Abstract: Suspended particles are sepd. from water, sewage, and aq. industrial effluents by the addn. of flocculating agents and the subsequent sepn. of the flocks and the matter absorbed by them, by sedimentation and filtration. A buoyant filter layer is used, beneath which the flocks form, densify, and can be drained away. The filter layer is a granular material of density 0.9 g./cm.3, such as polyethylene, polystyrene, cellular concrete etc., and the filter has two zones, an upper with 0.8 to 1.5 mm. dia. granules, and a lower with 2 to 4 mm. dia. granules. Compact installation is obtd. as compared with plants using gravel filters. Less rinsing water is necessary for washing out the filter layer.

Abstract: The invention concerns a counter-current adsorption filter for the treatment of liquids, with different adsorbents which require different regenerating agents, in which loading of the different adsorbents is effected in a stream of liquid flowing upwards and regeneration of the different loaded adsorbents with the different regenerating agents is effected in a stream of liquid flowing downwards, the inside of which filter is subdivided, by horizontal devices which are permeable to liquid, into a number of chambers corresponding to the number of different adsorbents to be used; in which the adsorbents which are regenerated with different regenerating agents are present in adjacent chambers; the chambers - with the exception of the topmost chamber of the filter - are equipped with a liquid drainage system which is located below the device which is permeable to liquid and forms the upper boundary of the chamber, and which is embedded in a layer of inert material; and in which the individual chambers are filled with a certain amount of adsorbent. The invention furthermore concerns a process for the operation of this letter.
