- Low-maintenance system for travel up to 100 m - Other sizes and versions available, travel up to 200 m and more with E2 roller e-chains® - Protection against weather and dirt exposure - Cost-effective and fully enclosed complete solution - Standardized and modular design - Simple wall assembly or optional floor mounting - Cable lengths up to 50% shorter than festooning, low-profile installation and no cable junction - Cables are at all times guided with a defined bending radius, and tensile forces are absorbed by the e-chain® - Cables cannot hook, jam, or tear - No slip ring contacts (as is the case on motor drums) -Cables or hoses can easily be retrofitted at any time Reduce electricity costs - direct drive due to scraper, no additional drives needed (as is the case on motor drums) Scraper arm (e.g. as mechanical connection to the scraper carriage) optionally available - we document the situation on-site and will propose a customised solution

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.

Proven know-how meets state-of-the-art technology. This is the best way to describe the new Flottweg decanter C series. We also have the optimal solution for the very large wastewater treatment plants. The combination of our own Simp Drive® drive system, which has been in use since 1994, and Recuvane®, which allows flexible and simple retrofitting as well as targeted discharge of the centrate water, sets new standards for Flottweg in separation technology.

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.
