Flottweg has developed a unique centrifuge concept specifically for high-degree dewatering of sewage sludge: the Flottweg X Series. Sewage sludge dewatering offers enormous potential savings for the operators of sewage treatment plants. The costs of transport and disposal of the dewatered sewage sludge frequently make up 80% of operating costs. Depending on the capacity of the plant, 1% more dry substance in the dewatered sewage sludge can represent cost savings in the five- to six-digit range.
