Abstract
A method for cleaning a spraying circuit, in particular of paint, and for treating the chemical effluents generated includes a first rinsing of the paint circuit using a predetermined first volume of treated effluent, a second rinsing of the paint circuit using a predetermined second volume of ecosolvent and a third rinsing of the paint circuit using a predetermined third volume of treated effluent, so as to save on the consumption of water from the network by recycling the treated effluent to clean and rinse the paint circuit.
