Abstract: Waste water conditioning has nearly 150 years of history. During this time, a method has developed that is considered to be state of the art. While this method meets the requirements at hand, it is complicated and expensive. The novel method breaks down the rigidly entrenched method and simplifies it. In a plurality of stages, the only energy that is used is gravity, which is readily available and free of cost. Thus, an “alternative sewage treatment plant” has been developed, which has a simpler method and is less expensive in terms of investment costs and operating costs, at the same capacity, and requires only a fraction of the previous required surface area. The most important characteristic of the invention is that the novel method separates solids from waste water immediately after entering the sewage treatment plant. Mechanically purified water is much faster, easier and less expensive to purify. The paths pursued for conditioning of the sludge are also new.
