Underground Drainage

Sewage sludge dewatering offers enormous potential savings for operators of sewage treatment plants. Dewatering sludge means reducing the quantity of sludge for disposal. Depending on system capacity, 1 percent more dry substance can lead to cost savings in the five- to six-digit range. The dewatering performance of the Flottweg Xelletor Series is significantly better than even its predecessors. It sets new benchmarks for throughflow, dry substance, and polymer and energy consumption. The Xtra in performance at low consumption in comparison with our high-performance C Series: ►Xtra dewatering performance: Up to 10 percent less sludge volume due to higher total dry solids in dewatered sludge ►Xtra polymer savings: Up to 20 percent savings on flocculant consumption ►Xtra capacity: Up to 15 percent more throughflow ►Xtra energy savings: Up to an additional 20 percent energy savings

In small sewage treatment plants, investment costs play a decisive role. In stationary dewatering systems, for example, the construction of a new building can be significantly costly. You can avoid those costs with mobile container systems for sludge dewatering. Container-based solutions are a practical alternative to fixed dewatering installations.. A container is a true "plug and play" option – just connect it and start dewatering. ►Sludge dewatering in a one-man operation: comfort and personal safety, with control of the dewatering installation directly on-site. ►Year-round comfort: raised roof; insulated walls and roof, consistent use of stainless steel. ►Minimized maintenance effort: The roof can be opened by a single person using a manual hydraulic lifting system; the decanter can be opened with a crane built into the container. ►Optimized for operation in the smallest of spaces ►Easy transport with all current truck types

We know the special requirements of the wastewater industry. Flottweg therefore decided to create a new decanter series solely manufactured for sludge separation, called the Flottweg C Series.
