The invention relates to an apparatus for treatment of water comprising inclined lamellae arranged so that settling materials as well as floating materials are separated from the water. The apparatus is devised so that the water flows in opposite directions through separate spaces between the lamallae, wherein heavy materials (sludge) settle to the bottoms of the spaces while floating materials (scum) are retained and separated in a chamber where the water changes its direction of flow. The apparatus may be arranged for separation of sludge in two fractions and for purification of the water by a combination of flotation by aeration and settling. The apparatus is useful for all types of purification processes based on separation by settling and flotation within the water and sewage treatment art. Especially of interest is the favorable application of the apparatus for treating storm water and overflow water.
