Sludge and sewage thickeners - Import export

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

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.

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.

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.
