A method for reducing odor, by providing a colloidal dispersion of particles of silica having a particle size of from 3 nm to 100 nm, said particles having ions of one or more metals selected from copper, silver, zinc and iron adsorbed at the particle surface, and bringing at least one of said particles into contact with an odorous compound; and/or providing an aqueous silicate solution containing metal ions selected from ions of copper, silver, zinc and iron, and bringing at least one metal ion-carrying silicate particle formed in the solution into contact with an odorous compound. A composition for use in such a method and a product treated by such a composition.

The present application provides an intelligent air purification robot with a mosquito-repelling function. In the present application, a robot body has an obstacle detection function and can make a turn automatically. That is, the robot body can automatically find a path after being placed in a room, and can purify air everywhere in the room. Dust-laden air enters a housing from an air inlet and is then treated by a plurality of modular units. Moreover, a UV lamp is further provided, so that air can be disinfected at a designated position.

Described is a device (1) for reducing pollutants in a gaseous mixture comprising: a containment body (2) having an inlet portion (3) for the gaseous mixture and an outlet portion (4) for the gaseous mixture, the containment body (2) imposing on the gaseous mixture a fixed direction of flow (D), at least one filtering unit (10) comprising a photocatalytic filter (7) interposed, along the fixed direction of flow (D), between a first light source (6a) and a second light source (6b), both having a wavelength in the visible spectrum (400-700 nm), the photocatalytic filter (7) comprising a photocatalytic nanoparticle coating and the nanoparticle coating comprising titanium dioxide doped with a nitrogen doping agent. a unit (5) for straightening the flow before the filtering unit (10).

A filter system for adsorbing an odor of a gas flow in an industrial process includes a filter module (1) with a layer (11) containing active adsorbent (3). The layer (11) includes a plurality of active adsorbent containing permeable bags (2) arranged in close proximity to each other.

An apparatus for removing air pollutants from the air is described. The apparatus contains a fan module and a chamber that can hold either activated carbon or a gel that reacts with air pollutants from air.

A photocatalyst filter is provided. The photocatalyst filter includes: a base in which an internal space is formed. The internal space is permeable to fluid, and a plurality of photocatalyst beads are provided in the internal space, wherein a surface of the internal space is reflective.

A method of recycling an saturated adsorbent (3) of a filter module (1) of an industrial process plant (15), wherein a first process (17) includes removing the saturated adsorbent (3) from the filter module (1), a fourth process (20) includes washing and reactivating the saturated adsorbent, a fifth process (21) includes drying and packing the reactivated adsorbent in airtight containers, and a seventh process (23) includes replacing the saturated adsorbent by reactivated adsorbent in the filter module (1).
