FLOTTWEG XELLETOR Engineered For Your Success

The Next Evolution in Centrifugal Sludge Dewatering Sewage sludge dewatering offers a wide range of potential savings for the operators of sewage sludge treatment plants. Often, costs for transport and disposal of dewatered sewage sludge can amount to 80% of the operating costs in mechanical dewatering. Therefore, the decision to invest in a powerful and, above all, economic dewatering system is highly important. Since dewatering sludge means reducing the amount of sludge to be disposed of, this naturally leads to reduced disposal costs. Depending on the capacity of your system, just a 1...

THE MOST ECONOM FOR SLUDGE DEWA Optimize Your Process – Save Energy and Costs In order to find the optimum and, above all, most economical solution for your dewatering process, you should always consider all the important parameters, which include dry-matter content and capacity as well as polymer and energy consumption. This is where the greatest potential savings can be realized! Xtra Energy Thanks to our extra-deep pond concept, you will save up to 20% more energy compared to our conventional series. Depending on the capacity, the specific energy consumption for sludge dewatering is just...

Xtra Polymer Savings Polymer savings of up to 20% are possible with the same dry-matter content and quality of the dewatered sludge. Xtra Capacity Using the Xelletor system, it is possible to increase the capacity of your unit by an additional 15% with the same bowl diameter. This makes the Xelletor system an attractive option when it comes to refitting your plant. Xtra Clean In sludge dewatering, the separation efficiency of our centrifuges is in general greater than 99%, which reduces back-contamination in the centrate and thus saves additional costs.

THE SECRET OF THE XELLETOR SYSTEM The Evolutions of the Rotor and Scroll With the ultimate goal of maximum separation efficiency, the existing centrifuge concept has been continuously and radically analyzed by Flottweg engineers and technicians alike. At the heart of this continuous evolution is our revolutionary redesign of the centrifuge’s core component consisting of the rotor and the scroll. Inspired by the light-metal design of racing cars and bikes, we conceived the idea to build a scroll with the highest degree of stiffness without a scroll body. The resulting Xelletor series is...

1. The Basis – Efficient Solid-Liquid Separation Feed The liquid mixture to be separated is fed through a stationary pipe into the machine. The mixture enters the cylindrical part of the bowl through the scroll body and is then accelerated. “Pond” Due to centrifugal force a liquid ring is built inside the machine. The thickness of the ring is called the pond depth. The solids, or heavy phase, form a concentric layer at the bowl wall. The solids are discharged from the machine by the scroll via the conical part. The separated liquids are discharged through a weir. Solids Discharge The cone...

EFFICIENT, ECONOM The Xelletor Factors at a Glance Sludge dewatering on a new level: The Xelletor series combines our most recent sludge dewatering technologies and know-how. Over time, we have been meticulously collecting and evaluating both our customers’ demands and our process experiences. We have learned what is important to you. Based on this knowledge, we are continuously improving the performance of our centrifuges, while always keeping in mind economic efficiency when optimizing your processes, as well as the price performance ratio of our machines. Furthermore, you will benefit...

Master Saver ∙ dditional energy recovery thanks to the A Flottweg Recuvane® System Centrifugal Acceleration ∙ G-forces of up to 3500 in the Xelletor ∙ ue to these high g-forces, the sludge is pressed D out efficiently, thus resulting in an additional dewatering effect. ∙ n combination with the super-deep pond, the I g-force results in a high g-volume and thus a maximum separation effect. Automatic Is Good! ∙ ully automatic adjustment of the bowl and F differential speed produces optimum dry matter levels in the dewatered solids at any time, even in case of varying conditions in the feed. ∙...

LDATA Guaranteed Flottweg Quality Our Service – Always Available for You Typical “Made in Germany” quality: We have a very clear idea about quality and do not make any compromises here. Often, our customers have to deal with aggressive substances contained in wastewater. Therefore, we exclusively use rustproof and acid-resistant materials for wetted parts. Our optimally equipped machines will withstand your demands permanently – in extreme cases 24/7. Our strict quality controls (DIN ISO 9001:2015) as well as the ability to track all critical components provide additional product safety....
