PROCESS AND PLANT TO PURIFY POLLUTED WATERS

摘要

In the first step of the process and with the plant implementing it, the effluent mixed with air is blown at a pressure in the pipe network of at least 2 bars, and the stream of the effluent-air mixture is supplied at a distance from the bottom of the tank varying from about half the effective height of the tank to about the surface of the liquid in the tank, whereas in the second step of the process the effluent treated in the first step is stirred in the tank without blowing air by means of a stirrer that is able to break the biological foam previously formed.
