Abstract: Purification plant (A) for treatment and/or purification of water, preferably wastewater or drinking water, preferably for removal of inorganic or organic, preferably organic based impurities, comprises (i) at least one counter-flow filter device (1), preferably counter-flow adsorption filter column, and (ii) at least one regeneration device (RV), or (ia), at least one counter-flow filter device, (iia) optionally at least one drying- and/or dehumidifying device (T1, T2, T3), (iiia) at least one regeneration and/or desorption device, and (iva) optionally at least one humidifying device. Purification plant (A) for treatment and/or purification of water, preferably wastewater or drinking water , preferably for adsorptive removal of inorganic or organic, preferably organic based impurities, e.g. trace elements and/or micro-pollutants, comprises (i) at least one counter-flow filter device (1), preferably counter-flow adsorption filter column for treatment and/or purification of water and for continuously introducing, storing and supplying at least one particulate adsorbent material, and (ii) at least one regeneration device (RV) for continuous sampling the adsorbent material loaded with impurities from the counter-flow filter device, regeneration and/or recycling of adsorbent material loaded with impurities and re-supply of regenerated, unloaded and/or fresh adsorbent material in the counter-flow filter device or (ia), at least one counter-flow filter device, (iia) optionally at least one drying and/or dehumidifying device (T1, T2, T3) for drying and/or dehumidification of the adsorbent material loaded with impurities, (iiia) at least one regeneration- and/or desorption device for the regeneration of adsorbent material loaded with the impurities and/or to provide the regenerated, unloaded and/or fresh adsorbent material, (iva) optionally at least one humidifying device for the humidification of regenerated, unloaded and/or fresh adsorbent material. The regeneration device for continuous regeneration and reuse of the adsorbent material is connected to the counter-flow filter device such that the water, which is to be treated and/or purified (AW), and the adsorbent material in the operation- and/or application state of the plant are led in a counter-flow manner and/or opposite to each other in the counter-flow filter device. The water, which is to be treated and/or purified, and the adsorbent material in the operation- and/or application state of the plant are contacted with each other. The drying- and/or dehumidifying device is arranged downstream to the counter-flow filter device, relative to the transport direction of the adsorbent material. The regeneration and/or desorption device is arranged downstream to the counter-flow filter device and/or downstream to the drying- and/or dehumidifying device. The regeneration and/or desorption device is arranged upstream to the counter-flow filter device, relative to the transport direction of the adsorbent material. The humidifying device is arranged downstream to the regeneration and/or desorption device. The humidifying device is arranged upstream to the counter-flow filter device, respectively relative to the transport direction of the adsorbent material. The counter-flow filter device comprises at least one housing. The housing has at least one adsorption and/or counter-flow zone, at least one water inlet portion and at least one water outlet portion. The adsorption and/or counter-flow zone is fluidically arranged between the water inlet portion and the water outlet portion. The adsorption and/or counter-flow zone is arranged downstream to the water inlet portion and upstream to the water outlet portion, relative to the flow direction of the water. The water inlet portion comprises at least one adsorbent material outlet. The water outlet portion comprises at least one adsorbent material inlet. An independent claim is also included for the counter-flow filter device, preferably counter-flow adsorption filter column.
