PROCESS AND APPARATUS FOR PURIFICATION OF WATER CONTAINING SUSPENDED MATERIALS AS WELL AS INDUSTRIAL SEWAGE WATER

摘要

The invention relates to an apparatus, for cleaning waters and/or industrial sewages containing floating materials and/or materials suitable for forming suspension, comprising collecting vessel, flotation vessel, foam collecting vessel, vessel for producing flotation medium, resp. foam- and water-bypipe. The collecting vessel comprises a mixing vessel (1) and a flocculating vessel (2), thereto the sewage inlet pipe (11) and the chemicals inlet pipe (13) are connected, while the other end of the vessel (1) towards the vessel (2) is open, thereto on the bottom, a pipe (24) charging the flotation medium and chemicals is connected, the vessel (2) is encircled by the flotation vessel (3), then the air absorbing vessel (5) encircles the vessel (3), and to one of the inlets of the vessel (5) is joined a pipe (17) for producing the flotation medium with water-fog vaporized with high-pressure, to the vessel (3) is connected a pipe (33) for forwarding the flotation medium, while to the bottom of the vessel (3) is connected a further bypipe (26) for the clean water-phase.
