Abstract

A water cooling/recirculating management system, including: a controller; a fluid displacement pump; a centrifugal separator; a germicide generator; a primary side stream magnetic field generator; an optional continuous, real time corrosion monitoring and reporting system; and a continuous, real time biofilm monitoring and reporting system.

Claims (24)

1. A system, comprising:

a controller, wherein the controller is in communication with a fluid displacement pump, a centrifugal separator purge valve, and a germicide generator;

a fluid displacement pump, wherein the fluid displacement pump extracts water from a main stream basin, prefilters the extracted water, and displaces the extracted water through a closed-circuit side stream;

a centrifugal separator, wherein the centrifugal separator includes an inlet, an outlet, a solids collection chamber, and a purge valve that releases solids collected in the collection chamber;

a germicide generator, wherein the germicide generator comprises at least one electrode fabricated from approximately 93 percent copper and approximately 7 percent silver;

a primary side stream magnetic field generator, wherein the primary side stream magnetic field generator comprises at least one permanent ceramic magnet having side-to-side polarity mounted to a non-ferrous pipe with a south pole facing inward toward water;

a continuous, real time corrosion monitoring and reporting system; and

a continuous, real time biofilm monitoring and reporting system, wherein the biofilm monitoring system measures cathodic current density on a surface of a probe continuously and in real time.

2. A system, comprising:

a controller in electrical communication with a fluid displacement pump, a centrifugal separator purge valve, and a germicide generator;

the fluid displacement pump that extracts water from a main stream basin through a closed-circuit side stream;

the centrifugal separator having a solids collection chamber with the purge valve;

the germicide generator comprising at least one electrode fabricated from approximately 93 percent copper and approximately 7 percent silver;

a primary side stream magnetic field generator comprising at least one permanent ceramic magnet;

a continuous, real time corrosion monitoring and reporting system that uses linear polarization resistance technique with harmonic distortion analysis; and

a continuous, real time biofilm monitoring and reporting system that measures cathodic current density on a stainless steel or titanium probe surface, wherein the controller operates the purge valve, controls the germicide generator in at least one of an off mode, continuous on mode, and non-continuous pulse mode, and receives real-time data from both monitoring systems.

3. A system, comprising:

a controller with programmable logic controller functionality;

a fluid displacement pump comprising a one to three horsepower pool pump with prefilter;

a centrifugal separator that removes particles down to 40 microns and contains no filter medium or moving parts;

a germicide generator comprising electrodes fabricated from approximately 93 percent copper and approximately 7 percent silver operating in a copper/silver ionization system;

a primary side stream magnetic field generator comprising permanent ceramic magnets with side-to-side polarity mounted to a non-ferrous pipe having a south pole facing inward toward water;

a continuous, real time corrosion monitoring and reporting system utilizing linear polarization resistance with harmonic distortion analysis and electrochemical noise measurement; and

a continuous, real time biofilm monitoring and reporting system measuring cathodic current density on a probe surface continuously, wherein the system eliminates chemical treatment costs, blowdown water, and provides up to 40% energy savings through physics-based water treatment.
