摘要： Present invention relates to a method and apparatus for purification of water, said method comprises the steps of feeding the water into a reactor (4) through one or more inlet tubes (1) or inlet zones and feed water an substrate through carrier elements for bio film (5) which have a large protected surface (>200 m2/m3 carrier elements) and large pore volume (>60%), and that the carrier elements are fluidized for the removal of waste sludge, wherein the ratio of charge of the elements (5) by normal duty corresponds to an amount corresponding to 90%-100%, more preferred 92%-100%, and most preferred 92%-99% of the vet volume of the reactor (4), said carrier elements (5) is kept substantially at rest or hindered movement between the times surplus sludge is removed, and that the carrier elements being fluidised for removal of surplus sludge, said carrier elements (5) having a specific gravity in the area of 0.8-1.4, more preferred 0.90-1.1 and most preferred 0.93-0.97, and feed the treated water to one or more outlet zones (7) and one or more outlet tubes (2). The invention also comprises a reactor for performing the method.

摘要： 596609 A reactor (4) for aerobic, anoxic or anaerobic purification of waste water is disclosed. The reactor comprises one or more inlet pipes (1), one or more inlet zones, one or more outlet zones (7) and outlet pipes (2) for water and substrate, one or more outlet pipes for sludge (3), and one or more mixing mechanisms (6) for transport of water and substrate. The reactor also comprises a filling of carrier elements (5), on which a biofilm may form. 90%-100% of the reactor liquid volume may be constituted by the biofilm carrier elements during normal operation of the reactor. During normal operation, the carrier elements are not free to move. During sludge removal the water level in the reactor is raised such that the carrier elements become fluidised and are able to move freely with the help of one or more of the mixing mechanisms. A method for biological purification of water is also disclosed.
