  Nano-metal clusters media

water treatment media Nano-KDF



· Sole in the world
· Patented products 
· 5-20times of KDF's effect
· Ideal substitute of KDF media
· Novel water purification media





Water purification media Nano-KDF invented by Dr. Xiaorong Huang is a novel water purification media which made from millions of nano-metal clusters on porous inorganic material, and its specific surface and porosity is more than 100 times of KDF media's. NMC formed in innumerous micro primary cells has a very strong redox (reduction- oxidation) ability to reduce the heavy metal ions of Pb2+, Cd2+, Cr6+, As3+, residual chlorine into insoluble metal and Cl-, and to oxidize organics in water into harmless components. The growth and breeding of bacteria and virus are inhibited and eliminated because of shifting of oxidation/reduction potential. NMC media is a very high efficient water purification media over activated carbon and KDF media.





·Highly efficently removes residual chlorine and disinfection by-product.
·Efficiently removes soluble heavy metal ions in water such as Pb2+, Cd2+, Cr6+, As3+, etc.
·Decreasing the concentration of organic pollutants and F-, Hg+, NH3, NO2- in water.
·Micro-organisms growth and reproduction can be inhibited and eliminated.


NMC(Nano-KDF) vs KDF





Patented product ( ZL06100367.5) of nano-metal clusters water purification material (NMC) are media with high specific surface and porosity 100 times of KDF55s , can simultaneously remove soluble heavy metal ions of Pb, Cd, Cr, As, etc., free chlorine, and organics in water.

 NMC media supplement or replace existing technologies, such as KDF and Activated carbon, which successfully overcome KDFs disadvantage that clumped easily and filtration resistance become bigger and bigger with the use time gone. Moreover, the growth and breeding of bacteria are inhibited and eliminated because of shifting of oxidation/reduction potential, this feature is much better than Activated carbon.

 NMC can dramatically increase removal of heavy metals, free chlorine, extend water systems life, reduce microorganisms.

1, Removal of free chlorine is 5-10 times of KDF55 at same flow rate.

2, 95% removal of free chlorine can keep during Water purifying capacities of 100-500L/g(depending on the water quality)

3, Microorganisms growth and reproduction can be inhibited.

4, Pb, Cd, Cr , As ion can be removed.     


 Safety evaluation test:

  Pureeasy's NMC media has passed the test of “Safety evaluation of Protective Materials in Drinking Water System" by CDC* of GD province. The test shows all items such as colority, turbidity, taste and odour, visible substance, PH, TDS, COD, volatile phenol, Fe, Mn, Cu, Zn, As, Cd, Cr(6+), Al, Pb, Hg, Ag, CHCl3, CHCl4, F-, NO3--N, radioactivity( total α, total β) meet the Chinese safety requirements of materials in drinking water system.
