ABSTRACT:
An apparatus for purification of waste water includes an upright adsorber filled with inorganic granular adsorption material flowing in downward direction through the adsorber while waste water is fed in upward direction therethrough. The adsorber has a frustoconical outlet portion in which an inlet cone, having a perforated upwardly tapering wall, is provided into which the waste water is fed to assure a substantially even distribution of the waste water in the column of granular adsorption material during the upward flow of the waste water through the adsorber.
