Catalytic filtration media manganese dioxide

Catalytic filtration media manganese dioxide

Ref: 3.10.1


Price: £1,756.00 / €2,019.40 (Excluding VAT at 17.5%)

Catalytic filtration media is used in pressure filters with AFM at a ratio of 50:50. The media catalyses the dissociation of oxygen molecules into oxygen free radicals. These free radicals are highly reactive and will quickly oxidise metals and crack carbon double bonds in organic molecules. The media will also initiate disinfection of the water. If used in conjunction with ozone or hydrogen peroxide, higher concentrations of short lived ( fraction of a second) free radicals will be produced and the process will be more effective. Follow the hyperlink for more detailed information on this product.

The media is supplied in 25kg bags, minimum order quantity is a 1000 kg pallet load, price is per pallet load
