The Redox media filter bed is made up of very fine alloy particles which have excellent mechanical filtration properties. Particulate matter is trapped in the filter bed and many dissolved pollutants are converted by oxidation. This filter therefore offers a very versatile media for pollutant removal which is very durable. The bed is also resistant to microbiological contamination. Maintenance is simple, the filter requires backwashing every 12-14 days, the filter media lasts 2-3 years.

99% of chlorine in water is removed by oxidation reduction, a process in which chlorine gas is electrochemically reduced into water soluble ions.

Redox media removes up to 98% of water soluble cations of harmful contaminates like lead, mercury, copper, nickel, chromium, cadmium, arsenic, antimony, cobalt and most other dissolved heavy metals - see table overleaf. Soluble metals are reduced into insoluble metal ions and metallic contaminants are bonded to the redox alloy.

The disruption of electron transport causes a cascade of cellular damage.
Direct electrochemical contact.
The formation of hydroxyl radicals and hydrogen peroxide interferes with a microorganism's ability to function.

The redox alloy media alters the morphology of the insoluble calcium magnesium carbonate and the sulfate crystals, found in water into smaller evenly shaped rounded grains. These form a powdery compound that will not adhere to metallic surfaces and can be easily removed by filtration.

The Redox filter media combines the dissolved oxygen and soluble ferrous iron forming insoluble ferric hydroxide and ferric oxide which is then catalytically removed.
