Abstract

The filter for clean water installations (1) comprises a first level with one or more water inlets (2), a first filter bed (3) and a second level with one or more first water outlets (4), through which the filtered water exits. It includes a second filter bed (5) that additionally filters part of the water, and a third level with one or more second water outlets (6). Most of the inlet flow is released through the first outlet (4), while the rest is released through the second outlet (6). The first filter bed (3) may be made of clay and arranged above the second filter bed (5). The water outlets (4) and (6) are located at the lower end of the first bed and below the second bed, respectively.

Abstract

Disclosed are methods, systems and devices to optimize communication between two electronic devices, which use the LoRa communication technique, when at least one of the devices is immersed in water such as a swimming pool or spa. The disclosed methods and systems allow the devices involved to automatically select (without making any external consultation) the configuration parameters that best adapt to the specific conditions of the pool (construction materials, wiring, etc.), environmental conditions (temperature, humidity, etc.) and the water (salinity, temperature, chemical composition, etc.).

Abstract

A filtration medium (6) for a filter for a water recirculation system comprises a first layer (101 ) arranged between and adhered to a second layer (102) and a third layer (103), the first layer (101 ) being a non-woven nanofiber layer. A filter assembly (1 ) for a water recirculation system comprises a container (2) with an inlet (3) and an outlet (4), and a cartridge (5) with a filtration medium (6) rotatably arranged inside the container (2). The filter assembly further comprises at least one cleaning diffuser (8) with a plurality of openings (81 ) directed towards the filtration medium, the diffuser (8) being placed within the container, between a wall of the container (2) and the filtration medium (6).

Abstract

The invention relates to a lid for a filter, characterised in that it comprises means (3, 4, 6, 7, 10, 14) for the chemical treatment of a fluid, such as injectors (6, 7, 10), electrodes (14) and/or probes (3, 4) arranged on said lid (1). Said injectors (6, 7, 10) can be used to inject disinfectant/oxidant, flocculant and/or a product for decreasing or increasing the pH, and said probes (3, 4) can be probes for controlling the level of disinfectant/oxidant and/or the pH in the fluid. This allows the production of a single filter wherein a physical treatment and a chemical treatment can be carried out, that provide a complete treatment in accordance with sanitary standards.

Abstract

Hydrocyclonic cleaning prefilter (1) fitted into filtration systems in water installations which incorporates a body formed by a reservoir (2) and an outlet cover (3), the interior of which comprises a disc-like distribution supporting member (4), a cyclone body (5) and a diffuser (6), wherein the diffuser (6) and the cyclone body (5) form a compact assembly, with the cyclone body (5) surrounding the diffuser (6), and in which both elements are connected in the inner part of the cyclone body (5). The prefilter includes a component (7) for facilitating discharge of the solid particles which is located in the lower part of the reservoir (2), between the lower part (8) of the central conduit (28) for the ingress of water into the reservoir and the particle-outlet aperture (9).
