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.

SMS offers sludge drying systems with horizontal thin film dryers for treatment of sludge from municipal as well as from industrial waste water treatment plants. Variations of this sludge treatment process are: Pre-drying up to 35 to 50 % dry solid content before incineration in fluidized bed incinerators 65 to 75 % dry solid content before combined incineration with garbage, composting or landfill Full drying up to 85 to 95 % before thermal utilization as bio-fuel for cement kilns, coal fired power stations, pyrolysis, gasification or other conversion processes before composting and agricultural usage as fertilizer and for soil reclamation In all these drying processes the thin film dryer is the first choice.

The demands on the quality and efficiency of sewage treatment plants are growing from year to year, not least due to rising energy and disposal costs. As a result, using decanters to dewater sludge means using state-of-the-art technology. The C-series decanters from Flottweg achieve high performance with reduced energy consumption. Flottweg Wastewater Decanters offer advantages over other processes and competitors' machines: ► High dry solids values in the discharged material ► Higher power density within a small footprint ► Powerful Flottweg Simp Drive® drive ► Reduction of operating costs due to reduced need for flocculant ► Additional energy recovery with the Flottweg Recuvane® system ► Economical bowl and scroll drive ► duces the energy consumption of your decanter by 10 to 30 percent

In the process of treating waste water, fine biological sludge is constantly produced during the decomposition process at a sewage treatment plant. For a stable decomposition process in the biological treatment phase, the sludge produced in the secondary sedimentation pond, also known as excess sludge, is removed and fed into the digestion tower. Flottweg's OSE decanters thicken the sludge before it enters the digestion tower. Sewage treatment plants benefit from an even feeding of the digestion tower and can thus optimally use the volume of the digestion tower. The Flottweg OSE decanter is specially designed for sludge thickening. ► Highest gas yield through constant feeding of the digestion tower ► Best possible thickening even with changing feed conditions ► Larger sedimentation volume (due to deep pond and steep cone) enables highest power density (10 - 20 percent) with minimum space requirement

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.

Flottweg has developed a unique centrifuge concept especially for the high-level dewatering of sewage sludge: The Flottweg Xelletor series. For the wastewater treatment plant operator, dewatering offers enormous savings potential. The costs for transport and disposal of dewatered sewage sludge often account for 80% of the operating costs of mechanical dewatering. The dewatering performance of the Xelletor machine is significantly better than that of our predecessor models. And it's setting new standards in terms of throughput, dry substance, and polymer and energy consumption.

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

The New C2E Decanter Centrifuges for Small Treatment Plants Flottweg presents a new era of sludge dewatering for small sewage treatment plants. The C2E decanter centrifuge was developed specifically for the dewatering and thickening of smaller sludge loading rates. It features all of Flottweg's know-how in a compact, space-saving design. Over five decades, Flottweg has gathered rich knowledge of the area of sewage sludge thickening and dewatering. That know-how has been transferred into a new generation of environmental centrifuges. Our requirements for the C2E are just as high as for the big Flottweg Decanters. Disposal costs still play a central role, even for small communities. The quality of the machine and its efficiency regarding separation results reduces the overall lifetime costs to a minimum. Want to learn more about our solutions? Then get in touch.

Transport and disposal costs, at over 70 percent, represent by far the largest cost item in sludge dewatering. A powerful dewatering assembly is thus an important criterion. With a Flottweg HTS Decanter in the C series, you can achieve the highest possible total dry solids in the dewatered sludge, thereby continuously saving on transport and disposal. More than 50 years of experience in the dewatering of sewage sludge and continuous further development have gone into the design of the Flottweg HTS Decanter. This experience, combined with references from the entire world, makes Flottweg one of the leading providers of mechanical separation technology. The HTS Decanter is attractive for its performance, its efficiency, and its high cost-effectiveness. The decanters in the Flottweg C series cover a throughput range from about 5 to over 150 cubic meters per hour. We can offer you comprehensive know-how and customized systems.

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.

Transporting recycling materials presents particular challenges for conveyor technology. The spiral conveyors for recycling materials need to be able to withstand materials with very different properties, unlike when transporting raw materials in industrial production processes or homogenous material such as granulates or pellets. In addition, the sturdiness in regards to environmental influences cannot be underestimated as a decisive factor for the longevity of the conveyor system as a whole.

We supply conveyor belts in various models for bulk goods. The model primarily depends on the transported quantities and bulk good properties. Conveyor belts / belt conveyors can also be used advantageously even across longer distances and with higher transport quantities. Conveyor belts with trough belt guides serve specifically to dispose of sewage sludge or for transporting wood. We also supply suitable scraper systems for your belt systems. It is also possible to fill the containers for container loading. A reversible and swivel-mounted conveyor belt also allows up to 6 containers to be filled. The advantage here is that the containers can be filled completely by moving/turning the belt. This container filling option is an alternative to pushing containers on rails.
