KDF55 Filter Media

General Description

KDF55 media (or Kinetic Degradation Fluxion Media), is a chemical compound used in water filtration applications. It is designed specifically for removing or reducing chlorine and water-soluble heavy metals. It controls scale, bacteria and algae, even in hot water. KDF55 is often used along with activated carbon to maximise the filters efficiency. Generally KDF is used in a purification system as a pre-filter, before another, finer stage of filtration, for example, reverse osmosis, deionisation and ion exchange systems.

Structure

KDF water filtration media is a high-purity alloy of both copper and zinc, used in a flaked or granulated particulate form. Usually appearing gold or brass in colour.

 

Application

1.High-Efficiently remove chlorine, pesticides, organic matter, rust, unpleasant taste and odour.

2.Efficiently kill algae and fungi, control bacteria growth.

3.Efficiently removes soluble heavy metal ions in water such as Pb2+ , Cd2+ ,Cr6+ , As3+ , Hg2+ , Mn2+ , Ni2+ , Al3+ , Fe3+ etc.

4.Efficiently remove hydrogen sulfide,calcium and other organic compounds.
