Problems solved by technology

[0009] It would be desirable to provide scale control and water treatment compositions suitable for use in water distribution systems having enhanced effectiveness combined with extended effective shelf life (to provide, for example, reduced shipping weight, reduced storage capacity, and reduced size and reduced dosing equipment such as cost of pumps and valves), it should be understood, however, that increasing the concentration of chlorinated species tends to result in a faster rate of decomposition (and a faster loss of active ingredient concentration), thereby inhibiting the ability to simultaneously meet the above criteria

Embodiment Construction

[0027] Herein, methods are described for the preparation and use of novel mixed oxidant solutions exhibiting enhanced effectiveness and enhanced stability compared to existing solutions, which are particularly useful for water treatment and / or reduction of Sediments in water distribution and / or water recirculation systems. In contrast to existing solutions obtained by electrolysis of a brine solution in a flow-through cathodic compartment followed by electrolysis of a catholyte solution in a flow-through anode compartment (for example, as described in U.S. Pat. No. 8,366,939 Chemical solutions and commercially available from Blue Earth Labs, LLC, Las Vegas, Nevada, US Mixed oxidant solutions) In contrast, the various novel mixed oxidant solutions described herein advantageously comprise the process of passing at least one initial solution (i.e., comprising at least one of brine, hypochlorous acid, and sodium hypochlorite) through the An anolyte solution produced by an anodi...

Abstract

The invention relates to methods and stabilized compositions for reducing deposits in water systems. A stabilized mixed oxidant solution may be produced by flowing a starting solution (e.g., salt brine, hypochlorous acid, and / or sodium hypochlorite) through a flow-through electrochemical module including first and second passages separated by an ion permeable membrane while electric power is applied between an anode and cathode in electrical communication with the first and second passages, respectively. An initially acidic anolyte solution received from the first (anode) passage is stabilized by elevating pH to yield a stabilized mixed oxidant solution. Methods of using the mixed oxidant solution are further provided.

Description

technical field [0001] The present invention relates to a method and stabilizing composition for reducing sediment in water systems. More specifically, the present invention relates to a method for producing a mixed oxidizer solution comprising a plurality of different oxidizers, and a mixed oxidizer solution obtained by the method. Background technique [0002] Water typically includes organic matter, dissolved solids, and minerals that deposit fouling and films (eg, biofilms) on surfaces of potable water distribution pipes and equipment. The quality and flow of drinking water can be adversely affected by such fouling and membranes. Various cleaning and disinfecting agents can additionally leave film residues. The formation of these deposits can be effectively reduced, removed, or prevented using the methods and compositions described herein. [0003] Chlorine and chlorine-based disinfectants (including sodium hypochlorite, also known as liquid bleach) are widely used wo...
