A water conditioning system for evaporative cooling systems reduces operating costs and microbial contamination by introducing positively charged copper-silver ions into water used as a working fluid. Some of the recirculating water is also passed through a magnetic conditioner to increase its conductivity. By concentrating the total dissolved solids (TDS) in a portion of the water to be expelled, the remaining system water plus new make-up water added contains far lower TDS, reducing health risks, maintenance costs, corrosion, and scaling, and extending service life of replaceable filter elements and system machinery. Recovering non-chemically treated cooling tower bleed water with commercial scale nanofiltration water polishing equipment and returning that polished water back to the cooling tower water basin reduces the make-up water required, and may achieve 70% or greater reduction in sewer fees for tower bleed water, along with increased cycles of concentration further reducing requirement for make-up water.

A device for generating a disinfectant solution based on metal and water atoms , including at least one sealable enclosure, where at least one electrode is installed. The sealable enclosure further includes an inlet and an outlet. The device also includes an energy source that may be in contact with the fluid, or may be insulated from the fluid. Thus, the energy source may be made available inside the sealable enclosure or on the outside the sealable enclosure, or both. The device enables the rapid production of a disinfectant solution based on a mixture of fluid such as water and biocidal metal atoms such as silver atoms with increased antibacterial, virucidal and fungicidal properties.

An exemplary embodiment of the present invention provides a system for disinfecting a fluid. The system can comprise: a cylindrically-shaped outer electrode defining an internal cavity; a center electrode positioned within the internal cavity, the center electrode extending along at least a portion of a longitudinal axis of the outer electrode; an inlet positioned proximate a first end of the outer electrode and configured to allow a fluid to pass from an area external to the internal cavity into the internal cavity; and an outlet positioned proximate a second end of the outer electrode and configured to allow the fluid to pass from the internal cavity into an area external to the internal cavity. The outer electrode and the center electrode can comprise at least one metal selected from the group consisting of copper, silver, and zinc.

A liquid desalination system is disclosed. The liquid desalination system includes a feed line having an inlet to receive liquid and an outlet to discharge the liquid. The liquid desalination system includes a magnet coupled to the feed line, the magnet to generate an oscillating magnetic field within the feed line and in opposition to the feed water flow. The removal of targeted ions can be achieved by manipulating the frequency and rate of the generated electromagnetic waves. The generated electromagnetic waves can be tuned to weaken the hydration bonds of that specific ion and facilitate its removal. The liquid desalination system generates an electric field across the feed line to enable the liquid to flow through the electric field. The electric field may attract sodium ions to a positive electrode and may attract chloride ions to a negative electrode, to desalinate the liquid in the feed line.
