Acid Wash GAC

Activated carbon is one of the most commonly used media for water and wastewater treatment. It’s multifunctional in use and has been considered a “scavenger medium” for its ability to dechlorinate and remove organics, colour, taste and odour. Dechlorination is essential prior to ion exchange and reverse-osmosis systems to prevent oxidation of the resin or membranes.

The acid-washed activated carbon mainly removes the impurities in the activated carbon, more of which are heavy metals. On the other hand, it is to adjust the PH value of the activated carbon are heavy metals. On the other hand, it is to adjust the PH value of the activated carbon.

Acid-washing activated carbon, as the name suggests, is activated carbon that has been acid-treated and washed. Acid washing activated carbon is usually for granular activated carbon, including coconut shell activated carbon and coal-based activated carbon. Acid-washed coconut shell activated carbon is mostly used in household drinking water, while the latter is mostly used in the chemical and food industries.
