A collecting unit and method for assembling the collecting unit are described in the present disclosure. The unit comprises a detachable frame structure and a collector arrangement. The frame structure comprises legs and a hub having holes on the surface of the hub. A first end of each of the legs is inserted in at least one hole of the hub. The arrangement comprises a collapsible plane having a first side for collecting a substance and a bottom side facing hub. Connecting assembly is provisioned for establishing a connection between each corner of the plane and the second end of the corresponding leg. The collector arrangement further comprises a geometry defining mechanism to define the geometry of the plane.

An apparatus provides a water bottle mouthpiece attachment which can filter microplastics and other contaminant substances from bottles, particularly disposable plastic water bottles. The filter of the apparatus includes a filter housing that is attached to a cap that fits inside a common plastic bottle. Soft rubber rings, tapering from to radially larger on the top to radially smaller on the bottom in a generally conical fashion, ensure a watertight fit to the inside opening of any drinking bottle. A friction closing/opening spout at the top of the filter enables selective opening of the bottle and prevents accidental spillage of bottle contents. The filter housing is also offset from the center, giving space to an air valve that allows air to enter the bottle without disturbing the flow of water from the bottle, thus providing optimal lamellar flow without allowing fluid to escape through the air valve during consumption.

The present invention relates to a photovoltaic facility (1) comprising a solar tracker (2) and at least one square or rectangular photovoltaic panel (3) mounted on the solar tracker (2), this solar tracker (2) enabling the inclination of the photovoltaic panel (3) to be varied with respect to the horizontal, so that two opposite edges of the photovoltaic panel, referred to as horizontal edges (31), are always horizontal whatever the inclination of the photovoltaic panel (3). This facility is characterised in that it comprises at least one gutter (4) for recovering rainwater, in that this gutter (4) is mounted along one of the two horizontal edges (31) of the photovoltaic panel (3) using at least two anchoring devices (5), to which it is suspended, so that it can oscillate under the action of its own weight, about a horizontal axis of rotation (Y-Y′), so as to remain horizontal whatever the inclination of the photovoltaic panel (3).

A method and rainwater processing system are disclosed. According to one aspect, a method includes collecting rainwater, filtering the collected rainwater, and ozonating the filtered collected rainwater to produce potable water. The method includes diverting a portion of the collected rainwater to a test chamber and testing by sensors the diverted portion of the collected rainwater to produce a valve control signal. Responsive to the valve control signal, a valve is opened to channel collected rainwater to a collection tank and filtered. The method includes ozonating the filtered collected rainwater to produce potable water. A functional water may be prepared by adding a substance to the potable water within a processing tank. The functional water may be carbonate and ozonated.

An engineering system for collecting and utilizing regional rainwater includes a rainwater collection system, a water quality treatment system, and a control and allocation system. The rainwater collection system includes a rainwater collection ditch for a hardened underlying surface, a barrier and a water storage tank. The water quality treatment system includes a filter system. The control and allocation system includes a water quality monitoring device, a water level monitor, a control gate and a water pump. The filter system is connected to the underlying surface through the rainwater collection ditch, and the filter system is connected to the water storage tank. The control gate is disposed between the filter system and the water storage tank. The water quality monitoring device and the water level monitor are disposed within the water storage tank. The water pump is used to drain water from the water storage tank.
