X7E decanter centrifuge

Honored with the German Innovation Award 2019, the Xelletor series is one of the greatest achievements in the field of sewage sludge. Dewatering sewage sludge is standard for wastewater treatment plants and since it usually has to be transported away, operators have an interest in separating as much water as possible from the sludge. This saves weight and thus reduces costs. Savings of up to 10% in sludge volume and 34% in energy consumption are possible. Our Xelletor high-performance centrifuge inspires customers all over the world with the many years of technical know-how and innovative spirit behind it.

Innovationen sind Flottweg Spezialität. Unsere Xelltorbaureihe spiegelt Erfindergeist, langjährige Erfahrung und technisches Know-How in einer Maschine wieder. Auf Kläranlagen ausgelegt ist die X5E für mittelgroße Kläranlagen die optimale Lösung, wenn es um Schlammentwässerung und Schlammeindickung geht. Die Kosteneinsparung hinsichtlich Entsorgung und Transport ist für viele Kläranlagenbetreiber der ausschlaggebende Punkt, sich für den Flottweg Xelletor zu entscheiden.

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

Flottweg C series decanters around the world process 25 million liters of sewage sludge per hour. The dewatering and thickening of sewage sludge plays a decisive role in the wastewater treatment process. Requirements for the quality and efficiency of sewage treatment plants increase year after year, not least driven by the increasing costs of energy and disposal. As a result, the state of the art is now to use decanter centrifuges to dewater and/or thicken the incoming sludge. Flottweg developed the decanters of the C series especially for this purpose. The C7E represents the largest of all the C machines. The C7E increases the proportion of dry substance in the sludge, thereby reducing its volume and weight (due to loss of water). That means that operators need to dispose of, recycle, or burn less sludge. The result: enormous potential savings for the operators of sewage treatment plants.
