Micro 4 LS – Solubles-free granular activated carbon from coconut shells


Soluble-free activated carbon.

Granular coconut shell activated carbon free of soluble salts, for specific applications when the conductivity of a liquid should not increase.

Product images are demonstrative and may vary from the physical product.


Acid-washed activated carbon.

Raw material: Coconut shell.

Particle size range (mesh): 8×30, 12×40, 20×50.

Presentation: 25 kg bags, or 500 kg super bags.

pH: 6.0 to 8.0.

Coconut shell activated carbon tends to be microporous and adsorbs more efficiently the low molecular weight organic contaminants that are most present in well water.

All activated carbon of vegetable or mineral origin contains inorganic salts and elements, some of which are soluble in water. These come from the vegetable originating from coal. All vegetables contain minerals that remain in the product when the plant is carbonized.

Many people tend to confuse the term “solubles” with the term “ashes” in an erroneous way, since they are concepts that are linked to each other.

Ashes are all acid-soluble and acid-insoluble inorganic compounds or elements that are foreign to the material in question. Soluble is only the inorganic part soluble in acid, since every substance soluble in acid is soluble in water.


Purification processes that can be affected by small amounts of soluble salts, modifying parameters such as pH, conductivity, and color.
