Central control valve adapter (3) for a system (10) for treating a filtrate (W; W1, W2), • with the system (10), which has a pressure vessel (1) which has a container connection (1a) with an internal thread on the head, • with the container connection (1a), which on the inside of the internal thread has an internal passage leading to a head space (1e) of the pressure container (1), • with the pressure vessel (1), which is filled from a footwell (1c) to the free headspace (1e) with a gravel support layer (1b) which carries a filter aid material (1b *), • with a central control valve (2) assigned to the pressure vessel (1), the at least one central control valve inlet (2a) for supplying a filtrate to be treated (W1) into the pressure vessel (1) and a central control valve outlet (2b) for discharge a treated filtrate (W2) from the pressure vessel (1), • with the central control valve (2), which is set up in such a way that it controls at least one first fluid path (I) assigned to the filtrate (W1) to be treated and a second fluid path (II) assigned to the treated filtrate (W2), • with the central control valve (2), which has an external thread on its side facing the pressure vessel (1), whereby the first and second fluid paths (I, II) are each positively guided via an internal area in the external thread and furthermore via the internal passage in the container connection ( 1a) are in fluid communication with an interior of the pressure vessel (1), • and with an extraction pipe (1d), which extends from the footwell (1c) via the inner passage in the container connection (1a) into the central control valve (2), an inner pipe passage of the extraction pipe (1d) forming an integral section of the second fluid path (II ) for the treated filtrate (W2), characterized in that that a central control valve adapter (3) is provided, • which is connected on the one hand to the external thread of the central control valve (2) via an adapter internal thread (3a) and on the other hand to the internal thread of the container connection (1a) via a connector with an adapter external thread (3b), • which has a central passage opening (3c) through which the extraction tube (1d) is passed, • which has at least one outer channel (3h; 3h.1, 3h.2, 3h.3) radially outside the central passage opening (3c), which has an integral and fluid-accessible section of the first fluid path (I) for the filtrate to be treated ( W1) forms / forms and opens out into the head space (1e), • which radially outside of the central passage opening (3c) has at least one inlet channel (3f) for a first treatment medium (M1) to be fed, which on the one hand into the head space (1e) and on the other hand into a first connection opening (3e) between the adapter internal thread (3a ) and adapter external thread (3b) opens into the vicinity of the central control valve adapter (3), • and which has at least one second connection opening (3g) for a first treatment medium (M1 *) to be discharged and / or a second treatment medium (M2) to be supplied, the second connection opening (3g) on the one hand with the at least one outer channel (3h; 3h.1 , 3h.2, 3h.3) is fluidly connected and on the other hand opens out between the adapter internal thread (3a) and adapter external thread (3b) in the vicinity of the central control valve adapter (3).
