A station for localized surface treatment of an industrial workpiece to be treated comprising: - at least one treatment chamber formed by a cell or two half-cells , each cell or half-cell including positioning means and being suitable for delimiting a tight space between the walls of said cell or half-cell and the respective portion or face of the workpiece to be treated , the cell or each half-cell comprising a wall having an opening suitable for covering the corresponding portion or face of the workpiece to be treated , the opening of the cell or half-cell being delimited by a continuous sealing gasket ; - a plurality of storage vats each able to contain a treatment fluid; - a supply and emptying circuit of the treatment chamber connecting each storage vat to the treatment chamber so as to supply the treatment chamber with the respective treatment fluids; characterized in that : - the treatment station comprises a system for decreasing pressure with respect to the atmospheric pressure of the treatment chamber and the supply and emptying circuit allowing the supply, respectively the emptying, of the chamber owing, during said pressure decrease, to the suction of treatment fluid through the supply and emptying circuit from the storage vats to the treatment chamber , respectively, when the supply and emptying circuit is set to atmospheric pressure, owing to the return by gravity of the treatment fluid to the storage vats , which are located at a lower level than the treatment chamber ; - the tight space delimited between the walls of said cell or half-cell and a respective portion or face of the workpiece to be treated is ensured by a sealing gasket inflated with air at a pressure of between 0 and 5 bars, preferably between 1 and 2 bars, once the means for positioning the cell or each half-cell have positioned the latter at several tenths of a mm from the surface of the workpiece to be treated. - at least one treatment chamber formed by a cell or two half-cells , each cell or half-cell including positioning means and being suitable for delimiting a tight space between the walls of said cell or half-cell and the respective portion or face of the workpiece to be treated , the cell or each half-cell comprising a wall having an opening suitable for covering the corresponding portion or face of the workpiece to be treated , the opening of the cell or half-cell being delimited by a continuous sealing gasket ; - a plurality of storage vats each able to contain a treatment fluid; - a supply and emptying circuit of the treatment chamber connecting each storage vat to the treatment chamber so as to supply the treatment chamber with the respective treatment fluids; - the treatment station comprises a system for decreasing pressure with respect to the atmospheric pressure of the treatment chamber and the supply and emptying circuit allowing the supply, respectively the emptying, of the chamber owing, during said pressure decrease, to the suction of treatment fluid through the supply and emptying circuit from the storage vats to the treatment chamber , respectively, when the supply and emptying circuit is set to atmospheric pressure, owing to the return by gravity of the treatment fluid to the storage vats , which are located at a lower level than the treatment chamber ; - the tight space delimited between the walls of said cell or half-cell and a respective portion or face of the workpiece to be treated is ensured by a sealing gasket inflated with air at a pressure of between 0 and 5 bars, preferably between 1 and 2 bars, once the means for positioning the cell or each half-cell have positioned the latter at several tenths of a mm from the surface of the workpiece to be treated. <EOS>
