TLDR
In this article, the treatment of water by a biological technique is described, where the water to be treated circulates in the interior of the reactor, in the space (2) located above the partition (1), it is aerated and agitated by a diffuser (3); it enters the reactor by the opening (4) and leaves by opening (5).Abstract:
The treatment of water by a biological technique. The water to be treated circulates in the interior of the reactor, in the space (2) located above the partition (1). It is aerated and agitated by a diffuser (3); it enters the reactor by the opening (4) and leaves by the opening (5). A volume of confined water, poor in oxygen, occupies at the bottom of the reactor the space (6) located below the partition (1) and has across its thickness a layer supersaturated in oxygen (10) occupied by the microalgae and aerobic microorganisms; a region rich in oxygen (11) occupied by aerobic microorganisms; a region (12) poor in oxygen and occupied by anaerobic microorganisms; and an intermediate region (13) occupied by aerobic and anaerobic microorganisms. The invention is applicable particularly, in its closed circuit configuration, to aquaria and by means of either a closed circuit or an open circuit, to the treatment of water.read more
