The reliable BioVyon^TM porous polyethylene disc diffusers, supplied by Porvair Filtration Group, are used in the breaking down of pollutants in sewage and industrial waste water, by the highly efficient transfer of oxygenated air.

A variety of pore sizes and permeabilities are available, ensuring a correct match to exacting customer aeration process requirements. Our diffusers can be supplied as a disc only, with or without a seal, or as a complete assembly  with the ability to be easily retrofitted into existing installations.

Other benefits include nominal operating costs, low back pressure, lightweight construction and resistance to damage and chemical attack in an aggressive wastewater environment.
