Abstract: The presently disclosed subject matter refers to agro-photovoltaic modules (at times also referred to as agri voltaic modules) designed to increase the productivity use of available area. The agro-photovoltaic module can enable agricultural growth and the production of energy, e.g. by using photovoltaic cell(s), while using the same area (land space, lake, rooftop, etc.), therefore the agro-photovoltaic module can offer a good solution for this issue. This may help overcome legislations/rules in different countries, for example, where land can not be used solely for solar energy cultivation and must be integrated with agricultural purposes. The produced photovoltaic energy is either being used by components of the module or directed to an external electric power system.

Abstract: A cassette for supporting hydroponic growth of plants has an inlet, an outlet and a flow path that extends between the inlet and outlet. The inlet and outlet are located at a similar gating side of the cassette generally adjacent one to the other.

Abstract: A filter apparatus is used for at least partially removing dirt from a pressurized liquid flow passing therethrough. The filter apparatus includes a harvesting utility for harvesting electrical energy from the liquid flow, and at least part of the harvested electrical energy can be used for powering a cleaning mechanism of the apparatus that periodically cleans the filter apparatus.

Abstract: The presently disclosed subject matter is directed to a filtration system. The filtration system comprising a housing and at least one filter assembly extending within the housing. Each of the at least one filter assembly comprising a filter element disposed within the main filtering chamber; a cleaning assembly comprising a suction shaft. The suction shaft comprising at least one suction nozzle along a portion thereof, and being sealed at its one end and configured with at least one exhaust opening at its other end configured for extending within an exhaust chamber. Further comprising a liquid resistant driving mechanism disposed within the exhaust chamber and configured to impart the suction shaft with rotary motion and reciprocal linear motion. The suction shaft is adapted for selectively closing and opening the fluid drain port.

Abstract: The disclosed subject matter is concerned with a screen-type filter element, and a method for its manufacture. The screen type filter comprises a substantially rigid screen-bearing skeleton and at least one fine screen sheet material extending within or over the skeleton and secured thereto by a plurality of enveloping ribs, the enveloping ribs being applied over one face of the filter screen sheet to thereby support it at discrete portions and secure it to the skeleton.

Abstract: Provided is a fluid filtration assembly including a housing configured with one or more filter units extending in fluid flow between a raw fluid inlet port and a filtered fluid outlet port, a filter rinsing assembly being in fluid communication with a rinsing fluid inlet port, and propulsion fluid inlet port being in flow communication with a propulsion mechanism for propelling one or both of the filter rinsing assembly and the filter unit with respect to one another. Further provided is a thread tensioning mechanism for controlling tension of coiled threads of a thread-type filtering cartridge.

Abstract: Provided is a filter system including an exposed filtration media. The filter system further includes a raw liquid inlet flow path into a filtering side of the filtration media, a filtered liquid outlet flow path at a filtered side of the filtration media extending to a filtered liquid collecting port, a liquid pump for propelling liquid through the filtration media, and a rinsing mechanism for removing filtrate from the filtering side of the filtration media.
