Flottweg Decanters for sewage sludge treatment

Decanter Centrifuges for Sewage Sludge Treatment

Clean water is becoming an increasingly valuable raw material, which is why municipal wastewater treatment is becoming increasingly important to businesses on the global stage. To keep clean both soil and bodies of water, the sludge resulting from drinking water and waste water treatment must be separated as efficiently as possible. For the dewatering and thickening of sewage sludge, industrial centrifuges are now considered state-of-the-art. Not only this, moreover, they are also efficient, energy-saving and cost-effective.

Sophisticated Design and Engineering of Sewage Sludge Centrifuges for the Special Requirements of Today’s Sewage Treatment Plants

Flottweg has been in the dewatering and thickening of sewage sludge business for more than 50 years. The depth, breadth, scale and scope of our experience is why we understand and are able to deliver on the special requirements of sewage plants and water management.

Flottweg’s C-Series decanter centrifuges are powerful, efficient, and proven solutions for meeting the unique requirements of waste water treatment. It is important to note that dewatering and thickening of sewage sludge can be achieved efficiently only with a bowl, gearbox, and control system with distinct features. These features help ensure the maximum dewatering and thickening of the sewage sludge.

The Xelletor system, the latest in Flottweg’s continually evolving centrifuge series, is ideal for waste water treatment. This highly advanced system, in effect, revolutionizes the dewatering of sewage sludge. A scroll with the highest degree of stiffness without a scroll body makes this possible. Among the numerous benefits customers appreciate are extra dewatering performance, extra capacity, reduced consumption, and greater energy savings.

Greater Efficiency in Sewage Sludge Treatment

Reducing to the maximum extent possible the volume of sewage sludge is the number one goal in dewatering. Every tenth of a percent of higher dry-matter content in the sludge helps lower the cost of sludge disposal. Customers deploying the dewatering decanters in our C-Series and X-Series enjoy the benefits of reduced operating costs, lower energy consumption, and high dry-matter content.

For thickening, it is critically important to have a high separation degree and low polymer requirement. Both relieve the downstream process and improve overall performance of the waste water treatment plant. Flottweg decanters for surplus sludge thickening concentrate the dry-matter content of the sewage sludge to a few percent.

Our decanter centrifuges also are ideal for optimizing sludge thickening with starch polymer-based flocculants. Starch polymer is largely degradable and Flottweg decanters are known for achieving very good values.

Less Waterworks Sludge, Lower Cost

The treatment of drinking water produces waterworks sludge. Decanter centrifuges reduce transport and landfill costs of the sludge produced. The benefits are two-fold: They increase the dry-matter content and reduce the polymer requirement.

Flottweg Decanters Operational in Sewage Plants the World Over

Our specially designed and engineered decanters are found in a wide variety of waste water treatment applications the world over. Through our decanters, Flottweg’s growing, global portfolio of valued sewage treatment plant customers have significantly reduced their operating costs. For this and other reasons, they routinely express a high level of satisfaction in our products.
