Pumice Odour Control Media


The use of our Pumice Odour Control Media (Lava Rock) in biofilters and bioscrubbers is increasing worldwide. It is a granular naturally occuring product that is a versatile alternative to traditional media such as mussel shells, plastic media, peat/heather and wood chips for use in biofilters, bioscrubbers and packed towers.


It is used to treat odours emanating from sewage treatment works, wastewater treatment works, industrial processes and industrial effluents. It’s used as the biomass support in the treatment of hydrogen sulphide, mercaptans and volatile organic compounds and has been installed throughout the UK by all the Water Plc’s.
