Method and device for purification of wastewater
2006 (English)Patent (Other (popular science, discussion, etc.))
The present invention relates to purification of wastewater such that the content of sludge constituting sub millimetre particles can be reduced in the purified water. A method and an arrangement is provided comprising passing the wastewater through filtering means for filtering suspended material, whereby filtered water is obtained, passing the filtered water through a separating means adapted for separating oxygen consuming matter from the filtered water, whereby separated water is obtained, passing the separated water through a sorption unit for reducing the water phosphorous content, whereby phosphorous reduced water is obtained, characterized in that the method further comprises at least substantially separating sludge constituting sub millimetre particles from the filtered water prior to the step of separating the oxygen consuming matter from the filtered water, by passing the filtered water to straining means, thereby substantially reducing the sludge content of the obtained phosphorous reduced water.
