A B S T R A C T: Apparatus for the anaerobic purification of waste water. In apparatus for the anaerobic purification of waste water the invention aims at improving the structure and the operation. In known apparatus of this kind there is a reactor tank with one or more aftersettling compartments in the upper part thereof, with inlet and outlet openings for water and sludge into and from the aftersettling compartments from and into the reactor tank respectively, Such apparatus is improved according to the invention by interrupted inclined walls of the aftersettling compartments to form such inlet openings, the wall parts thus formed being staggered at the inlet openings to screen them from rising gas so that this cannot enter the aftersettling compartments, by one such inclined wall extending downwardly past the opposite one to form an outlet opening for the aftersettling compartments screened against the entry of gas into them, by simple gas collecting hoods, a sludge discharge pipe below the level of the water in such compartments and by removable aftersettling compartments easily replaceable and loosely supported on supporting edges of the reactor tank.
