How it works

Bacteria and fungi, commonly found in aqueous industrial fluids, pose serious threats to productivity and health. They also produce foul odors, most often from hydrogen sulfide—a byproduct of bacteria colonies characterized by its “rotten egg” smell. Predator Bacteria Filter is an innovative and economical method of controlling these microorganisms and the odors they generate.

Predator Bacteria Filter cartridges consist of high-purity copper-zinc fibers tightly wound within a stainless steel tube. In an electrolytic solution (water), the dissimilar metals of the copper-zinc alloy undergo a natural electrochemical reaction, also known as an oxidation-reduction reaction.

During oxidation-reduction (or redox) reactions, electrons are transferred from one molecule to another. Molecules that lose an electron are said to be oxidized, while molecules that gain an electron are reduced. In the case of Predator, hydrogen sulfide is reduced to cupric sulfide. This insoluble molecule attaches to the strands of the filter element and is easily removed with a clean water rinse.

In the presence of water, copper and zinc create a galvanic cell. This cell produces an electric charge lethal to micro-organisms. Bacteria and fungi (including yeasts and molds) cannot function in fluid passing through a Predator filter cartridge.
