The invention regards an apparatus (1) for the purification of unclean water (A), in particular of wastewater and/or polluted water (A), comprising: - at least one container (2), preferably cylindrical, delimiting a reaction chamber (3) arranged to receive a predetermined amount of water (A) to be treated; at least one support (11), preferably at least one free body (11a) not constrained to the apparatus (1), operatively arranged inside the reaction chamber (3) of the container (2) and provided with at least one surface for the formation and/or the proliferation of bacterial colonies in form of films capable of purifying unclean water (A), the support (11) periodically emerging, at least partially, from the water (A) to be treated in order to place the bacterial colonies into contact with the air. The container (2) is movable, in particular rotationally about a predetermined rotation axis (X), for periodically driving the support (11) between an immersed condition, wherein it is totally covered with water (A) to be treated, and an emerged condition, wherein it emerges, at least partially, from the water (A) to be treated. |
