<p>The method comprises subjecting grey water to aerobic biological treatment and then to filtration process, which is carried out under utilization of hydrostatic pressure of stored and/or treated grey water. The grey water to be treated is introduced in a grey water container (1) for storage and/or treatment. The interior area of the grey water container is arranged in lower area of a filtration device. The clarified water received after the filtration step is directly taken from the filtration device and is guided from the external side of the grey water container. The method comprises subjecting grey water to aerobic biological treatment and then to filtration process, which is carried out under utilization of hydrostatic pressure of stored and/or treated grey water. The grey water to be treated is introduced in a grey water container (1) for storage and/or treatment. The interior area of the grey water container is arranged in lower area of a filtration device. The clarified water received after the filtration step is directly taken from the filtration device and is guided from the external side of the grey water container. The grey water to be treated is guided before the storage and/or the treatment, through a pre-filter or coarse filter (4) with a sieve width of greater than 1 mm. The filtration step comprises a microfiltration or ultrafiltration. The stored and/or treated grey water is aerated by filtration unit. The filtration is carried out after termination of the treatment and/or the filtration step is interrupted in regular intervals. The clarified water is conducted and stored in a rain water container and/or drinking water container. The clarified water is conducted from a clarified water container (2) through a submersible pump (27) arranged on the base of the clarified water container. An independent claim is included for a device for processing of grey water to clear water.</p> |
