Activated carbon contains a maze of tiny pores with sizes ranging from 500-1000 nm and a surface area of about 1000 square meters per gram. The nature of this surface allows adsorption of organic impurities from the water and catalytic decomposition of free chlorine and, more slowly, chloramines.
It is applied in:
- Pre-treatment cartridges
- Composite Vent filters
- Final Purification cartridges
How does it work?
The large surface area of the activated carbon means that organic compounds adsorb to the surface through ionic, polar and Van der Waals forces. Activated carbon is typically used in combination with other technologies within the water purification process and the use of this needs to be kept into consideration for product design. One of the main benefits of activated carbons in the pre-treatment process is to remove any chlorine or chloramine
