High-purity copper-zinc redox media consistently remove 99% of free chlorine by electrochemically reducing dissolved
chlorine gas to water-soluble chloride ions.
- KDF process medium are being used to complement or replace activated carbon filters,
- removing up to 95% of the chlorine when treating municipal water.
- KDF media pretreatment of granular activated carbon also extends the carbon's life and limits bacteria growth in the bed.
KDF Process Media are used for a variety of pretreatment, primary water treatment, and wastewater treatment processes.
They are generally used in place of, or in conjunction with, granular activated carbon filters, even carbon block or inline filters.
KDF water filter media extend the life of granular activated carbon (GAC) while protecting the carbon bed against fouling by bacterial growth.
Our Media are also used to replace silver-impregnated systems. Silver is toxic,
KDF Process Media are not. Silver must be registered with the EPA as a toxic pesticide,
KDF Process Media do not. By the way, silver is more expensive than KDF Process Media.
We can explain redox (oxidation reduction process) like this:
KDF Fluid Treatmentâ€™s unique combination of copper and zinc creates an electro-chemical reaction.
During this reaction, electrons are transferred between molecules, and new elements are created.
harmful contaminants are changed into harmless components. Free chlorine, for instance, is changed into benign, water-soluble chloride,
which is then carried harmlessly through the water supply.
Similarly, some heavy metals such as copper, lead, mercury and others,
react to plate out onto the mediumâ€™s surface, thus being effectively removed from the water supply.
PLEASE NOTE THE MEDIA COULD MIXED TOGETHER, IT DOES NOT AFFECT THE WORKING OF THE working of the filter.

Typical Rejection Percentages of
Thin Film Composite (TFC) Reverse Osmosis Membranes
Below are the typical rejection (removal) percentages of a standard thin film (TFC) reverse osmosis membrane. These are averages based on experience and are generally accepted within the industry. They are not a guarantee of performance. Actual rejection can vary according to the chemistry of the water, temperature, pressure, pH and other factors.
Estimated Reverse Osmosis Rejection Percentages
The reverse osmosis process uses a semi-permeable membrane to reject a wide variety of impurities. Here is a partial list.
Aluminum 97-98% Nickel 97-99% Ammonium 85-95% Nitrate 93-96% Arsenic 94-96% Phosphate 99+% Bacteria 99+% Polyphosphate 98-99% Bicarbonate 95-96% Potassium 92% Boron 50-70% Pyrogen 99+% Bromide 93-96% Radioactivity 95-98% Cadmium 96-98% Radium 97% Calcium 96-98% Selenium 97% Chloride 94-95% Silica 85-90% Chromate 90-98% Silicate 95-97% Chromium 96-98% Silver 95-97% Copper 97-99% Sodium 92-98% Cyanide 90-95% Sulphate 99+% Ferrocyanide 98-99% Sulphite 96-98% Fluoride 94-96% Zinc 98-99% Iron 98-99% Lead 96-98% Insecticides 97% Magnesium 96-98% Detergents 97% Manganese 96-98% Herbicides 97% Mercury 96-98% Virus 99+% TDS (Total Dissolved Solids) 95-99% Hardness 93-97%
