Plant for the production of monochloramine and process thereof
First Claim
1. A process for the production of monochloramine, comprising:
- drawing a portion of water for a user and exclusively using said portion for preparing a monochloramine solution;
subjecting the portion for preparing the monochloramine solution to a treatment on an osmotized membrane and obtaining osmotized water,making said osmotized water react with reagents in a reactor, said reactor comprising a base and extending in an axial direction from said base, wherein the reagents are introduced in said axial direction of the reactor while the osmotized water is introduced on a plane parallel to the base of the reactor, in non-radial direction, and wherein said osmotized water is made to react with the reagents, simultaneously with the introduction of the osmotized water into the reactor;
introducing a reagent B, comprising an ammonium solution in salt form, through an orifice;
introducing a reagent A, comprising stabilized sodium hypochlorite, through another orifice, after introduction of the reagent B;
the osmotized water being continuously introduced into the reactor during introduction of each reagent,measuring pH of pure monochloramine solution produced by the reaction and verifying that said value falls within a range between 8-12;
discharging the solution produced in the reactor towards a storage tank after verifying that the pH is within the range of 8-12, 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.
