<p>The invention relates to a method of providing an efficient separation and collection of pollutants in waste water by means of a separating and collecting apparatus (2). In first and second stages, respectively, of the filtering inner and outer liquid permeable filter containers (3 and 5, respectively) are used, which are formed of fabric (4 and 6, respectively) having comparatively more open and less open structure, respectively. The effective filtering area of both the first and the second stages extends substantially from an upper (2A) to a lower (2B) end of the separating apparatus (2) where they are integrated. A very high filtering capacity without any danger of clogging is obtained in this manner, by being able to separate and collect solid pollutants of different size over practically the entire filter surface in the different stages. A very high flow through capacity is thereby provided and maintained during a long period of time. The invention also relates to a separating and collecting apparatus (2) for providing such an efficient separation and collection of pollutants in waste water.</p> |
