ABSTRACT:
An apparatus for clarification of industrial sewage comprises a vertical cylindrical chamber for circulation of industrial sewage with a conical bottom secured to which are a branch pipe for feeding the polluted industrial sewage with flocculants, and a branch pipe for discharging the slurry. Secured outside of the cylindrical chamber at its upper edge is a circular trough for draining the purified sewage while inside the chamber are arranged partitions for settling of solid particles and at least one separating partition in the form of a body of revolution with holes for distributing polluted sewage over the volume of the chamber, said partition being installed axially in the central part of the chamber with its upper edge arranged level with the upper edge of the chamber. Installed above the separating partition is a pressuretight bell-shaped housing communication with an air rarefaction means.
