CUZN WATER SYSTEMS INC.

CuZn media functions by catalytic action, using the age-old redox (reduction-oxidation) principle of dissimilar metals. Water containing dissolved oxygen, minerals, and organic materials enters a bed of the copper-zinc alloy, with the copper becoming the cathode and the zinc becoming the anode.

The space between each granule of alloy in the media bed becomes an electrolytic cell. The water and contaminants act as electrolytes.

As contaminants and oxygen pass through, a reaction takes place, causing zinc hydroxides and copper hydroxides to form in controlled amounts. These controlled releases of copper and zinc oxides (chelatable by the body) are carried into the filtered water and provide hostile conditions for algae, fungus, and bacteria growth.

Copper-zinc can be used alone or in concert with traditional treatment processes (such as carbon and reverse osmosis) for a synergistic blend of media. Copper-zinc assists traditional treatment by extending the life of carbon or reverse osmosis membranes, by maintaining a bacteriostatic environment inside the filter, and by leaving a residual of copper and zinc hydroxides in the treated water to discourage bacterial growth.

With a lifespan of 10 to 20 times that of carbon, copper-zinc is the most efficient, longest lasting, and lowest maintenance filtration media on the market. It removes the weak link in most water treatment systems: the monitoring and maintenance and component replacement required by these systems.

CuZn systems perform better because the compact, dense copper-zinc alloy has no pores that plug up, is not soft like carbon, has no membranes to replace, remains bacteriostatic, and can be easily backwashed for years of use.
