device for omsettning of in water, especially waste water, fororeningar approaches, especially skadeemnen to harmless emnen

摘要

An arrangement for converting foreign and harmful matter found particularly in sewage water, in which the foreign matter is converted into harmless materials. A conversion tank with an intake for the water to be treated and having a drain for the treated water, is provided with rotating tubular members with perforations. These tubular members in the form of pipes, emerge on one side completely out of the water, whereas they are immersed on the otherside entirely into the water. The pipes are filled with materials which are insoluble in the water and which have a large surface area accessible to air and water. The pipes are carried by spoked wheels on a shaft, and they are paralel to each other as well as to the water surface. The perforations may be in the form of slots having parallel axes.
