Plastic media BIOFILL® type B & BR

The product BIOFILL® type B  appears after more than 15 years of producing BIOFILL® type A, with the aim of giving an alternative product that doesn’t need so much surface and with a cheaper price. This product has a variation called BIOFILL® type BR (reinforced).

Both products have the same geometry, dimensions and specific surface. The only differences are the thickness and applications.

While the standard BIOFILL® type B is used in trickling filters which have a filling tallness equal or less than 4 m. and in gas-cleaning towers. BIOFILL® type BR is used in trickling filters which have a filling tallness over 4 m. and in air biological filters. Its mechanical resistance and large free volume allow the flow of air to treat. Its large surface allows growing bacteria colonies to eliminate volatile gases.
