## Abstract

A system for the polishing treatment of inner walls of aquatic enclosures includes at least one tank of abrasive mixture and at least one surface treatment head which communicates fluidically with the tank of abrasive mixture, a mover allowing the treatment head to be moved along the wall to be treated, and a supply allowing the treatment head to be supplied with a substantially continuous flow of abrasive mixture.

## Claims

### Claim 1

A system for polishing internal walls of aquatic enclosures, comprising:
at least one abrasive mixture tank and:,
at least one surface treatment head in fluid communication with the abrasive mixture tank;
a mover for moving the treatment head along one of the internal walls; and
a supply for supplying the abrasive mixture to the at least one treatment head with a substantially continuous flow,
wherein the at least one treatment head comprises a containment chamber, a treatment disc rotatably arranged in the containment chamber, and a hollow rotating and feeding shaft connected to the treatment disc and to the supply,
wherein the treatment disc is connected to a treatment disc motor, and
wherein the treatment disc carries a friction foam.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the containment chamber comprises at least one outlet orifice in fluid communication with at least one recovered mixture tank.

### Claim 3 (depends on 1)

The system according to claim 1, wherein the movers comprise at least one horizontal rail and a vertical rail.

### Claim 4 (depends on 3)

The system according to claim 3, wherein at least one of the rails is movably mounted.

### Claim 5 (depends on 1)

The system according to claim 1, wherein the at least one treatment head includes at least one treatment head thrust propeller, positioned substantially opposite to the containment chamber.

### Claim 6 (depends on 1)

The system according to claim 1, further comprising a circuit for recirculating the abrasive mixture.

### Claim 7

A method for by polishing internal walls of aquatic enclosures, comprising:
feeding a surface treatment head with an abrasive mixture;
receiving the abrasive mixture;
transmitting the abrasive mixture into a containment chamber of the surface treatment head;
impregnating a treatment disc provided in the containment chamber with the received abrasive mixture;
rotating a treatment disc;
treating one of the internal walls by friction of the rotating treatment disc against the wall;
recovering the abrasive mixture after use; and
moving the surface treatment head.

### Claim 8 (depends on 7)

The method according to claim 7, wherein the distribution of abrasive mixture is carried out in a continuous flow.

### Claim 9 (depends on 7)

The method according to claim 7, wherein the recovered abrasive mixture is used in several treatment cycles.

### Claim 10 (depends on 7)

The method according to claim 7, wherein a flow of the abrasive mixture is controlled such that a pressure exerted within the containment chamber is lower than an external pressure of an ambient medium supplemented with a thrust of the propeller exerted on the containment chamber.

### Claim 11 (depends on 7)

The method according to claim 7, wherein a pressure differential is adjusted to facilitate movement of the surface treatment head on the wall by limiting friction at all levels of working depth of the surface treatment head while ensuring the containment of the abrasive mixture in the containment chamber.

### Claim 12 (depends on 1)

The system according to claim 1, wherein the at least one treatment head includes a plurality of treatment head thrust propellers disposed in parallel.
