Pumice pellets are used as a biological filtration media in odour control applications (bioscrubbers), in particular to assist in the removal of H2S, mercaptans, ammonia and volatile organic compounds. It is also used as a catalyst support media in the recovery of precious metals, as a lightweight resin fill and in the filtration of koi aquatic systems.
