What is wood based activated carbon?
Wood based activated carbon is produced from selected types of wood and sawdust. This type of carbon is produced by either steam or phosphoric acid activation. Most pores in wood based carbon are in the meso and macro pore region which is ideal for decolorization of liquids and water.
Wood based activated carbon applications
Wood base carbon is primarily used in surface water and wastewater filters to remove organic impurities and to effectively remove larger molecular structures like MIB (2-Methylisoborneol) and Geosmin. Wood base phosphoric acid activation can yield carbon with a very high surface area, ranging from 1500-2500 m2/g. The product is available in granular, pelletized, or powder forms.
The significant difference between wood and carbon or coconut based activated carbon is the large pore size, making it suitable for macromolecules. Therefore, typical applications cover:
- Large active pharmaceutical ingredients (API)
- Purification of edible oils
- Sweeteners
- Starch
- Solvents
Wood based carbon is also common for the removal of colors in a variety of industries such as textile production.
Manufacturing and provided range by Mellifiq
Wood based activated carbon has two main production processes: steam activation similar to the production of coal and coconut based carbon, and phosphoric acid activation. The end product results in a specialized carbon type with high porosity, adsorption capacity for large molecules, high permeability and purity.
