A method and an apparatus for removing filterable particles from water are disclosed. One or more filter bags made from a filter material suitable for filtering off the particles to be separated are disposed in a body of water with the bottom of the bag situated below the water surface and its opening situated above the surface. The water flows through the wall of the filter bag to the surrounding body of water, while the particles remain within the bag. After a certain amount of particles has been collected in the filter bag, backwashing is carried out and the particles removed and conducted to a place remote from the body of water. The method and apparatus are particularly suitable for restoration of lakes, rivers, water courses and similar water bodies.
