- Such an installation is in particular intended for cleaning mechanical or other parts.
- This installation comprises, in a manner known per se, a unit 1 for washing the parts in which the cleaning fluid is loaded with organic matter in contact with the parts and a unit 2 for treatment in which living microorganisms biologically degrade the organic material contained in the fluid from the washing unit 1. It is obvious that by room, we mean any type of object.
- At least part of the cleaning fluid is thus caused to circulate in loop or closed circuit between the washing unit 1 and the processing unit 2.
- loop circuit is meant a circuit which allows a circulation of at least part of the fluid from the washing unit 1 to the treatment unit 2 on the one hand and from the unit 2 to the unit 1 on the other hand to allow re-routing at least part of the fluid from unit 2 to unit 1.
- the cleaning fluid can be reused for the washing operation.
- the washing operation can be carried out in the form of a bath inside the washing unit 1 or by spraying cleaning fluid onto the surface of the parts. It is this second case which was chosen in the embodiment shown in FIG. 1.
- this installation further comprises, on the fluid circulation circuit, means 12 for at least partial sterilization of the microorganisms contained in at least part of the cleaning fluid.
- These means 12 for sterilizing the cleaning fluid are preferably means for sterilization by physical means capable of producing heat and / or radiation and / or ultraviolet rays, and / or by chemical means for a bactericidal action and / or bacteriostatic on microorganisms contained in the cleaning fluid.
- these sterilization means can be constituted by a UV lamp placed on the fluid circulation circuit, in particular on a pipe 4 for channeling the fluid which extends for example in the connection zone between the washing unit 1 and the treatment unit 2, this connection zone allowing circulation of the cleaning fluid from the unit treatment towards the washing unit 1.

- This filter material 3 also contains nutrients for microorganisms. These nutrients are preferably constituted by sources other than carbon sources and are preferably still insoluble, or poorly soluble, in the cleaning fluid. This constructive solution promotes the immobilization of microorganisms on their support so that very few microorganisms are caused to detach from the support 3 and to circulate in the fluid. Nutrient sources can include phosphorus, nitrogen, oxygen, sulfur, magnesium, potassium, calcium, iron, manganese and other trace elements.
