  • In-room hydroponic air cleansing unit
    Patent number: 9445557
    Abstract: The unit arranges plants around a media-cylinder in a vertical hydroponic configuration. The unit passes room-air over the roots of the plants, and significantly cleanses the air in a large room of contaminants. The unit is placed to receive light from e.g a window of the room. The unit includes provision for rotating the media-cylinder about a vertical axis, to ensure even illumination of all the plants around the media-cylinder.
    Type: Grant

  • Support for vertical hydroponic plants matrix
    Patent number: 7243460
    Abstract: The plant roots are embedded in a fibrous matrix material, which is oriented vertically. The matrix material is fixed to a support structure using a grid of fasteners. The support structure may be standard corrugated plastic sheeting, or a moulded plastic sheet. If biodegradable materials are used, they must be protected from humidity etc. The fibrous material is strong enough to support itself, and the embedded plants, between the fasteners, so long as the grid spacing of the fasteners is less than ΒΌ-meter.

  • Room air cleansing using hydroponic plants
    Patent number: 6727091
    Abstract: The plants are disposed on a near-vertical matrix panel of porous or fibrous inert material, in which the roots of the plants are embedded. Hydroponic water trickles down the panel, keeping the roots wet. A fan draws the air to be treated horizontally through the panel. The unit freshens stale air in a room. It may be provided as a wall-mounted unit, or as a self-standing tower unit.

  • Plant based system for abatement of gaseous ammonia contamination
    Publication number: 20040063194
    Abstract: The air in a room can be cleaned of ammonia by passing the air through green plants grown hydroponically. The air passes through a falling curtain of droplets of the hydroponic water, whereby the ammonia goes into solution in the water. Microbes colonised on the roots of the green plants break down the ammonia in the hydroponic water, and assimilate the nitrogen into the plant tissue.
