Regardless of the system chosen, Soft Rain considers the recovery and then the reuse of the nanotechnological solution by reintroducing it into the tunnel pre-treatment process.
The overspray of the excess nanotechnological solution is conveyed into a tank intended for recovery, positioned under the application module of the tunnel.
The nanotechnological solution collected inside the tank is relaunched by a pump dedicated to a tank of the pre-treatment tunnel. This operation allows to maximize the consumption of the aqueous solutions, allocating them to one of the stages of the pre-treatment process where it is allowed to use them, mixing them with the solution already present in the tank.
