To provide a recovery plant for surplus water paint in paint-spraying booths comprising a circuit of water circulating in the booth, wherein such problems with sedimenting water paint particles no longer arise, it is proposed that a volume flow of water circulating in the booth flow from the circuit of water circulating in the booth through a branch pipe to a preconcentration stage, that the preconcentration stage comprise a ring circuit with an ultrafiltration unit for continuously producing a preconcentrate in the ring circuit and a permeate which leaves the ring circuit, that the permeate flow into the circuit of water circulating in the booth and the preconcentrate into a final concentration stage, that the final concentration stage comprise a ring circuit with an ultrafiltration unit which increases the concentration of the preconcentrate in batches to the final concentrate and produces a permeate which flows into the circuit of water circulating in the booth.
