METHOD AND APPARATUS FOR THE PRODUCTION AND DELIVERY OF MONOCHLORAMINE INTO WATER STREAMS
First Claim
1. A method for treating water streams comprising:
- providing a water stream to be treated,providing a mixing chamber in fluid communication with a potable water source, said mixing chamber configured to allow at least a portion of said potable water to have bubble froth turbulence,injecting a chlorine source into said mixing chamber,injecting an ammonia source into said mixing chamberforming a selected level of monochloramine from said nitrogen source and said chlorine source in said potable water; and
injecting said monochloramine containing water into said water stream to be treated.

Abstract
Monochloramine is efficiently manufactured by introducing controlled quantities of an ammonia source and a chlorine source in a small side-stream of water in a small diameter pipe under turbulent flow conditions. The ammonia source and chlorine source can be injected in either order and are separated by a sufficient distance to ensure that the first chemical is adequately diffused throughout the water prior to the injection of the second chemical. A sufficient length of a mixing chamber insures that turbulent flow is maintained for a length of time sufficient to thoroughly mix the two chemicals to produce monochloramine. This mixing technique allows for the manufacture of high concentrations of monochloramine at atmospheric pressure without off gassing.

12. An apparatus for the production of monochloramine for the treatment of water streams comprising:
-
a mixing chamber in fluid communication with a potable water source said mixing chamber configured to allow at least a portion of said potable water to have bubble froth turbulence, a means for injecting a chlorine source into said mixing chamber, a means for injecting an ammonia source into said mixing chamber, wherein a selected level of monochloramine is formed from said nitrogen source and said chlorine source combined in said mixing chamber containing potable water having said bubble froth turbulence; and an injection chamber in fluid communication with said mixing chamber and in further fluid communication with said water stream to be treated. - View Dependent Claims (13, 14, 15, 16, 17)
