Centrifuge for sewage sludge dewatering
Efficiently reduce sludge volume and cut disposal costs by harnessing effective dewatering technology, refining processes for industrial and municipal applications.
The Flottweg HTS Decanter is a specialized centrifuge designed for efficient sludge dewatering in wastewater treatment facilities and industrial settings. This equipment excels in reducing sludge volume through centrifugal force, transforming wet sludge into dewatered solids for easier disposal. Engineered for applications ranging from municipal sewage to industrial waste management, it effectively processes a variety of feedstocks including sludge, oil residues, and mining byproducts.
With a capacity to increase dry solids content from as low as 2% to as high as 35%, the HTS Decanter drastically reduces overall transportation and disposal costs—up to 80% in volume reduction and 8% in disposal savings. Its Simp Drive® technology and refined geometry ensure superior energy efficiency, cutting electricity consumption by 20% when equipped with the optional Recuvane® system.
Fully automated and capable of remote monitoring, this decanter integrates seamlessly into existing operations with continuous, PLC-controlled processing, eliminating frequent manual interventions and unnecessary operational downtime. Available in materials optimized for corrosion resistance, maintenance is simplified with onsite replacement of parts and robust wear protection features, ensuring longevity and reliability. Whether processing municipal sludge or refining biofuel feedstock, the Flottweg HTS Decanter offers adaptable solutions with potential for customization to meet specific plant requirements.
