Abstract
A deputation process and corresponding apparatus for purification of the air of a closed environment characterized by indoor pollution, in which, in order to reduce the pollution, a water tank is provided that contains a multiplicity of active biomasses designed to absorb and metabolize the pollutant substances that are contained in the water and come from the air of the closed environment, and elements of water-air contact, designed precisely to transfer the pollutant substances from the closed environment into the water within the tank.
Claims20
A depuration apparatus for the purification of air of a closed environment configured to reduce or eliminate the pollutant substances contained in the air of the closed environment, comprising:
- a tank (V) containing water;
- a plurality of active biomasses (B) immersed in the tank (V), the plurality of active biomasses (B) being designed to absorb and metabolize the pollutant substances that are contained in the water, the plurality of active biomasses (B) being supported by a purposely provided substrate (S);
- means for water-air contact, designed to transfer said pollutant substances from the air of the closed environment to the water of the tank (V) itself, the means for water-air contact comprising a cover (C) for the tank (V), said cover being equipped with means for determining contact of the polluted air with the water of the tank (V), with means for enabling the air filtered by forced contact with a surface of the water to be released into the environment itself, and with means for illumination of the tank;
- means for forcedly conveying the air of the environment to a system for wet-filtering and contact of the air with the water itself;
- and
- biological means for purifying the water from the pollutant substances transferred thereto and coming from the air of the closed environment, wherein
- in order to increase the surface of contact between the water and the air there are provided means for increasing turbulence of the air in the tank (V) and hence moving the water.

- and
- biological means for purifying the water from the pollutant substances transferred thereto and coming from the air of the closed environment, wherein
- in order to increase further the surface of contact between the water and the air there are provided one or more rotating rollers or disks (5), which are partially immersed in the water;
- said rotating rollers (5) being, designed to present a wet surface to the air that impinges on them and to transfer to the water the substances that have adhered thereto.
