20-30%.

Minimal Operating Costs

Efficient acceleration of the product in the feed zone combined with very specific internal scroll designs results in smaller installed horsepower requirements and lower overall power consumption of the motors (up to 20 – 30 %). This is a dramatic reduction of power consumption.

Lower Investment Costs

Due to higher internal sedimentation volume, the capacity of a similar-sized machine is increased by 10 – 20 %, which ultimately results in lower investment costs since it is now possible to use a smaller machine for the same feed rate without suffering in processing performance. This helps the end user overcome capacity bottlenecks without sacrificing centrate or discharged cake quality.

Type series

Since the summer of 2008, more than 100 decanters of the new C-series have been installed and run in different waste water applications. The three available models C3E, C4E, and C5E cover processing ranges up to 90 m3/h (44 – 396 gpm).
