PLANT FOR THE PRODUCTION OF MONOCHLORAMINE AND PROCESS THEREOF
First Claim
1. Process for the production of monochloramine characterized in that it provides for:
- drawing a portion of water intended for a user (U1 . . . Un) and exclusively using said portion for preparing a monochloramine solution;
subjecting the portion intended for preparing the monochloramine solution to a treatment on osmotized membrane and obtaining osmotized water,making said osmotized water react with reagents (A, B) in a reactor (1) and wherein the entrance of the reagents (A, B) is in the same axial direction as the reactor (1) while the entrance (C) of the osmotized water is on a plane parallel to the base of the reactor, in non-radial direction, and wherein said reaction provides for, simultaneously with the entrance of the osmotized water in the reactor (1);
introduction of the reagent (B) comprising an ammonium solution in salt form, through an orifice (B);
once a defined time has elapsed or a preset level has been reached,introduction of the reagent (A), comprising stabilized sodium hypochlorite, through a third orifice (A);
in said step, osmotized water continues to flow into in the reactor (1);
introduction of osmotized water in the reactor (1) until the final level is reached,measurement of the pH of the pure monochloramine solution produced and verification that said value falls within a range between 8-12;
in positive case,discharge of the solution produced in the reactor (1) towards a storage tank (12), rendering the monochloramine produced by the reaction available for use.

Abstract
A process for the production of monochloramine characterized in that it provides for drawing a portion of water intended for the user and exclusively using the portion for preparing the monochloramine solution. The portion intended for the reaction of formation of monochloramine is subjected to a treatment on osmotic membrane, obtaining osmotized water. Subsequently, there is the reaction of the water with reagents in a reactor. In the reaction step, inside the reactor, the osmotized water enters from a first orifice (C) via a solenoid valve with micrometric regulation (EV1). Inside the same reactor, the base chemical products enter via the respective orifices A and B. The base chemical products enter due to the action of metering pumps (e.g. peristaltic pumps). The system is managed by PLC.
