The invention is related to a method for cleaning fish or swimming pool water and to a device solution, in which cleaning devices (1) are placed relative to the water level of the pool so that an impeller (2) sucks the water to be treated, lifts its level in a treatment pool (1), sucks air (c) to the impeller (2), which mixes it into small bubbles and disperses it in the water, whereby the impurities in the water, such as oil, fat, light and floating impure solids, combine with the air bubbles and change lighter and lighter, whereby, by means of a specific-weight separation formed by pipe channel sections (4, 7, 8 and 15), floating particles and foam (14) rising to the surface can be guided to rise upwards and leave via a separate opening (13) as a flow (e) out of the pool (1), whereby clean, so-called heavy water goes downwards over an edge (8) and from between concentric pipe channels (4 and 15), extending from above (from above the water level) downwards from the cover into the outlet channel, into a closed channel (10) and therefrom to be directed by a flow (b) either back to the pool water (12) or out to a common watercourse. The suspension and foam flow (e) is directed into a separate desired destination for recovery. The lower edge of the pipe channel (15) has to be located lower than the upper of the funnel (8). The treatment can also include disinfection, in which case a suitable chemical realizing the disinfection can be added to the channel (4) as a flow (d), or at the same time, a chemical can be added, with which phosphor to be removed from the water precipitates and is driven, lifted by air bubbles, to the foam and as a flow (e) out of the system. Possible nitrogen oxidizes into nitrate and does not form ammonia, since the entire water system is oxidative, i.e. oxygen-rich water. |
