Abstract (en)
[origin: WO2010081471A2] Sewage treatment has a nearly 150 year old tradition. During this time a method has been developed that is considered to be state of the art. Said method does meet the requirements presented, but is complicated and expensive. The novel method breaks open the rigidly established technology and simplifies the same. In a plurality of process steps, only gravity is used as the sole energy source, which is available everywhere and costs nothing. In said manner, an "alternative sewage treatment plant" was developed that is simpler in method at the same capacity and is less expensive in investment and operating costs, and requires only a fraction of the previously required area. The most important characteristic of the invention is that the solids are separated from the sewage immediately after entering the sewage treatment plant using a novel method. The mechanically purified water can be purified more quickly, easily, and cheaply. Novel paths are also taken in sludge treatment. The sludge is considered to be an energy carrier or resource that should be used accordingly. According to the invention, the prerequisite for using the sludge is also achieved by economical drying to 95-98% dry solids.
