KDF85 Filter Media
General Description
KDF85 media (or Kinetic Degradation Fluxion Media), is a chemical compound used in water filtration applications. It Removes or reduces iron and hydrogen sulfide from municipal or other water supplies. Also controls scale, bacteria and algae. KDF85 is often used along with activated carbon to maximise the filters efficiency. Generally KDF85 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. KDF 85 water treatment media also controls scale, bacteria, fungi, and algae.
2. KDF 85 process media can remove up to 99% of water-soluble lead, mercury, nickel, chromium, and more
3. KDF 85 media controls the buildup of bacteria, algae, fungi and scale
4. KDF 85 works great for municipal or well water.
