Abstract
Apparatus for purification of waste water includes an upright adsorber filled with active carbon passing in downward direction through the adsorber while waste water flows in upward direction therethrough. A distributing arrangement is produced at the region of the lower end of the adsorber, into which waste water is fed, and constructed to assure a substantial even distribution of the waste water during its upward flow through the carbon column. A regulating arrangement is provided to regulate the flow of the carbon through the adsorber in dependence on the concentration of the organic contaminants adsorbed by the carbon.
