CLAIMS

1. A transportable modular system (1) for emergency treatment of water polluted by liquid hydrocarbon spillage, comprising at least a first containerized treatment module (3), comprising a container (5) in the form of a standard size intermodal container which houses a coalescence separator device (7), configured to operate an oil/water separation; a suction pipe (8) having a first end (11) connected to the coalescence separator device (7) and a second end (12) provided with an inlet (13) connected to at least one floating skimmer (14) ; a pump (15) positioned on the suction pipe (8) ; a water drain pipe (24) and an oil drain pipe (27), connected to a water outlet (23) and an oil outlet (25) , respectively, of the coalescence separator device (7) .

2. The system according to claim 1, wherein the coalescence separator device (7) is provided with coalescence surfaces immersed in a treatment tank (20) .

3. The system according to claim 2, wherein the coalescence separator device (7) is a coalescing plate separator device, and the coalescing surfaces are formed on a set (21) of coalescing plates.

4. The system according to one of the preceding claims, wherein the skimmer (14) is provided with floats (16) for floating on a water surface onto which it is placed .

5. The system according to one of the preceding claims, wherein the suction pipe (8) is a flexible pipe which can be unwound from the container (5) so as to extend, in use, out of the container (5) and overboard a vessel (2) on which the treatment module (3) is positioned, until it reaches, with said second end (12), a water surface on which the vessel (2) is placed.

6. The system according to one of the preceding claims, wherein the pump (15) is a volumetric pump.

7. The system according to one of the preceding claims, wherein the coalescence separator device (7) is provided with a recirculation system (30), comprising: a recirculation conduit (31) which branches off from the water drain pipe (24) and engages the suction pipe (8) ; a concentration meter (32) positioned along the water drain pipe (24) and configured to measure the oil concentration in the water stream exiting the coalescence separator device (7); a control unit (33) connected to the concentration meter (32) and to a three-way valve (34) positioned along the water drain pipe (24) and connected to the recirculation conduit (31) .

8. The system according to one of the preceding claims, wherein the coalescence separator device (7) is provided with a level alarm (35), which detects the level of the oil layer in the treatment tank (20) and provides an alarm signal when a preset level is exceeded.

9. The system according to one of the preceding claims, wherein the water drain pipe (24) and/or the oil drain pipe (27) are flexible pipes, or comprise at least respective portions consisting of flexible pipes, which can be unwound from the treatment module (3) .

10. The system according to one of the preceding claims, comprising at least one containerized storage module (4), comprising a second container (5) in the form of a standard size intermodal container which houses a tank (40) provided with an inlet (41) connectable, via a releasable joint, to the oil drain pipe (27) .
