Iron Powder and Foam Method

New Iron Powder Mixing Method with Space-saving and No Sludge generation

Iron powder mixing methods are used to purify highly concentrated VOCs pollution quickly.
Unfortunately, the disadvantages of this methods include the requirement of a large plant and the generation of a lots of sludge. Our new foam method; however, uses foam instead of water to resolve the problems with conventional techniques.

Foam Method Benefits

With conventional method, the ground surface turns into mud because of the large amounts of water supplied to the ground. With the foam method, the amount of water is significantly reduced so that the impact to the ground is minimized.

Conventional method Foam method
Required water 135m3 9m3
Sludge 50m3 0m3
Plant yard 20m x 20m 10m x 5m

*These values are per internal comparisons. These values can vary depending on the level of pollution and actual conditions.
Calculation conditions: Size of contaminated soil: 10 m x 10 m x 5 m = 500 m3 Iron powder ratio: 5% by weight, Amount of iron powder: 45 t
