摘要
The water proceeds sequentially through a plurality of aeration stages of which each is connected to a delay and/or reaction chamber. After the aeration, the water remains in the delay and/or reaction chamber for establishment of equilibrium and, possibly, reaction with added agents and/or biological oxidation. This treatment is repeated in the following identical stages. Precipitation or reaction products are taken off from the delay and/or reaction chambers. In the apparatus for carrying out the process, the treatment stages are arranged one above the other and are connected together by branch pipes in such a manner that the water can run first through all odd-numbered and then through the even-numbered aeration stages and reaction chambers. A pump makes intensive treatment possible by connecting one after the other the odd and even treatment stages. The pump can be bypassed by gate valves and the throughput can be doubled by parallel operation of the odd and even treatment stages. Process and apparatus make possible softening to any desired degree of hardness, deacidification, biological oxidation and nitrification independently of variations in the throughput in volume per unit of time.
