Sewage sludge dewatering offers enormous potential savings for operators of sewage treatment plants. Dewatering sludge means reducing the quantity of sludge for disposal. Depending on system capacity, 1 percent more dry substance can lead to cost savings in the five- to six-digit range. The dewatering performance of the Flottweg Xelletor Series is significantly better than even its predecessors. It sets new benchmarks for throughflow, dry substance, and polymer and energy consumption. The Xtra in performance at low consumption in comparison with our high-performance C Series: ►Xtra dewatering performance: Up to 10 percent less sludge volume due to higher total dry solids in dewatered sludge ►Xtra polymer savings: Up to 20 percent savings on flocculant consumption ►Xtra capacity: Up to 15 percent more throughflow ►Xtra energy savings: Up to an additional 20 percent energy savings

SYSTEM SOLUTIONS FOR SEWAGE SLUDGE DIGESTION In the municipal sector, the focus is on the production of biogas from sewage sludge. The aim is to make the energy potential of the primary and secondary sludge from anaerobic sludge digestion usable. On the one hand heat and electrical power is obtained for operation of the sewage plant. On the other hand, the sludge is conditioned so that the other aerobic process stages can run more efficiently and thus more cost effectively. The Lipp KomBio reactor has established itself as an ideal solution in the municipal sector due to its construction and long service life and has been successfully installed in hundreds of plants at home and abroad. Thanks to the application of the SBR process in our digesters, and the tank geometry and construction, it is possible to make optimum use of the low energy potential of the sewage sludge and operate sewage sludge digestion economically.

In small sewage treatment plants, investment costs play a decisive role. In stationary dewatering systems, for example, the construction of a new building can be significantly costly. You can avoid those costs with mobile container systems for sludge dewatering. Container-based solutions are a practical alternative to fixed dewatering installations.. A container is a true "plug and play" option – just connect it and start dewatering. ►Sludge dewatering in a one-man operation: comfort and personal safety, with control of the dewatering installation directly on-site. ►Year-round comfort: raised roof; insulated walls and roof, consistent use of stainless steel. ►Minimized maintenance effort: The roof can be opened by a single person using a manual hydraulic lifting system; the decanter can be opened with a crane built into the container. ►Optimized for operation in the smallest of spaces ►Easy transport with all current truck types

Grinding chips are created by the grinding of metal components. It is a mixture of metal and corundum abrasion in combination with the cutting fl uids being used. By briquetting, the waste is reduced significantly and the briquettes possess a defi ned residual moisture. Thus, the disposal costs are reducedand depending upon the alloy, there is even the opportunity to sell the briquettes with a profit. In most cases, the expensive oil contained in the cutting fl uid can be reused. The briquetting system can already payoff for itself within less than 12 months by processing about 10 to 30 tons of the expensive oil contained in the cutting fl uid per year. Depending on the requirements, our briquetting systems for grinding chips are equipped with hydraulic motors ranging from 4kW to 22kW, and reach a specifi c pressure of up to 3,800 kg/cm². The throughput of the RUF briquetting systems - especially for grinding chips - range from 40 to 350 kg/h.

Waste water treatment plants and surface waters have enormous energy potential. A sewage treatment plant, for example with 90 million litres of wastewater daily, reducing the wastewater temperature by using heat exchanger by around 1°C, generates a power of about 4.3 MW. The comparative potential for energy recovery from the surface water is even higher. Environmental aspect Induced by humans, water temperatures of the surface and streams have steadily increased, not least owing to the inflows from sewage water treatment. This has serious consequences on the flora and fauna. If heat is extracted from purified water in the sewage treatment plant or from surface waters and from streams, and water temperature is thereby reduced, this will have a positive effect on the entire ecological system. With KASAG heat exchanger systems, on the one hand, the energy requirement of the sewage treatment plant can be covered and, on the other, buildings in near vicinity can be heated or cooled.

Like all machine sizes in our C series, the C5E is also equipped with optimum wear protection. This reduces maintenance costs, as only wear parts need to be replaced. At the same time, this ensures a longer service life and high machine availability. The Flottweg features Recuvane® and Simp Drive® make the simple, efficient and individual operation of the centrifuge perfect.

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.

This new decanter series combines the latest know-how in manufacturing, design and engineering with decades of experience. Thus, with the C4E environmental centrifuge, we offer an optimal solution for medium-sized wastewater treatment plants for which quality, reliability and a good price-performance ratio are important.

We know the special requirements of the wastewater industry. Flottweg therefore decided to create a new decanter series solely manufactured for sludge separation, called the Flottweg C Series.

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.
